Abstract: When chromatogram data for a target sample have been acquired, a peak position estimator determines an estimated result of the position of the starting and/or ending point of a peak as well as the confidence value representing the reliability of the estimation, using a trained model stored in the trained model storage section. Normally, a plurality of estimated results of the starting point and/or ending point of the peak are acquired for one peak. A peak information correction processor identifies a candidate having the highest confidence as a prime candidate, and superposes a plurality of candidates including the prime candidate, with their respective confidence values, on a displayed chromatogram. An operator referring to the confidence values selects a peak which needs close checking or correction, and corrects the starting point and/or ending point of the selected peak, for example, by selecting and indicating a candidate other than the prime candidate.
Abstract: A radiation tomograph whereby the acquisition of transmission data and the measurement of annihilation radiation pairs are simultaneously performed by a single detector ring so as to realize both reduction of the manufacturing cost of a PET device and reduction of a burden to a subject. The transmission data, which shows the distribution of annihilation radiation absorption characteristics within a subject, is computed from data relating to annihilation radiation pairs in the vicinity of a surface of the subject. The transmission data can be acquired by detecting a radioactive drug derived from the subject, which makes imaging exclusively for transmission data unnecessary.

The front end of the reinforcing member is linked to the cylindrical support member in the front structure. The upper surface of the reinforcing member is fixed to the upper floor and the lower surface of the reinforcing member is fixed to the lower floor.

Abstract: An operation pipe and a device equipped with the operation pipe, which use a gel to perform operations such as separation, extraction, purification, elution, recovery, analysis and the like of target components that are biological components such as nucleic acids. More specifically, an operation pipe and a device, with which it is possible to perform operations such as separation, extraction, purification, elution, recovery, analysis and the like of target components in a sealable pipe by operating magnetic particles in the pipe under a magnetic field from outside of the pipe.
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: An ion transfer apparatus for transferring ions from an ion source at an ion source pressure, which ion source pressure is greater than 500 mbar, along a path towards a mass analyser at a mass analyser pressure that is lower than the ion source pressure. The apparatus includes a plurality of pressure controlled chambers, wherein each pressure controlled chamber in the ion transfer apparatus includes an ion inlet opening for receiving ions from the ion source on the path and an ion outlet opening for outputting the ions on the path. The plurality of pressure controlled chambers are arranged in succession along the path from an initial pressure controlled chamber to a final pressure controlled chamber, wherein an ion outlet opening of each pressure controlled chamber other than the final pressure controlled chamber is in flow communication with the ion inlet opening of a successive adjacent pressure controlled chamber.
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: 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.
