Problems solved by technology

[0002] At first, surgeons could only rely on all the relevant information of the patient before the operation (such as: computerized tomography images) to determine the location to be operated on. For example: bone nailing) makes the patient's body move a little, causing the position of the follow-up operation to be shifted, which in turn affects the accuracy of the operation
[0003] However, at present, when surgeons want to accurately determine the position to be operated on during the operation, they must take computed tomography during the operation. absorbing too much radiation dose

Embodiment Construction

[0037] Before the present invention is described in detail, it should be noted that in the following description, similar components are designated by the same reference numerals.

[0038] see figure 1 , to execute a computer device 1 of an embodiment of the medical image alignment method of the present invention, and an ultrasonic image capturing device 2 electrically connected to the computer device 1 .

[0039] The computer device 1 includes a storage module 11 , an input module 12 , a display module 13 , and a processing module 14 electrically connected to the storage module 11 , the input module 12 and the display module 13 .

[0040] The storage module 11 stores a plurality of Computed Tomography (CT) images respectively related to a plurality of different parts of a patient's skeleton. It is worth noting that, for example, the patient's skeleton is a vertebra, the vertebra includes a plurality of vertebral segments, each vertebral segment can be divided into a pluralit...

Abstract

A medical image alignment method for image alignment of an ultrasound image with one of a plurality of computed tomography images related to different parts of a patient's bone, the ultrasound image being related to the patient one of said plurality of different parts of the bone, and implemented by a computer device, and comprising: (A) obtaining an ultrasound target image of the ultrasound image; (B) for each computed tomography image, Obtaining a scan image to be compared of the computed tomography image; (C) for each scan image to be compared, obtaining a similarity between the scan image to be compared and the ultrasonic target image; (D) from the scan image to be compared In comparing the scanned images, a pair of target scanned images corresponding to the highest similarity is obtained; (E) performing image alignment on the ultrasonic target image and the target scanned image. During the operation, the surgeon can be assisted in real-time to determine the location to be operated.

Description

technical field [0001] The invention relates to an image alignment method, in particular to an image alignment method suitable for medical images. Background technique [0002] In the earliest days, the surgeon could only rely on all the relevant information of the patient before the operation (for example, computed tomography images) to determine the location to be operated on. For example: nailing) makes the patient's body move a little, causing the position of the subsequent operation to be shifted, which in turn affects the correctness of the operation. [0003] However, at present, when the surgeon wants to accurately determine the location to be operated on during the operation, he has to take a computed tomography during the operation to determine it. However, this method cannot detect the error caused by the patient's movement in real time, which makes the patient more difficult. Absorb excessive radiation doses. [0004] In view of this, how to provide a method fo...
