Problems solved by technology

If the exposure dose is adjusted based on the grayscale of a specific part of the human body detected by traditional image processing algorithms, it will be difficult to quickly obtain a more reasonable exposure dose, resulting in poor imaging quality and possibly causing patients to receive unnecessary radiation doses

Abstract

The invention provides an exposure dose adjustment method and system. The method includes obtaining a first image according to a first exposure dose; inputting the first image to a detection model, and determining the region of interest in the first image, the detection model being a machine learning model; determining a gray value of the region of interest in the first image; and adjusting the first exposure dose according to the gray value and a preset gray target value, and obtaining a second exposure dose used for generating a second image. Thus, high-quality images with proper exposure doses can be rapidly obtained, and unnecessary radiation doses received by patients can be effectively reduced.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to an exposure dose adjustment method and system. Background technique [0002] The automatic exposure dose adjustment in medical imaging technology can automatically adjust the dose according to the patient's position, the patient's fat and thin, and the part to be photographed, so as to not only ensure the image quality, but also protect the patient from unnecessary X-ray exposure. The automatic exposure dose adjustment technology adjusts the exposure dose of the next frame according to the calculated grayscale of the human body area in the current image. A specific part of the human body (eg, bones, lungs) detected based on traditional image processing algorithms may contain non-human tissues (eg, implants) or directly exposed areas (eg, air). If the exposure dose is adjusted based on the grayscale of a specific part of the human body detected by traditional ...
