    Abstract Positron emission tomography (PET) is a valuable tool for diagnosing malignant tumors. Intraoperative PET imaging is expected to allow the more accurate localization of tumors that need resections. However, conventional devices feature a large detector ring that obstructs surgical procedures, preventing their intraoperative application. This paper proposes a new PET device, Scratch-PET, for image-guided tumor resection. The key feature of Scratch-PET is its use of a hand-held detector to scan the surgical field, ensuring open space for surgery while measuring annihilation radiation with a fixed detector array placed below the patient. We developed a prototype device using two detectors: the hand-held detector and a fixed detector, to demonstrate the feasibility of the proposed concept. Both detectors consisted of 16 × 16 arrays of lutetium yttrium orthosilicates (3 × 3 × 15 mm3) coupled one-to-one with 16 × 16 silicon photomultiplier arrays. The position and orientation of the hand-held detector are tracked using an optical tracking sensor that detects attached markers. We measured a 22Na multi-rod phantom and two 22Na point sources separately for 180 s while moving the hand-held detector. The rod diameters were 6.0, 5.0, 4.0, 3.0, 2.2, and 1.6 mm. Each point source was placed at the field-of-view center and 35 mm off-center which was outside the sensitive area when the hand-held detector was positioned facing the fixed detector. The 2.2 mm rods were partially resolved, and both point sources were successfully visualized. The potential of the proposed device to visualize small tumors was validated.

    Abstract Purpose Despite a global decrease in the number of COVID-19 patients, early prediction of the clinical course for optimal patient care remains challenging. Recently, the usefulness of image generation for medical images has been investigated. This study aimed to generate short-term follow-up chest CT images using a latent diffusion model in patients with COVID-19. Materials and methods We retrospectively enrolled 505 patients with COVID-19 for whom the clinical parameters (patient background, clinical symptoms, and blood test results) upon admission were available and chest CT imaging was performed. Subject datasets (n = 505) were allocated for training (n = 403), and the remaining (n = 102) were reserved for evaluation. The image underwent variational autoencoder (VAE) encoding, resulting in latent vectors. The information consisting of initial clinical parameters and radiomic features were formatted as a table data encoder. Initial and follow-up latent vectors and the initial table data encoders were utilized for training the diffusion model. The evaluation data were used to generate prognostic images. Then, similarity of the prognostic images (generated images) and the follow-up images (real images) was evaluated by zero-mean normalized cross-correlation (ZNCC), peak signal-to-noise ratio (PSNR), and structural similarity (SSIM). Visual assessment was also performed using a numerical rating scale. Results Prognostic chest CT images were generated using the diffusion model. Image similarity showed reasonable values of 0.973 ± 0.028 for the ZNCC, 24.48 ± 3.46 for the PSNR, and 0.844 ± 0.075 for the SSIM. Visual evaluation of the images by two pulmonologists and one radiologist yielded a reasonable mean score. Conclusions The similarity and validity of generated predictive images for the course of COVID-19-associated pneumonia using a diffusion model were reasonable. The generation of prognostic images may suggest potential utility for early prediction of the clinical course in COVID-19-associated pneumonia and other respiratory diseases.

    RATIONALE AND OBJECTIVES: To analyze morphological changes in patients with COVID-19-associated pneumonia over time, a nonrigid registration technique is required that reduces differences in respiratory phase and imaging position and does not excessively deform the lesion region. A nonrigid registration method using deep learning was applied for lung field alignment, and its practicality was verified through quantitative evaluation, such as image similarity of whole lung region and image similarity of lesion region, as well as visual evaluation by a physician. MATERIALS AND METHODS: First, the lung field positions and sizes of the first and second CT images were roughly matched using a classical registration method based on iterative calculations as a preprocessing step. Then, voxel-by-voxel transformation was performed using VoxelMorph, a nonrigid deep learning registration method. As an objective evaluation, the similarity of the images was calculated. To evaluate the invariance of image features in the lesion site, primary statistics and 3D shape features were calculated and statistically analyzed. Furthermore, as a subjective evaluation, the similarity of images and whether nonrigid transformation caused unnatural changes in the shape and size of the lesion region were visually evaluated by a pulmonologist. RESULTS: The proposed method was applied to 509 patient data points with high image similarity. The variances in histogram characteristics before and after image deformation were confirmed. Visual evaluation confirmed the agreement between the shape and internal structure of the lung field and the natural deformation of the lesion region. CONCLUSION: The developed nonrigid registration method was shown to be effective for quantitative time series analysis of the lungs.

    A high-performance positron emission tomography (PET) scanner, which measures depth-of-interaction (DOI) information, is under development at the National Institute of Radiological Sciences in Japan. Image reconstruction methods with accurate modeling of the system response functions have been successfully used to improve PET image quality. It is, however, difficult to apply these methods to the DOI-PET scanner because the dimension of DOI-PET data increases in proportion to the square of the number of DOI layers. In this paper, we propose a compressed imaging system model for DOI-PET image reconstruction, in order to reduce computational cost while keeping image quality. The basic idea of the proposed method is that the DOI-PET imaging system is highly redundant. First, DOI-PET data is transformed into compact data so that data bins with highly correlating sensitivity functions are combined. Then image reconstruction methods based on accurate system modeling, such as the maximum likelihood expectation maximization (ML-EM), are applied. The proposed method was applied to simulated data for the DOI-PET scanner operated in 2-D mode. Then the tradeoff between the background noise and the spatial resolution was investigated. Numerical simulation results show that the proposed method followed by ML-EM reduces computational cost effectively while keeping the advantages of the accurate system modeling and DOI information.

    Mexican Codices are an ancient reading and writing system, part of this cultural legacy date from the 16(th) and 17(th) century. For preservation reasons, the collection know as "Collection of Original Mexican Codices" under the custody of the National Library of Anthropology and History in Mexico City is kept under limited access and controlled illumination conditions. It is presented an accurate color reproduction of Codices under simulated average daylight based on spectral reflectance estimation from statistical spectral data using the Wiener estimator, removing the original capture environment illumination. We compare the achieved results between both, a 16 bands multispectral camera and a RGB Nikon D1 camera.

    A detector proposed by Murayama et al. for detection of depth-of-interaction (DOI) in PET consists of three-dimensionally arranged crystal elements with proper optical reflectors and is coupled to an array of photomultiplier tubes. This detector has a great advantage in easiness and cost in fabrication. We implemented a simulator of this detector that allows us to find appropriate values of parameters such as optical properties of crystal or detector unit geometry before making detectors. The simulator is based on the Monte Carlo method that traces the migration of optical photons generated by interaction of a gamma ray with crystal. First, the simulator performance was validated by comparing with the experimental data obtained with some prototype detectors. Then, on some parameters including refractive index of inter-crystal material, reflectance of optical reflector and detector geometry, appropriate values were investigated for accurate discrimination of crystal element of interaction.

    Standard Object Colour Spectra Database for Colour Reproduction Evaluation (SOCS)', which contains about 50,000 object color reflectances/transmittances, was published as a Japanese Industrial Standard Technical Report (JIS-TR) in 19981. To promote, widen and standardize usage of SOCS, we selected representative data sets, including both typical sets and difference sets. Typical set samples have average characteristics of whole data in an object group, and difference set samples have metameric characteristics to corresponding typical set samples, respectively. This paper describes concepts, purposes and algorithms by which they were selected from many spectral data samples. A total of 365 representative data samples (235 samples for typical sets and 130 samples for difference sets) were selected and evaluated to determine whether they meet the purposes for the sets. An experiment verified that they are very useful in the following applications. (a) Determination of simple color correction matrix using typical sets. (b) Easy evaluation of color reproduction quality for color sensors by a combinatorial use of typical and difference sets. ISO/TC130/WG2 is discussing SOCS as a new ISO technical report. The above-mentioned representative data sets will be the principal part of the technical report.

    Backward model for multi-primary display, which gives digital count in order to present a given color stimulus value XYZ on a screen, is proposed in this paper. Performance of the proposed method is evaluated with 6-primary display. Error in predicting XYZ of colors projected on a screen was 0.8 on average and 2.9 at maximum.

    Relative amounts of pigments on an overhead projector (OHP) sheet printed by laser printer can be estimated by using spectral transmittance at each pixel of an optical micrograph, and the multi-layered pigments also can be separated into each component. The transmittance spectra were estimated from multiband images by the Wiener estimation method. In the experiment, relative amounts of pigments printed by one or two kinds of color pigments were estimated, and overlapping magenta and yellow pigments were separated into each category. The result was accurate as compared with separation based on RGB values.

    The spectral reflectance of most reflective objects, such as natural objects and color hardcopy, is relatively smooth and can be approximated by several principal components with high accuracy. Although the subspace spanned by those principal components represents a space in which reflective objects exist, it does not provide the limit of the object distribution or the gamut. In this paper we propose to represent the gamut of reflective objects as a convex polyhedron in the subspace spanned by several principal components. The concept of the polyhedral gamut representation based oil the spectral reflectance database and its application to the calculation of metamer ensembles are described. The color-mismatch volume caused by different illuminam and/or observer for a metamer ensemble is also calculated and compared with the theoretical ones.

    At the IEEE MIC 1999, we presented a Monte Carlo simulator made for designing a depth encoding multicrystal detector and reported some simulation results. While the basic performance of the simulator was validated from the comparison between the simulator outputs and experimental results using a prototype detector, many factors to be implemented were still remaining for simulating real phenomena inside the detector. This time, we improved the simulator by including Compton scattering, more accurate migration of optical photons at every interface of materials, and so on. Using this simulator, discrimination characteristics were investigated with respect to thickness of scintillator block, refractive index of inter-stage material, reflectance of optical reflector and surface roughness of scintillator. From these investigations, useful information for detector design was obtained.

    TAO* has developed six-primary HDTV display system. Two DLP™ projectors that have different three primaries superimpose two images on a screen. These six primaries almost covers (Pointer + SOCS) gamut, which is a typical example of natural reflective objects around us. Volume of six-primary display gamut is larger than sRGB display gamut at 1.6 times.

    Spectral reflectance of most reflective objects such as natural objects and color hardcopy is relatively smooth and can be approximated by several numbers of principal components with high accuracy. Though the subspace spanned by those principal components represents a space in which reflective objects can exist, it does not provide the bound in which the samples distribute. In this paper we propose to represent the gamut of reflective objects in more distinct form, i.e., as a polyhedron in the subspace spanned by several principal components. Concept of the polyhedral gamut representation and its application to calculation of metamer ensemble are described. Color-mismatch volume caused by different illuminant and/or observer for a metamer ensemble is also calculated and compared with theoretical one.

    Functional images obtained PET and/or SPECT become more useful when those images are provided with detail anatomical information obtained by X ray CT or MRI. In this paper a series of image processing including image registration and segmentation is presented for quantitative analysis of functional images. A clinical application described here is to evaluate the effect of radiation therapy for lung cancer on lung functions quantitatively. Though SPECT images give information on lung functions such as ventilation and perfusion, it is difficult to identify correctly the location and amount of radioactivity distribution with only those images. To overcome this difficulty, we synthesize both anatomical image (X ray CT, or shortly XCT) and functional image (SPECT) effectively. Furthermore, we have developed a method for dividing lung in XCT image into the lobes that are anatomically meaningful. The segmented lobes in XCT image can be used for quantitative evaluation in each lobe. Change in perfusion at each lobe of lung along with the therapy is presented as an effective example.

    Mapping pigmentation in human skin is expected to give useful information in reproducing skin color and enhancing the ability to diagnose various skin disease. In this research, maps of melanin, oxy-hemoglobin and deoxy-hemoglobin in skin are estimated from multi-channel visible spectrum image by using an inverse optical scattering technique. In the inverse optical scattering technique, first of all, a forward model of optical scattering is built to simulate the spectral reflectance of skin. Changing the variable parameters in the forward model, we repeat the simulation until the simulated spectral reflectance matches with the spectral reflectance at each pixel of the multi-spectral image. The principle of the proposed estimation technique was confirmed by imaging the human forearm under conditions of the venous occlusion, the venous and arterial occlusion, and by imaging a slapped region of the human forearm.

    We propose a method for extracting goniospectral information of three-dimensional objects from multiband images obtained under several illuminants and reproducing the objects under various kinds of illuminants. Using the dichromatic reflection model, goniophotometric information of both diffuse component and specular component is estimated from the images acquired under the illuminant from several illumination directions. On the other hand, spectral information is estimated from five band images using the minimum mean square error criterion. Experimental results using simple three-dimensional objects are presented to demonstrate the basic performance of the proposed method.
