Problems solved by technology

The image quality assurance system in the prior art may have the following defects: the detection technology for the misalignment problem does not consider adopting a special image quality standard, and the detection technology for the poor exposure problem may depend on the exposure index Or rely on global or local histogram analysis, but it does not consider whether the body part, tissue or bone structure of DR imaging is identifiable
However, technicians at the image acquisition end cannot get timely feedback to adjust the image acquisition solution

Embodiment Construction

[0025] In the following description, more specific details are set forth in order to provide a thorough understanding of the invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without these specific details. In the present invention, specific numerical references such as "first element", "second means" and the like are made. However, specific numerical references should not be construed as necessarily obeying their literal order, but rather should be construed as different "first element" from "second element".

[0026] The specific details set forth herein are exemplary only, and the specific details may vary while remaining within the spirit and scope of the invention. The term "coupled" is defined to mean either directly connected to a component or indirectly connected to a component via another component.

[0027] In the present invention, the X-ray image is a digitized image obtained by a flat panel dete...

Abstract

The invention relates to an X-ray image quality control system. The X-ray image quality control system includes: an image acquisition unit configured to acquire an X-ray image and determine a type of an imaging site and a type of a projection mode; and a quality detection unit which is configured to detect image defects in the X-ray image according to the type of the imaging part and / or the type of the projection mode. The quality control system can effectively identify image problems including inaccurate positioning, patient movement, external object artifacts, poor exposure and the like, can provide feedback to technicians at image acquisition points, and is beneficial to timely adjustment of an image acquisition solution.

Description

technical field [0001] The present invention relates to the technical field of digital X-ray photography, and more particularly relates to an X-ray image quality control system. Background technique [0002] In digital radiography, some poor quality images are rejected. Causes may include mispositioning of the imaging site, patient movement, artifacts, and poor exposure. Among them, setup errors can be divided into two types: center positioning errors and errors caused by wrong projections (eg camera rotation). Setup errors can also include errors due to the part to be imaged not being fully imaged (or blocked, truncated). [0003] The quality control of X-ray images (such as DR images or CR images) is usually implemented based on the visual observation of technicians, which has certain subjectivity. Some image quality defects are more obvious, such as necklace shadows (which block the view of the chest or spine) or visual truncation of soft tissue areas of the knee; some...
