Method, system, device, and medium for calculating average gland dose of mammography system

Abstract

The invention discloses a method, a system, a device, and a medium for calculating the average gland dose of a mammography system. The method comprises the steps of: introducing an incident dose lookup table and an air kerma lookup table; obtaining an exposure voltage value KV, a current time product mAs, a gland compression thickness Thinkness, and a distance SID from a flat panel detector to a radiation source; searching a corresponding incident dose value EntranceDose and a corresponding air kerma value HVL from the incident dose lookup table and the air kerma lookup table; determining a dose conversion factor g and a correction factor c of the gland component; determining a correction factor s of the filtered combination; calculating the average gland dose AGD. According to the method,the system, the device, and the medium for calculating the average gland dose of a mammography system, the incident dose value and the air kerma value can be obtained quickly through the lookup tables, and the average gland dose value can be calculated according to the dose conversion factor, the correction factor of the gland component, and the correction factor of the filtered combination, so that the method, the system, the device, and the medium have the characteristics of rapid calculation, can ensure that the total average dosage does not exceed the guidance level, and is suitable for aconventional digital mammography system.

Description

technical field

[0001] The invention relates to the field of medical detection, in particular to a method, system, device and medium for calculating the average gland dose of a mammography system. Background technique

[0002] As one of the important issues of women's health, mammary gland has been paid more and more attention by people. In recent years, the incidence of breast cancer has been increasing year by year in my country, especially in many big cities, breast cancer has become the most common malignant tumor in women, which seriously threatens women's health. Studies have shown that if breast cancer can be detected early, its cure rate will be greatly improved, so early diagnosis of breast cancer has very important clinical value. The actual clinical discovery of breast cancer early shows that there are tiny calcifications in the breast. These tiny calcifications are difficult to find when using ultrasound imaging, and the use of digital mammography to examine the...
