Abstract

The invention discloses an organ contour line quality evaluation method, device and system. The method comprises the steps that a target image is acquired, the target image comprises a plurality of voxels, and the target image at least comprises a medical image of a target organ and a delineated contour line of the target organ; according to the contour line, a first area and a second area are determined in the target image, the first area is located on the outer side of an area surrounded by the contour line, and the second area is located on the inner side of the area surrounded by the contour line; then a first evaluation index of the target attribute of the first area and a second evaluation index of the target attribute of the second area are determined; and a quality evaluation result of the contour line is determined according to the first evaluation index and the second evaluation index, and the quality evaluation result is output. The method solves the technical problem that the accuracy of the evaluation result of the contour line is low due to insufficient local detail evaluation of the contour line due to insufficient utilization of the image attributes of the region near the contour line in the existing organ contour line quality evaluation method.

Description

technical field [0001] The present invention relates to the field of medical imaging, in particular to a method, device and system for evaluating the quality of organ contour lines. Background technique [0002] In fractionated radiotherapy, a patient's treatment plan is typically generated using planning CT prior to treatment. However, due to differences in fractionation caused by setup errors and patient anatomical variations, the plan generated before treatment may not be optimal on a given day during treatment. To visualize these changes and uncertainties, imaging techniques such as airborne cone-beam CT and magnetic resonance imaging (MRI) are routinely implemented in treatment rooms. Finer fractional change management introduces online adaptive replanning (OLAR), which uses imaging data from the day of treatment to optimize treatment planning based on real-time anatomy. [0003] Because OLAR must complete online planning while patients lie in the treatment couch wait...
