Problems solved by technology

[0006] Based on the above technical problems, the present invention provides a method for automatically delineating the radiotherapy target area of ​​nasal cavity NKT cell lymphoma, which solves the problem of using existing deformation registration as the delineation method due to the large individual differences between patients. It is often difficult to define a general template to meet the needs of sketching, which leads to the problem of low sketching accuracy

Abstract

The present invention relates to the technical field of medical images, and discloses a method and device for automatically delineating a radiotherapy target area of ​​nasal cavity NKT cell lymphoma, wherein the method includes: collecting a CT image of the outlined nasal cavity NKT cell lymphoma; After processing, a deep learning data set is obtained; the deep learning data set is trained in a deep neural network model to obtain a nasal NKT cell lymphoma delineation model; clinical CT images are preprocessed and input into the nasal NKT cell lymphoma delineation model for delineation. The present invention solves the problem that in the existing situation, due to large individual differences among patients, it is often difficult to define a general template to meet the needs of delineation when using the existing deformation registration as the delineation method, resulting in low delineation accuracy.

Description

technical field [0001] The invention relates to the technical field of medical images, in particular to a method and device for automatically delineating a radiotherapy target area of ​​nasal cavity NKT cell lymphoma. Background technique [0002] Nasal NK / T cell lymphoma is a more common malignant lymphoma in Asia, Latin America, and South America. It is more common in China, Japan, and South Korea in East Asia, and it often occurs in young and middle-aged men aged 30-50. Radiation therapy, referred to as radiotherapy, uses high-energy radiation to damage DNA, prompting tumor cells to stop growing and slow down their growth. Because nasal NK / T cell lymphoma is sensitive to radiotherapy and resistant to chemotherapy, radiotherapy has become one of the main treatment methods for early nasal NK / T cell lymphoma. [0003] Before patients receive radiotherapy, they need to take computed tomography (CT) images, and then radiologists outline the area containing the tumor on the CT...
