Mammary gland X-ray imaging exposure dose adjustment method

Abstract

The invention provides a mammary gland X-ray imaging exposure dose adjustment method. The method includes the following steps: training a plurality of mammary gland type classifiers based on a training image set, wherein the training image set includes a plurality of mammary gland pre-exposure images, each of the mammary gland pre-exposure images includes at least mark information, image information, and physical information, dividing the training image set into a plurality of mammary gland type training image sets based on the marker information, calculating the target image feature values ofeach mammary gland type training image set, collecting a pre-exposure image of the mammary gland, extracting image information of the acquired pre-exposure image, acquiring physical information of the mammary gland, inputting the extracted image information and the acquired physical information into a plurality of breast type classifiers to determine the type of breast to which the pre-exposure image is acquired, calculating a pre-exposure image feature value of the acquired pre-exposure image, according to the pre-exposed image feature value of the acquired pre-exposure image and the targetimage feature value of the training image set corresponding to the mammary gland type as a reference, adjusting the formal exposure dose. The present invention also provides a computer-readable storage medium for performing the above method.

Description

Technical field [0001] The invention relates to a mammography X-ray imaging method based on image processing technology, in particular to a method for adjusting the exposure dose of mammography X-ray imaging. Background technique [0002] According to the characteristics of the breast, the breast can be divided into multi-glandular breast, normal breast and fatty breast. In order to enable patients to receive less exposure dose radiation and obtain higher quality images, a pre-exposure plus formal exposure is usually used. Pre-exposure usually uses a dose lower than the official exposure dose, such as a dose of about 0.25 times the official exposure dose, to shoot the breast. Usually, the technician will adjust the final official exposure dose according to the shooting effect of the pre-exposure. The judgment of the effect of the pre-exposure image and the classification of the breast type are the main decisive factors for setting the official exposure dose. However, the accura...

AI Technical Summary

Problems solved by technology

Therefore, the physical information mentioned above, such as the pressure on the breast, the thickness of the gland under the current pressure, and other information will have an impact on breast imaging

That is, the image feature value is easily affected by the operator and the inspected person, so only analyzing the image feature value as the basis for adjusting the official exposure dose cannot meet the requirements
