Abstract: A detector ring has a first unit and a second unit that are rotatably movable and an auxiliary unit movable in a central axis direction. The auxiliary unit is moved in the central axis direction relative to the units. The detector ring forms into a C shape to form a clearance. Subsequently, the first unit and the second unit are rotatably moved to move the clearance of the detector ring to a position distant from a support member. A patient can be introduced from the clearance. The detector ring is returned to an annular shape in the reverse sequence of the above one with the patient introduced. A annihilation radiation pairs can be detected from all directions to take a tomographic image, and a functional image with higher image quality than that of a conventional configuration can be obtained.

Abstract: A needle biopsy apparatus includes: a hollow needle for needling a patient; and a main body portion which retains the needle, and acquires a tissue of the patient through the needle. The needle is configured of gas not including a radioactive label, a liquid not including a radioactive label, or a solid not including a radioactive label, and includes a labelling portion of which a radiation dose to be detected is less than that of the tissue of the patient ingesting a radioactive-labelled radiopharmaceutical dosed to the patient, on a tip end side.

Abstract: With a mammography PET apparatus, a supporting face includes a detector ring region, and a detector-outside region as an outside area of the detector ring region. The detector ring region is higher than the detector-outside region. An elastic lower-layer mat is disposed on the detector-outside region. An upper-layer mat, softer than the lower-layer mat, is disposed on the detector ring region and the lower-layer mat across a boundary between the detector ring region and the lower-layer mat. Accordingly, an edge of the lower-layer mat harder than the upper-layer mat is covered with the upper-layer mat, leading to alleviation of pain to a subject M caused by the edge of the lower-layer mat.
