摘要： According to one embodiment, a blood flow perfusion analyzing apparatus includes tissue and arterial TCC calculation units, first and second making units, a deconvolution unit and a blood flow information calculation unit. The tissue TCC calculation unit obtains tissue TCCs. The arterial TCC calculation unit calculates an arterial TCC. The first making unit makes first sets, starting from a first time in which elements corresponding to the tissue are arrayed one-dimensionally, based on the tissue TCCs. The second making unit makes a second set, starting from a second time after the first time, in which elements corresponding to the artery are arrayed two-dimensionally, based on the arterial TCC. The deconvolution unit calculates transfer functions of the tissue based on the first and second sets. The blood flow information calculation unit calculates information on a blood flow perfusion based on the transfer functions.

摘要： A medical data generating apparatus includes a data processing unit, a work-status data generation unit, a display unit and a work-status restoration unit. The data processing unit acquires medical data from a database to perform data processing. The work-status data generation unit generates work-status data as a data record of medical data. The work-status data indicates a work status of the data processing. The display unit acquires medical data including at least one piece of work-status data from the database to list the acquired pieces of the medical data on a display device together with identification information of the acquired piece of the work-status data. The work-status restoration unit restores a work status of a data processing corresponding to a selected piece of work-status data based on the selected piece of the work-status data.

摘要： A detector having a collimator in a position at a specific angle with respect to a therapeutic X-ray beam is mounted to selectively detect only scattering radiation in the direction. To three-dimensionally obtain a distribution of places where scattering occurs in a patient body, a detector is rotated during irradiation and scattering radiation is measured from all of directions. After that, a reconstructing process is performed, and a distribution of occurrence of scattering radiation in the subject is three-dimensionally imaged. Since angles and amounts of X-rays scattered by Compton scattering are known theoretically, if scattering radiation at a certain angle can be detected, the number of scattering radiation at other angles can be also estimated. On the basis of the theory, images of distribution of scattering radiation sources are converted to images of distribution of absorption of radiation.

摘要： An examination-item database storing a plurality of types of examination items capable of examining a predetermined disease and attributes of these examination items so as to correspond to one another is prepared, the degree of risk for the predetermined disease is calculated based on individual physical information, a criterion for selection of an examination item for examining the predetermined disease is generated in accordance with the calculated degree of risk, and an examination item having an attribute meeting the selection criterion is searched out from the examination-item database. In addition, the calculated degree of risk and the examination-item database are displayed so as to correspond to the predetermined disease. This makes it possible to perform the optimal examination for each individual in accordance with the degree of risk, thereby improving the efficiency of detection of a disease. Moreover, reduction of superfluous examinations makes it possible to reduce physical and psychological burdens imposed on a patient by examinations.
