Abstract

The invention discloses a three-dimensional navigation method of a bronchial endoscope. The method comprises the following steps of reading multi-mode medical tomographic image data; generating a virtual three-dimensional model from the multi-mode medical tomographic image data; calculating virtual coordinates and virtual directions; carrying out comparison according to an actual position image and a virtual position image, adjusting the coordinate values of the virtual coordinates and the direction values of the virtual observation directions; performing Gaussian function attenuation on the edges of real-time images of the endoscope and performing fusion with a virtual scene view of the endoscope. The method solves the technical problems of poor medical image imaging quality, low precision and non-ideal navigation effect in operation navigation in the prior art.

Description

technical field [0001] The invention relates to the field of endoscopes, in particular to a three-dimensional navigation method for bronchial endoscopes. Background technique [0002] Generally, the location of bronchial disease is relatively deep, and the structure of the lesion is complicated and difficult to distinguish. At present, bronchial surgery generally adopts endoscopic minimally invasive surgery. Endoscopic minimally invasive surgery is simple in operation and quick in postoperative recovery. Guided by endoscopic images, the damage to the structure of the bronchus is avoided by the surgical approach, which greatly reduces the risk of various complications. probability of a complication occurring. [0003] However, medical images in surgical navigation are not accurate in terms of the relative position, distance, and direction between surgical instruments and the human body, and the navigation effect is not ideal; single-mode medical images have single organizati...
