Peripheral arterial disease (PAD) has been increasing in Japan. In the case of severe PAD, surgical treatment is generally performed. Accurate grasp of the cut site is very important in securing the patient's QOL. Transcutaneous oxygen partial pressure (TcpO2) measurement is a well-established technique for existing PAD treatment, but it has some problems. We have already constructed a system to visualize the blood flow dynamics of the back and bottom of the toe. However, in a subsequent basic study of this system for PAD patients, it became clear that involuntary movements affected image processing. Therefore, the purpose of this research is to develop a blood flow dynamics visualization system that removes motion artifacts using a toe fixture and non-rigid registration. An evaluation experiment was performed with the developed system, and it was reported that the artifact on the image associated with the release of the avascularization was reduced.
