Description

A radiographic projection system

technical field

The invention belongs to the technical field of medical equipment, in particular to a radiation projection system.

Background technique

The digital radiography (DR) system is widely used in the imaging department of the hospital, which generally includes an X-ray generator (also called a ball tube), a detector (or called a sampler), an acquisition console (with Image processing functions of images) and parts of mechanical devices (such as beds, arms, etc.). Among them, the detector is a key component of the DR system, which has a relatively large impact on the quality of the DR image. Different types of detectors are likely to be selected in different manufacturers or different types of DR systems.

Due to the differences in the types of detectors, the characteristics of the detectors (such as size, sensitivity, pixels, etc.) are also different, and the imaging methods of the corresponding DR systems are also different, which is reflected in the hardware or image acquisition of the acquisition console Corresponding special design and special operation are required on the software system. For example, DR systems using different types of detectors use different exposure parameters in the imaging process, and also use different image processing parameters in the image processing process. Also, different types of detectors reflect differences in their quality, and different types of detectors are suitable for different imaging applications; for example, relatively high-quality types of detectors (and relatively expensive) are suitable for pediatric diagnostic applications , a relatively low-quality type of detector (the price is relatively cheap) is suitable for adult diagnostic applications; for another example, for DR imaging of the same inspection site, the image quality of different types of detectors is different, so different inspection sites Different types of detectors are sometimes required to produce the most diagnostic images; also for example, different types of detectors have different noise patterns.
