    摘要： In a case that a gamma ray has entered into a plurality of scintillators adjacent to each other simultaneously, a detector detects the gamma ray having entered simultaneously. A position calculator calculates the ratio of wave heights representing the energies of the detected gamma ray. The position calculator obtains a trajectory of such a gamma ray that a ratio of distances passed by the gamma ray inside the plurality of scintillators, respectively, coincides with the ratio of the wave heights. The position calculator obtains an intersection between the boundary of the plurality of scintillators and the trajectory, as a passing position of the gamma ray. A reconstructing part executes a back projection process with the trajectory passing through the calculated passing position as a projection position.

    摘要： According to one embodiment, a nuclear medicine diagnosis includes a light signal generating unit, photodetection unit, measurement unit, calculation unit, and storage unit. The light signal generating unit repeatedly generates light signals. The photodetection unit repeatedly generates first output signals corresponding to intensities of the light signals, repeatedly generates second output signals corresponding to intensities of gamma rays emitted from a subject. The measurement unit repeatedly measures light signal detection times and repeatedly measures gamma ray detection times. The calculation unit calculates a difference between a target gamma ray detection time and a target light signal detection time of the light signal detection times for each of the gamma ray detection times. The target light signal detection time is measured before the target gamma ray detection time. The storage unit stores the calculated difference in association with a target second output signal of the second output signals.

    摘要： In a nuclear medicine imaging apparatus as a medical image diagnosis apparatus according to one embodiment, a PET detector is configured to detect a gamma ray emitted from a nuclide introduced into a body of a subject. A PET image reconstruction unit is configured to reconstruct a nuclear medicine image (PET image) as a medical image from the gamma ray projection data created based on the gamma ray detected by the PET detector using successive approximation. A controller is configured to control the PET image reconstruction unit to change the parameter used in the successive approximation depending on information regarding the scanning region in the body of the subject.

    摘要： A list of a plurality of reference images is displayed. Parameters pertaining to signal acquisition, image generation, and image display are related to each of these reference images. When the operator selects one desired reference image from the list, a signal is acquired and an image is generated and displayed in accordance with the parameters related to the selected reference image. The only operation which the operator must perform is to select a reference image visually close to a desired medical image. The apparatus automatically sets detailed signal acquisition parameters, image generation parameters, and image display parameters which the operator need not know.
