Abstract

The invention discloses an image display method, a device and a system for transanal endoscopic microsurgery navigation. The image display method comprises the following steps of acquiring a CT imageand acquiring an endoscope image in real time; acquiring the position and the direction of the top end of an endoscope in real time; according to the position and the direction of the top end of the endoscope, performing the cube cutting on the CT image to obtain cut cube data; based on a distance-weighted light projection method, subjecting the cut cube data to differential rendering to obtain rendered cube data; subjecting the rendered cube data and the endoscope image to virtual-real fusion treatment to obtain a virtual-real fusion image; and displaying the image. The image display device and the system adopt the above image display method, wherein the image display in the operation navigation process is achieved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an image display method, device and system for endoscopic minimally invasive surgery navigation. Background technique [0002] Due to the deep location of skull base tumors and the complex and difficult to distinguish adjacent structures, and the diagnosis and treatment process involves multidisciplinary techniques such as neurosurgery, otolaryngology, and head and neck surgery, it is difficult to completely remove the tumor. After more than a hundred years of development, the diagnosis and treatment of skull base tumors has evolved from naked-eye craniotomy to endoscopic minimally invasive surgery. The endoscopic minimally invasive technique is simple in operation and quick in postoperative recovery. Guided by endoscopic images, it can avoid the damage of the surgical approach to the facial skin structure, thereby reducing the probability of various complications. [0003] At ...
