Abstract

The invention discloses a target area and organ-at-risk outline sketching accuracy inspection method based on radiomics. The method comprises the following steps: acquiring a sketching contour of a target object in an image; scaling the delineated contour through different scaling sizes, and determining a difference feature of a preset scaling size according to the preset scaling size and scaling contours with different scaling sizes adjacent to the preset scaling size; establishing a first neural network model for a preset size according to the difference feature; and testing whether the sketched contour is accurate according to the first neural network model. According to the method and the device, the technical problems that the image sketching effect is poor, the accuracy and the stability are low and the sketching quality is difficult to evaluate quickly due to an image segmentation algorithm in related technologies, so that a graph sketching result needs to be artificially identified are solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a radiomics-based method for testing the accuracy of contouring of target areas and organs at risk. Background technique [0002] Image segmentation to identify organs or lesion regions from medical images (e.g., CT or MRI images) is one of the most challenging tasks in medical image analysis, which is to capture key information about the shape and volume of these organs. Many researchers have proposed various automatic segmentation systems by applying existing techniques. Older systems were built on traditional methods such as edge detection filters and mathematical methods. [0003] Machine learning methods by extracting handcrafted features have been a dominant technique for a long time. Designing and extracting these functions has been a major consideration in developing such systems, and the complexity of these approaches has been seen as a significant limitation to...
