Problems solved by technology

[0004] However, when there are multiple centerline segments that need to be corrected (that is, the segments to be corrected), the existing centerline correction methods need to be corrected segment by segment, and even need to be combined with the centerline segmentation module to correct each segment segment by segment. The connection sequence between segments, etc., the whole correction process is complicated and time-consuming, which cannot meet the clinical needs for rapid acquisition of the colon centerline

Embodiment 1

[0027] The colon centerline editing method provided in this embodiment is applicable to the centerline correction after the colon centerline is automatically extracted. The method can be performed by a colon centerline editing device, which can be implemented in the form of software and / or hardware, and which can be integrated in equipment with data computing functions, such as desktop computers or servers, etc., especially in medical in computer equipment. see figure 1 , the method of this embodiment specifically includes the following steps:

[0028] S110. Determine at least one segment to be corrected in the initial centerline according to the initial control point set and the correction point set corresponding to the initial centerline.

[0029] Wherein, the initial control point set refers to a set composed of points (ie, control points) that control the direction of the centerline of the colon, which is obtained from the initial centerline. The initial set of control ...

The explanations of terms that are the same as or corresponding to the above-mentioned embodiments will not be repeated here. see figure 2 , the colon centerline editing method provided in this embodiment includes:

[0045] S210. Determine at least one segment to be corrected in the initial centerline according to the initial control point set and the correction point set corresponding to the initial centerline.

[0046] S220. If the correction point subset corresponding to the segment to be corrected contains less than or equal to the preset number of correction points, determine the first initial control point subset corresponding to the segment to be corrected as the segmental control point set corresponding to the segment to be corr...

Embodiment 3

[0069] On the basis of the first embodiment above, this embodiment further optimizes "generating the target centerline point set according to the target control point set and the initial control point set". The explanations of terms that are the same as or corresponding to the above-mentioned embodiments will not be repeated here. see image 3 , the colon centerline editing method provided in this embodiment includes:

[0070] S310. Determine at least one segment to be corrected in the initial centerline according to the initial control point set and the correction point set corresponding to the initial centerline.

[0071] S320. Based on the correction point subset corresponding to the segment to be corrected, a target control point set is generated based on a level set algorithm.

[0072] S330. If the initial centerline includes a centerline segment, use the target control point set as the modified control point set.

[0073] Wherein, the modified control point set refers...

Abstract

The embodiment of the invention discloses a colon centerline correction method, device, equipment and storage medium. The method includes: according to the initial control point set and the correction point set corresponding to the initial centerline, determining at least one segment to be corrected in the initial centerline; according to the correction point subset corresponding to the segment to be corrected, based on the level set An algorithm is used to generate a target control point set; and to generate a target centerline point set according to the target control point set and the initial control point set. Through the above-mentioned technical solution, it is realized that the entire colon centerline can be corrected correctly and quickly through one human-computer interaction, which greatly improves the convenience of colon centerline correction.

Description

technical field [0001] Embodiments of the present invention relate to medical image processing technology, and in particular to a colon centerline correction method, device, equipment and storage medium. Background technique [0002] When using a virtual colonoscope for colon inspection, the centerline of the colon is used as the navigation path of the colonoscope "roaming", so the correctness of the colon centerline is very important. [0003] The current processing of the colon centerline can be roughly divided into two parts: automatic centerline extraction and centerline correction. Among them, the results of the automatic extraction of the central line depend on pre-treatments such as bowel cleansing, oral enhancer, and inflation before scanning the patient. If the pre-processing is insufficient, it will cause the automatically extracted initial center line to be divided into several independent center line segments and the connection direction between each center line...
