Medical imaging device and scanning method thereof

Abstract

The invention provides a medical imaging device and a scanning method thereof. The medical imaging device and the scanning method thereof are applied to the technical field of medical equipment, and the detection efficiency is improved to a certain extent. The scanning method of the medical imaging device comprises the steps that scanning area information or scanning position information is acquired; according to the scanning area information or the scanning position information, a scanning area of an object to be detected is determined; from a plurality of detector units, a first detector unit group corresponding to a first scanning area and a second detector unit group corresponding to a second scanning area are determined; a first scanning parameter corresponding to the first scanning area is acquired, according to the first scanning parameter, the first scanning area is scanned by using the first detector unit group, and first sampling data is obtained.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical imaging equipment and a scanning method thereof. Background technique [0002] With the continuous development of the medical field, through the use of different scanning imaging equipment and scanning imaging technology, the judgment of the cause of the patient is becoming more and more accurate. Among them, the PET (Positron Emission Computed Tomography, Positron Emission Computed Tomography) system is Advanced clinical examination imaging technology in the field of nuclear medicine. [0003] During the inspection process using the PET system, a certain substance (generally a substance necessary for the metabolism of biological life, such as glucose, protein, etc.) is injected into the body of the subject (for example, a patient), and the short-lived substance is marked on the substance The radionuclide (such as 18F, 11C, etc.), then let the subject lie on ...

AI Technical Summary

Problems solved by technology

[0004] Most of the PET systems in the prior art have only one detection cavity, which detects one object at a time. For a PET system with a long cavity, it is easy to cause waste of resources. Therefore, there is a lack of a PET system that can detect multiple objects at the same time.
