Embodiment Construction

[0018] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. The present embodiment is based on the technical solution of the present invention and provides detailed implementation and specific operation process, but the protection scope of the invention is not limited to the following embodiments.

[0019] figure 1 It is a flowchart of the present invention, specifically comprising the following steps:

[0020] Step 1: Estimate the scalp projection area of ​​the intracranial space-occupying lesion based on the initial head imaging data such as MRI (or CT) after the onset of the patient's onset. Shave the patient's hair, and affix five markers that can be recognized by MRI (or CT), such as vitamin E capsules, in a circle within 1cm around the projection area;

[0021] Step 2: Carry out MRI (or CT) scan on the patient's head to obtain the tomographic data of the head;

[0022] Step 3: Reconstruct the tomographic ...

Abstract

The invention relates to a scalp positioning method for encephalic supratentorial space-occupying lesions. The method comprises the following steps of preliminarily estimating a scalp projection region of an encephalic supratentorial space-occupying lesion of a patient, and then sticking five identification points capable of being recognized by an imaging device to the periphery of the region; after the head of the patient is scanned by the imaging device, rebuilding scanned data to obtain a three-dimensional rebuilding image including superior sagittal sinus, the five identification points and the encephalic supratentorial space-occupying lesion; drawing a neutral position identification line from the portion between the eyebrows to the external occipital protuberance along the center line of the head of the patient; photographing a patient head axial bitplane image including the neutral position identification line and the five identification points through image fusion software; importing the three-dimensional rebuilding image into the image fusion software through a data line, and then utilizing the software for fusing the three-dimensional rebuilding image and the axial bitplane image to obtain a new fusion image; according to the new fusion image, identifying a scalp projection of the encephalic supratentorial space-occupying lesion on scalp.

Description

technical field [0001] The invention belongs to the medical field, and in particular relates to a scalp positioning method for space-occupying lesions on the intracranial tentorium. Background technique [0002] Intracranial space-occupying lesions refer to space-occupying lesions located above the tentorium of the brain, mainly including intracranial tumors, vascular lesions, and brain abscesses. The clinical manifestations are increased intracranial pressure and focal neurological impairment. as a feature. Surgical resection is the main treatment for space-occupying lesions on the intratentor, and accurate scalp positioning before surgery is crucial to the success of the surgery. At present, neurosurgeons often use computed tomography (CT) or magnetic resonance imaging (MRI) and other imaging data, combined with their own clinical experience, to locate the scalp and design the surgical incision. The error is relatively large, and the incision may need to be extended durin...
