WIPO Patent Application WO/2021/065956
Kind Code:
A1
Abstract:
An imaging system according to the present disclosure comprises an imaging catheter, at least two measurement devices, and a control device. The imaging catheter includes an outer sheath, an imaging sensor including an imaging probe, a shaft, and three position sensors. The control device includes a coordinate specifying unit that specifies, on the basis of position information of the three position sensors measured by the at least two measurement devices, three-dimensional coordinates of each point in a plurality of tomographic images of the biomedical tissue generated on the basis of biological structure information acquired from the imaging sensor. The three position sensors include: two position sensors arranged at different positions in the central axis direction of the shaft; and one position sensor disposed at a position different from that of one of the two position sensors in a circumferential direction of the shaft.
