Embodiment 1
[0047] Such as figure 1 As shown, this embodiment provides a method for constructing a three-dimensional model of the heart used in cardiac radiotherapy, including the following steps:
[0048] Obtain a three-dimensional cardiac electrophysiological map and a corresponding three-dimensional image set of cardiac cross-section;
[0049] Perform a registration operation on the current 3D cardiac electrophysiological map and the 3D cross-sectional image set of the heart to obtain a preliminary 3D model of the heart;
[0050] Judging whether there are artifacts in the current preliminary three-dimensional heart model, if yes, then re-acquire the three-dimensional cardiac electrophysiological map and / or three-dimensional image set of cardiac cross-section, and then perform the registration operation again, if not, then according to the current preliminary three-dimensional cardiac model The electrophysiological data and graphic data are used to obtain the three-dimensional structur...
Embodiment 2
[0056] The technical solution provided in this embodiment is a further improvement made on the basis of the technical solution in embodiment 1. The difference between this embodiment and embodiment 1 is:
[0057] In this embodiment, when obtaining the preliminary three-dimensional model of the heart, the specific steps are as follows:
[0058] Process the data format of the current three-dimensional cardiac electrophysiological map into DICOM RT format to obtain the process three-dimensional cardiac electrophysiological map;
[0059] Acquiring multiple cardiac cross-sectional images in the current cardiac cross-sectional three-dimensional image set;
[0060] Using the registration method based on point-line-surface geometric feature constraints, the process 3D cardiac electrophysiological map and multiple cardiac cross-sectional images are processed to obtain a preliminary 3D model of the heart. In the registration operation, the 3D coordinates of the process 3D cardiac electr...
