Measurement of blood vessel movement for induction of micro object with US therapy planning software

Abstract

The purpose of this study is to create a therapeutic plan on human body to induce a micro object through blood vessel considering of human body. First, based on the image analysis of 3D blood vessel network, the system calculates the possible area ultrasonic transducers with respect to shape of the body surface and the position of ribs using an optical positon sensor. Next, by applying 2D-3D registration in echogram, 3 dimensional blood vessel movement is acquired using body surface, rib positon and blood vessel movement. We created a therapeutic plan to guide a thin catheter, where 2D-3Dregistration of human liver was performed. As the result, we suggested the usefulness of the therapy planning software.
