Problems solved by technology

When conducting brain function research, it is inconvenient to conduct visual brain function research because the head of the subject is completely surrounded by the detector, and some subjects will have a sense of claustrophobia, which will affect the brain of the subject Function

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] like figure 1 As shown, a head PET device for rapid imaging, the detector array 1 includes a plurality of detector modules 2, the detector modules 2 are arranged on a capsule-like curved surface, and the bottom of the detector array 1 is opened to accommodate the scanned subject's neck. There is a removable eye detector module 3 on the detector array 1, and the eye detector module 3 can be removed when performing visual research or eliminating the claustrophobic feeling of the scanned object.

[0012] In order to improve the sensitivity, the opening at the bottom should be as small as possible, so that the head of the object to be scanned cannot enter through the neck opening of the detector. In order to solve this problem, the PET detector array is designed as a detachable structure. Before scanning, the detector array is first opened, and after the head of t...

Abstract

The invention discloses a head PET device for rapid imaging and an imaging method. A detector of the PET device comprises multiple detector modules, and the detector modules are aligned on a quasi-capsule curve face of an opening; removable eye detectors are arranged on the detector array so as to facilitate the visual study and elimination of claustrophobia of a scanned object; the detector arrayis a separable structure; before the head imaging, the detector is separated; after the head part of the scanned object enters the detector, the detector is closed and scanning is completed.

Description

technical field [0001] The invention relates to the field of nuclear medicine imaging equipment, in particular to a head PET device and an imaging method for rapid imaging. Background technique [0002] Positron Emission Tomography (PET) is widely used in the fields of tumor, cardiovascular and nervous system. The sensitivity of clinical whole-body PET equipment is too low due to the large aperture, and the scanning time of a single bed is usually several minutes. In the field of nervous system applications, it is sometimes necessary to perform rapid imaging of the human brain in seconds, which requires the development of special high-sensitivity brain-specific equipment. When conducting brain function research, it is inconvenient to conduct visual brain function research because the head of the subject is completely surrounded by the detector, and some subjects will have a sense of claustrophobia, which will affect the brain of the subject Function. Therefore, it is nece...
