摘要: In the case where X-ray tubes and X-ray detectors have fixed directions (directions of irradiation and directions of detecting planes), X-ray fluoroscopy can be carried out from various directions by providing two U-shaped tracks for the X-ray tubes and the X-ray detectors, each having two straight tracks arranged opposite each other, and a curved track connected thereto. An increased number of directions for X-ray fluoroscopy can be secured by arranging a U-shaped track rail for the X-ray tubes and a U-shaped track rail for the X-ray detectors opposite each other when seen in plane view.

摘要: An organism is irradiated with therapeutic radiation from a radiation irradiation device. A pair of two-dimensional radiation detectors are arranged so as to face one another with the irradiated therapeutic radiation passing therebetween, and detect the two-dimensional positions irradiated by a pair of annihilation γ rays produced when a positron emitted from a positron-emitting radionuclide is annihilated. On the basis of a pair of positions detected by the pair of two-dimensional radiation detectors, a radionuclide position detecting unit detects the position of the positron-emitting radionuclide, and the radiation irradiation device irradiates the position of the positron-emitting radionuclide with therapeutic radiation.

摘要: Light emitted in correspondence to ionizing radiation incident from a scintillator is fed through an optical fiber to a photoelectron multiplier tube by which it is converted to an electrical signal. The electrical signal is amplified by a signal amplifying circuit, and any light emission events of given or higher intensity are discriminated by a discriminator and counted by a counter. The count value is fed to a computer. The computer converts the count value to a dosage on the basis of an exponential relationship lying between the light emission intensity and the number of emission events, thereby attaining detection of the dosage.
