The invention relates to the technical field of
interventional therapy evaluation, in particular to an in-vitro model for evaluating the accuracy of liver
interventional therapy based on DSA images, which comprises an operation track acquisition module, a spatial offset judgment module, a damage grading statistics module, a path
consistency analysis module and an efficiency grouping archiving module. Through multi-channel sensing monitoring and three-dimensional path synchronous recording, data archiving is carried out on operation actions, space changes and tissue responses in the
catheter advancing process, through comparison of path tracks and space nodes, the deviation trend is dynamically recognized, puncture
risk distribution is reflected through tissue trigger distribution and damage level collection, and the accuracy of the
catheter advancing process is improved. According to the method, indexing classification of the puncture process is constructed, further grouping is performed according to the track
goodness of fit and efficiency, space tracing and hierarchical filing of the whole operation process are achieved, damage statistics and efficiency classification contents are enriched, the space tracking capability of the whole operation process and three-dimensional display of process data are improved, and
clinical training evaluation is more accurate.
