 Appl.No PCT/JP2022/041108 Applicant FUJITSU LIMITED Inventor NAKAMURA, Fuya
The present invention reduces the difference between methods for capturing images to be used for machine-learning.　The information processing device generates a histogram that indicates the number of pixels for each brightness value of a first image of a first subject captured in a first image-capturing condition. In addition, the information processing device generates a histogram that indicates the number of pixels for each brightness value of a second image of a second subject of the same type as the first subject captured in a second image-capturing condition. Then, the information processing device generates a conversion rule, by which the similarity of the histogram of the first image and the histogram of the second image is improved, for the pixel brightness values of the second image. Then, the information processing device converts, according to the conversion rule, the brightness value of each pixel of a third image of a third subject of the same type as the first subject captured in the second image-capturing condition. In addition, the information processing device executes machine-learning using the third image of which the brightness values are converted.

A conversion model construction device for constructing a conversion module for converting an image type according to the present invention comprises: a memory in which a conversion model construction program is stored; and a processor that runs the conversion model construction program. The conversion model construction program: converts a first training image of a first type into a first converted image of a second type through a first generation module; applies the first converted image and a second training image of the second type to a first determination module, thereby updating the first generation module so that the first converted image is determined as real; converts the first converted image into a second converted image of the first type through a second generation module; and compares the second converted image with the first training image to update the first generation module, thereby training the conversion model. The conversion model includes the first generation module, the second generation module, and the first determination module. The first generation module processes the image of a first type into that of the second type and the second generation module processes the image of the second type into that of the first type. The first determination module determines at least one input image to be real or fake according to a set condition. The first type is the type of images captured by positron emission tomography (PET) or computerized tomography (CT), and the second type is the type of images captured by magnetic resonance imaging (MRI).

Providing an X-ray measurement with a reduction in the measure of scattered photons is significantly advantageous over measurements with a usual contribution of scattered photons. Using a temporal point spread function (TPSF) of the detected photons, for each source-detector location, to discriminate the scattered photons from the ballistic photons is used to significantly relax the temporal resolution requirement at the time-sensitive X-ray detector of the X-ray imager when compared to the low temporal resolution required when the discrimination is carried out on a photon-by-photon basis. Using the TPSF dataset provides better estimates of the measure of ballistic photons with a reduction in the measure of scattered photons which are also used to generate X-ray images with an improvement in CNR.
