Method for processing scalp positioning images of brain tumors

Abstract

The invention discloses a method for processing scalp positioning images of brain tumors, which comprises the following steps of: (1) preliminarily estimating a scalp projected area of a brain tumor of a patient, adhering two mark points which can be identified by an imaging device in the area, obtaining a two-dimensional medical image slice set from the imaging device, and reconstructing a three-dimensional profile of a scalp layer; (2) manually drawing a profile line of the tumor on a two-dimensional image, and reconstructing the surface of the tumor; (3) determining the positions of the two mark points on the two-dimensional image, and reconstructing the mark points; and (4) rotating a profile image of the reconstructed three-dimensional profile image to an appropriate position, and then printing the image in an equal proportion. Compared with the prior art, the method disclosed by the invention is implemented simply; and when the method is applied to the positioning of a brain tumor, the positioning precision meets the demands of tumor resection through a craniotomy, the shortening of operation time and the reduction of surgical traumas are facilitated, and the incision length can be minimized under the premise of guaranteeing good exposures.

Description

Technical field [0001] The invention relates to an image processing method, in particular to a brain tumor scalp positioning image processing method. Background technique [0002] Scalp positioning of brain tumors is an important step before craniotomy, and the accuracy of positioning directly affects the quality of surgery. At present, brain surgeons usually only design craniotomy incisions and remove tumors based on the tumor information shown in CT, MRI and other imaging data, and rely on clinical experience. Because the exact location of the tumor cannot be determined before the operation, a larger incision is often required, and sometimes due to inaccurate positioning, the incision may need to be extended during the operation. Stereotactic headgear or neuronavigation system can accurately locate brain tumors, and can correctly guide the direction and depth of the surgical approach, but it is expensive and cumbersome to operate, and is not suitable for small and medium hospi...
