Abstract

The invention provides a SUV (standard uptake value) based intensity modulated radiation therapy monitoring system and method. The system comprises image processing equipment, computer equipment and display equipment. The image processing equipment is used for acquiring a to-be-monitored PET-CT image and transmitting the acquired image to the computer equipment. The computer equipment is used fordetermining a target area and a critical organ on the PET-CT image, setting planned active marrow constraint conditions, generating an objective function according to the constraint conditions and a SUV of the image and optimizing the objective function according to an optimization algorithm, and an optimization result is an active marrow dose volume histogram obtained under the condition that active marrow dose is guaranteed against exceeding clinical dose limit. The display equipment displays the optimization result namely the active marrow dose volume histogram. The system has the advantagethat by embedding of the SUV into the objective function of intensity modulated radiation therapy, aimed protection of active marrow or killing of high-activity tumors can be realized.

Description

technical field [0001] The present disclosure relates to the technical field of monitoring, in particular to an intensity-modulated radiotherapy monitoring system and method based on SUV values. Background technique [0002] At present, in the design of radiotherapy plan, radiotherapists first outline the anatomical structure of the target area and organs at risk, and then apply CT images reflecting the anatomical structure for simulated positioning, plan optimization, and dose calculation. However, CT images represent density values ​​in different gray scales, which reflect the degree of absorption of X-rays by organs and tissues, but cannot reflect the distribution of active bone marrow in bones. The emergence of functional molecular imaging has given researchers the opportunity to observe the distribution of active bone marrow in patients. In recent years, researchers have used 18F-FLT PET imaging to study the distribution of pelvic active bone marrow, and conducted a co...
