Accuracy is an important index of vascular interventional surgical robot system, and is influenced by the accuracies of image navigation and interventional robot, and random errors. Based on the vascular interventional surgical robot propulsive mechanism, a series of accuracy experiments are carried out, and the test results are analyzed, which validate that the propulsive mechanism satisfies the...
A new image-navigation system for vascular interventional surgery robot (VISR) is proposed. This system can provide robot with navigation information based on projection images without other external tracking devices. Firstly, projection images acquired from digital subtraction angiography (DSA) machine are calibrated by iterative optimization process. Secondly, 3D vascular model is reconstructed...
