Abstract: The image reconstruction processing method estimates, in a substance information estimation process, substance information from a reconstructed image for every image update in an image update process, and uses the estimated substance information to update images based on succeeding calculations by successive approximation formulae of a successive approximation method. Since the substance information is estimated, the present methodology can be applied regardless of whether the constituent substance of an imaging sample is known. Further, because the substance information is estimated (updated) from the reconstructed image for every image update in the image update process, reliable substance information can be estimated by avoiding the problem of continuously using the substance information estimated at a point of time where a repeat count (iteration count) by successive approximation formulae is low and at a point of time where the repeat count is high.

Abstract: A radiation imaging apparatus avoids collisions of the radiation with an obstacle, and includes a flat panel detector (FPD) connected with a supporting axis facing a vertical direction to a ray detection surface. A supporting axis is supported rotatably due to the action of the bearing and the flat panel detector rotates around the supporting axis as the center of the rotation via the supporting axis by driving with the motor. A frame member surrounding the flat panel detector has a circular outer appearance of which a center is the supporting axis, and the diameter of the frame member is longer than the length of the diagonal line of the flat panel detector.
Abstract: A radiation imaging apparatus performs pre-shot imaging while considering the imaging condition on the tomosynthesis imaging which can be performed right thereafter without repeating a positioning of the radiation irradiation unit on the tomosynthesis imaging. The protocol for the per-shot imaging is read out. Reading out the protocol is executed by that the operator of operation unit of the console and the console 1 reads out the protocol for the pre-shot imaging from the radiology department information system along with the patient information. Therefore, the imaging condition of the protocol for the continuously executed tomosynthesis imaging is read out while linking the protocol of the pre-shot imaging.

Abstract: A model constructed by a training process using the technique of deep learning using the training data including images created from a large number of chromatograms and correct peak information is previously stored in a trained model storage section. When chromatogram data for a target sample acquired with an LC measurement unit are inputted, an image creator converts the chromatogram into an image and creates an input image in which one of the two areas divided by the chromatogram curve as the boundary in the image is filled. A peak position estimator inputs the pixel values of the input image into a trained model using a neural network, and obtains the position information of the starting point and/or ending point of the peak and a peak detection confidence as the output. A peak determiner determines the starting point and/or ending point of each peak based on the peak detection confidence.
Abstract: For the separation of a peptide or protein in a sample using a supercritical fluid chromatograph, carbon dioxide is used as the supercritical fluid, while an organic solvent containing hexafluoroisopropanol is used as the modifier to be added to the supercritical fluid. If a mixed liquid of methanol, isopropanol, water and formic acid is simply used as the modifier, a considerable amount of peak tailing occurs on the chromatogram, causing the peak waveform to be distorted. By comparison, when a mixed liquid prepared by additionally mixing hexafluoroisopropanol in the mixed liquid of methanol, isopropanol, water and formic acid is used, the peak observed on the chromatogram will have a sharp, satisfactory shape.
