Abstract

The invention discloses an image definition measuring device and method for a medical display. The image definition measuring device is mainly composed of three modules, namely an image generation module, an optical transfer function tester module, that is an MTF tester module, and an upper computer software module; the upper computer software module is respectively connected with the image generation module and the MTF tester module; and the image generation module mainly comprises an image processing unit, a communication unit and a control unit, wherein the control unit is respectively connected with the image processing unit and the communication unit. The image definition measuring device has the following advantages: the image definition of the pixel level of a medical display panelis quantitatively measured in a numerical value mode through an MTF, so that important reference basis and data support are provided for the objective evaluation and accurate measurement of the display definition of the medical display; the scientificity of the medical display image definition measurement efficiency and the evaluation basis is improved, and unnecessary measurement errors such as human factors are avoided; and the automation degree is high, the deployment is flexible, the maintenance is easy, and the operation is simple.

Description

Technical field [0001] The invention relates to an image clarity measuring device and method for medical displays, and belongs to the technical field of medical displays. Background technique [0002] In recent years, the digitalization of medical imaging has accelerated: on the one hand, imaging systems such as CT, MRI, ultrasound (us), and digital X-ray photography have achieved direct digitization; on the other hand, with the development of Radiological Information System (RIS) and hospitals The networked information system (Hospital Information System, HIS) is connected in parallel to form a medical image storage and transmission system (Picture Archiving and Communication System, PACS). These advanced technologies make "soft reading film" possible. As a display terminal, a medical display has become an important visualization device for doctors to perform medical imaging diagnosis. [0003] At the same time, digital image processing technology has been rapidly developed, and...
