Document Type and Number:

WIPO Patent Application WO/2019/047820

Kind Code:

A1

Abstract:

An image display method, device and system for minimally invasive endoscopic surgical navigation, the image display method comprising: acquiring a CT image (S101); registering the CT image and the position and pose of a patient (S102); acquiring the position and the direction of the top end of an endoscope in a real time manner (S103); obtaining the relative position between the endoscope and the body of the patient and the distance between the endoscope and a surgical target according to the position and the direction of the top end of the endoscope and the registered CT image (S104); orthogonally cutting the registered CT image in the directions which are parallel to and perpendicular to the endoscope according to the position and the direction of the top end of the endoscope and the distance between the endoscope and the surgical target, and performing differential rendering on the orthogonally cut data on the basis of a distance weighted ray projection method (S105); and displaying a view of the relative position between the endoscope and the body of the patient, and an orthogonally cut view (S106). The image display device and system both use said image display method, realizing the image display in a surgical navigation process.
