LOCATING NEEDLE USED IN SYNCHRONOUS DETECTION OF CT AND MRI

摘要

A locating needle used in the synchronous detection of CT and MRI includes a silicone tube (1) and a guide needle (2) provided in the silicone tube (1). Both sides of the guide needle (2) are provided with cavities (3), and membranes (5) are provided in the cavities (3) for separating the cavities into several chambers (6) which are filled with liquids. The chambers (6) on one side of the guide needle (2) are filled with CT contrast agents, and the chambers (6) on the other side of the guide needle (2) are filled with MRI contrast agents. The locating needle is used for the detection of implantation in vivo, and the different imaging data and pathological data are synchronously compared by multiplanar reconstruction technology.
