AI Technical Summary

Technical Problem

CBCT images have problems with low contrast, high noise and fuzzy details in the surrounding areas of the target area, which affects the accurate outline of tumors and the formulation of radiotherapy plans.

Method used

By acquiring the planned CT images and CBCT images, the surrounding images of the target area are extracted after registration, and the high-frequency information is removed using the CNN deep learning network model based on the pyramid structure, the predicted theoretical low-frequency information is output, and the training is repeated by adjusting the model parameters until the requirements are met. Finally, the model is used in the radiotherapy system to enhance the surrounding images of the target area.

Benefits of technology

The quality of CBCT images is significantly improved, especially the signal-to-noise ratio in the area around the target area, avoiding additional image features or artifacts, providing a more accurate radiotherapy plan, and improving the treatment effect and diagnostic accuracy.

Abstract

The present invention discloses a method, device, equipment and storage medium for enhancing the characteristics of a target area surrounding image, including: obtaining a plurality of planned CT images and CBCT images; registering the planned CT images with the CBCT images; obtaining a target area surrounding image GTV based on the registered planned CT images and CBCT images CT and GTV CBCT ; GTV CT Subtract GTV CBCT The image after the image is used as the input image to the deep learning network model for training. The deep learning network model outputs the predicted theoretical low-frequency information GTV LowFreq ; Then get the predicted target area surrounding image GTV syn According to GTV syn With GTV CT The difference between the two is used to optimize the deep learning network model; the trained deep learning network model is applied in the radiotherapy system. The present invention significantly improves the quality of CBCT images, especially the signal-to-noise ratio of the area around the target area.
