Problems solved by technology

[0003] However, the inventors found during the research that due to the irregularity and specificity of cardiac motion, using a single diastolic and systolic phase for different scanning objects will not be able to accurately reflect the cardiac motion of different scanning objects, and may cause Cardiac reconstruction images produce relatively serious motion artifacts

Abstract

The invention provides a CT (Computed Tomography) scanning method and device for heart. The method comprises the following steps: pre-scanning the heart information of an object to be scanned to obtain initial scanning data; reconstructing a plurality of initial heart images at different period phases according to the initial scanning data; determining an optimal period phase of the object to be scanned according to the plurality of initial heart images; performing final scanning on the heart of the object to be scanned based on the optimal period phase. In the embodiment of the invention, the X-ray radiation dosage of a patient in a scanning process can be lowered, the risk of more X-ray irradiation on the patient is lowered on the premise of ensuring the heart image quality, and the correctness and effectiveness of diagnosis can be ensured.

Description

technical field [0001] The present application relates to the technical field of medical data processing, in particular to a heart CT scanning method and device. Background technique [0002] When scanning the heart of a CT scan object (such as a patient who needs to be diagnosed or a user with other needs), it is necessary to determine the out-phase (such as diastole and systole) to perform a CT scan. Generally, about 75% of the relative phase of diastole and about 30% of relative phase of systole are used for CT scanning. [0003] However, the inventors found during the research that due to the irregularity and specificity of cardiac motion, using a single diastolic and systolic phase for different scanning objects will not be able to accurately reflect the cardiac motion of different scanning objects, and may cause The reconstructed images of the heart produce serious motion artifacts. However, if the projection data is obtained by helically scanning all the phases, the...
