    摘要： A radiological imaging apparatus of the present invention comprises an image pickup device and a medical examinee holding device that is provided with a bed. The image pickup device includes a large number of radiation detectors and radiation detector support plates. A large number of radiation detectors are mounted around the circumference of a through-hole and arranged in the axial direction of the through-hole. The radiation detectors are arranged in three layers formed radially with respect to the center of the through-hole and mounted on the lateral surfaces of the radiation detector support plates. Since the radiation detectors are not only arranged in the axial direction and circumferential direction of the through-hole but also arrayed in the radial direction, it is possible to obtain accurate information about a γ-ray arrival position in the radial direction of the through-hole (the positional information about a radiation detector from which a γ-ray image pickup signal is output). The use of accurate information about γ-ray arrival increases the tomogram accuracy. As a result, the present invention enhances the tomogram accuracy, that is, the PET examination accuracy.

    摘要： The contents of a distortion compensation table for adjusting a waveform of a signal input to an amplification apparatus are more precisely adjusted to suppress distortion occurring in an output signal. A table value calculation unit exercises adaptive control over compensation data I and Q according to the perturbation method using power series to update a power series distortion compensation table when distortion of an output signal from a power amplification unit is greater than a first threshold used in the adaptive control process performed on the compensation data I and Q according to the perturbation method using power series. When the distortion of the output signal from the power amplification unit is smaller than the first threshold used in the adaptive control process performed on the compensation data I and Q according to the perturbation method using power series, the table value calculation unit performs an adaptive control process on the compensation data I and Q according to the perturbation method based on interpolation using representative points to update a representative point interpolation distortion compensation table.

    摘要： An image pickup apparatus of a radiological imaging apparatus includes a plurality of radiation detectors arranged in a ring form around a through hole section formed on a casing into which an examinee is inserted. An X-ray source unit having an X-ray source moves in a circumferential direction of the through hole section along a ring-shaped guide rail provided on the casing. Each radiation detector outputs both an X-ray detection signal which is a detection signal of X-rays that have passed through the examinee and a γ-ray detection signal which is a detection signal of γ-rays radiated from the examinee caused by radiopharmaceutical. A computer creates an X-ray computed tomographic image data based on the X-ray detection signal and a PET image data based on the γ-ray detection signal and creates fused tomographic image data using the X-ray computed tomographic image data and the PET image data.

    摘要： An imaging apparatus of a radiological imaging apparatus is provided with a first and a second radiation detectors disposed around a hole portion into which a bed is inserted. The first radiation detector includes a detecting portion formed of GaAs of a square having a side of 5 mm and having a thickness of 2 mm. The second radiation detector includes a detecting portion formed of CdTe of a cube having a side of 5 mm. The first radiation detector detects X-rays emitted from an X-ray source and transmitted through an examinee and does not detect γ-rays emitted from the examinee. The second radiation detector detects above X-rays and γ-rays. An X-ray signal processing apparatus processes an X-ray image signal from the first radiation detector and outputs intensity information thereof. A signal discriminating apparatus processes a γ-ray image signal from the second radiation detector and outputs a pulse signal. Thus, the radiological imaging apparatus capable of carrying out radiation examination of the subject by using X-rays and γ-rays can be simplified.
