Gamma camera special for mammary glands based on CZT

Abstract

The invention discloses a gamma camera special for mammary glands based on CZT. The gamma camera comprises a main case, an overhauling cabinet door, a working table, casters, an electric pushing rod, a CZT detector, a cantilever structure, a display support and a display. The overhauling cabinet door is arranged outside the main case, the working table is arranged on one side of the upper portion of the main case, and the cantilever structure is arranged on the other side of the upper portion of the main case; the display support is arranged on the working table, the display is arranged above the display support, and the casters are arranged below the main case; the gamma camera also comprises a lifting guiding rail, the lifting guiding rail is installed above the cantilever structure, a supporting plane is installed at the bottom of the lifting guiding rail, and the CZT detector is installed above the supporting plane and is capable of being installed on the lifting guiding rail in a sliding mode. According to the gamma camera special for the mammary glands based on the CZT, a supporting face plate is arranged below the CZT detector and used for fixing and slightly extruding a breast, artificial moving of the mammary glands is prevented, the thickness of the breast is reduced, and lesion points are more easily detected through the detector.

Description

technical field [0001] The invention relates to nuclear medicine imaging equipment, in particular to a CZT-based gamma camera dedicated to mammary glands. Background technique [0002] Nuclear medicine imaging is based on the difference in radioactivity inside and outside the organ and the local radioactivity difference inside the organ. The level of radioactivity in organs and lesions is directly related to the accumulation of imaging agents, which in turn depends on Therefore, nuclear medicine imaging can not only display the location, shape and size of organs and lesions, but more importantly, provide information on blood flow, function and metabolism at the same time. etc. information. [0003] Abnormal blood flow, function and metabolism are often the early changes of the disease, which can appear before the morphological structure changes, so nuclear medicine imaging is often helpful for the early diagnosis of the disease, and is widely used in the organ and functiona...

Problems solved by technology

Because the probe of the conventional gamma camera is relatively large, usually with a large field of view of 40-60 cm, it can detect a large range, but it is not easy to get close to the body surface, and it is far away from the target, so the detection efficiency (gamma count rate) is reduced, which affects its resolution and sensitivity
