Outline of Final Research Achievements

This study aimed to build a system for non-invasive and real-time measurement of 3D position of a patient supported by parallel and distributed computers. We constructed a non-invasive marker-less system for measuring respiratory motion at multiple points on a patient’s surface using a depth camera. Obtained respiratory phase was consistent with a signal measured by a consumer monitoring system. Computation time of a PC cluster using MPI was made 10 times faster than that of a single machine. Precision of registration was almost the same as one of a standard imaging registration software.
