[0004] However, in the above-mentioned double exposure method based on the average gray scale, the average gray scale only reflects the overall information of the image without considering the details of the mammary gland. Therefore, the exposure image taken at the official exposure time t2 cannot make the The most important part of the gland presents good image quality

Embodiment Construction

[0060] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0061] At present, mammography equipment can automatically set exposure parameters according to the specific conditions of the patient (such as breast thickness, etc.). The exposure parameters mainly include the tube voltage, tube current and exposure time of the tube. Among them, when setting the exposure time according to the breast conditions of di...

Abstract

The invention discloses an exposure method for a mammary gland machine device, and the mammary gland machine device. The method comprises the steps of performing pre-exposure on to-be-exposed mammarygland to obtain a pre-exposure image; taking the pre-exposure image as an object image, calculating a gradient magnitude mean value of a gland part in the object image, and calculating a percentage ofa first gland point set in a second gland point set, wherein the first gland point set comprises all pixel points of the gland part in the object image, and the second gland point set comprises all pixel points of a mammary gland region in the object image; and according to the gradient magnitude mean value and the percentage corresponding to the pre-exposure image, determining formal exposure time of the to-be-exposed mammary gland. The characteristics of the mammary gland are considered when the formal exposure time is set, so that when the to-be-exposed mammary gland is exposed by adoptingthe formal exposure time, the gland part in a formal exposure image can present relatively high image quality.

Description

technical field [0001] The present application relates to the technical field of medical imaging, and in particular to an exposure method of mammary gland machine equipment and mammary gland machine equipment. Background technique [0002] In the traditional exposure technology of the digital mammography machine, the doctor will determine the exposure parameters according to the actual condition of the patient's body and subjective experience, and manually set the exposure parameters. The exposure parameters include the tube voltage and tube current of the tube of the digital mammography machine. and exposure time. Since the exposure parameters set completely depend on the subjective experience of the doctor, the requirements for the experience and level of the doctor are too high, and they are too subjective, lacking a scientific and objective theoretical basis, resulting in poor quality and stability of the exposure image. In order to avoid the above defects, the automati...
