Embodiment Construction
[0051] In the following description, numerous details are provided in order to provide a thorough understanding of the invention. It will be appreciated, however, to those skilled in the art that the following description is merely illustrative of preferred embodiments of the invention, and that the invention may be practiced without one or more of these details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.
[0052] Once a traditional emission imaging device is built, its dimensions in all directions are fixed. The present invention provides a PET system detector ring position adjustment unit (hereinafter referred to as the detector ring position adjustment unit) used for emission imaging equipment. The detector ring position adjustment unit can provide a detector radial position (that is, detect ring aperture) adjustable emission imaging device. In a preferred embodiment, an emissi...

The invention discloses a pet system detector ring position adjusting unit and a transmitting imaging device. The position adjustment unit includes a fixed plate and a rotating plate. A central hole and N sliding grooves distributed in radial spoke and arranged around the center hole are formed in the fixed plate, each sliding groove is connected with a moving part, and a detector is arranged on each movable part. The rotating plate is arranged side by side with the fixed plate in the radial direction of the center hole, a center through hole corresponding to the center hole and N guide grooves distributed in radial spoke and arranged around the center through hole are formed in the rotating plate, and guide grooves are curved segment grooves on the Archimedes Helix. The movable parts correspond with the guide grooves one to one, and when the rotating plate rotates under the action of a driving part, the movable parts move in the radial direction along the sliding groove under the guidance of the guide grooves to drive the detector on the sliding grooves. The position adjusting unit of the pet system detector ring position adjusting unit is convenient to install and adjust, high inadjusting efficiency, and is convenient to process and overhaul.
Description
technical field [0001] The invention belongs to components of medical imaging equipment, and in particular relates to a PET system detector ring position adjustment unit and emission imaging equipment, which can change the position of the positron emission tomography detector ring to adapt to parts of different sizes of the body, thereby Improve the sensitivity of the device. Background technique [0002] Positron emission tomography (PET) is a special medical imaging device that can construct an image of the site to be tested to reflect its physiological function according to the specific distribution of radioactive tracers in the human body or animal living body. Existing PET systems include detector rings, data acquisition systems, image reconstruction software, and mechanical components such as hospital beds. [0003] The detector ring of the existing PET system is surrounded by a plurality of detectors to form a ring device, and the aperture size of the ring surrounded...
