For advanced gastrointestinal stromal tumour (GIST) patients who are responding to imatinib mesylate, the role of surgery has not been formally demonstrated. This multicenter randomised controlled trial was designed to assess whether surgery to treat residual disease for patients with recurrent/metastatic GISTs responding to imatinib mesylate (IM) improved progression free survival (PFS) compared...
In this paper, the collision detection and response that based on the OBB (oriented bounding boxes) tree structure was realized in virtual surgery simulation system for nasopharyngeal carcinoma. The point of contact location and the vector of contact surface can be acquired. The force effect in virtual surgery simulation was improved. A twice detection method was proposed to improve the phenomenon...
With the development of computer technology, Virtual Surgery Simulation (VSS) becomes into reality. Virtual surgery is multi-disciplined and challenged. There have been some open source resources for VSS but they are all in progress. A new open source based VSS system is presented. An object oriented system analysis and design are described in detail including use case diagram, sequence diagrams,...
