Abstract

The invention provides a centerline extraction method. The method comprises the steps that a spine image is provided; an intervertebral disk point and a head and neck joint point in the spine image are detected based on a classification device; and the intervertebral disk centerline of the spine image is extracted based on the intervertebral disk point and the head and neck joint point. According to the invention, the classification device is used to detect the intervertebral disk and the head and neck joint point of the spine image; regional growth is carried out on a detection result probability graph to calculate a communication domain to acquire the intervertebral disk point; intervertebral disk center point and centerline are calculated based on a spine fit line and the detection probability graph; the classification device is used to directly detect the intervertebral disk; spinal block detection is not before intervertebral disk positioning; and errors caused by splitting is avoided.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a centerline extraction method. Background technique [0002] Magnetic resonance MR examination is becoming more and more popular due to its characteristics of non-invasive, arbitrary cross-section and multi-parameter imaging, especially in the clinical application of central nervous system and spine. Generally, in order to facilitate diagnosis, when performing MR spine imaging, the scanning plane is usually set to be parallel to the direction of the centerline of the target intervertebral disc. This is because MR imaging is non-isotropic, with higher resolution in the scan plane than between scan planes. Therefore, by aligning the scanning plane with the center line of each intervertebral disc, the influence of the secondary feature information of the spine can be removed, and the image information of the spine and the intervertebral disc can be obtained accurately and c...
