Abstract

The invention provides a calibration target and a medical imaging system. The calibration target comprises a calibration target substrate and a plurality of markers embedded in the calibration target substrate; the calibration target substrate comprises a first calibration target substrate and a second calibration target substrate, and the plurality of markers comprise a plurality of first markers embedded in the first calibration target substrate and a plurality of second markers embedded in the second calibration target substrate; and the total number of the plurality of first markers is greater than or equal to a first threshold number. According to the invention, the number of the first markers is increased, so that the calibration precision of calibration through the calibration target is improved, and the installation precision requirement of the calibration target is reduced.

Description

technical field [0001] The invention relates to the technical field of calibration, in particular to a calibration target and a medical imaging system. Background technique [0002] Medical imaging systems such as C-arm imaging systems and CT machines are one of the large-scale medical equipment commonly used in hospitals at present. They can generate tomographic images in real time during operations, and can help doctors diagnose and monitor operations in a timely manner during operations. The medical imaging system needs to be registered before use, and in the registration, the core and most critical step is to calibrate the medical imaging system. To calibrate the medical imaging system, it is necessary to use the calibration target. By calibrating the three-dimensional coordinates of the marked points on the target and the two-dimensional coordinates of the pixels of the marked points in the X-ray image, the internal and external parameters of the medical imaging system ...
