Problems solved by technology
[0004] At present, most manufacturers lack a scientific selection and evaluation plan, and often only complete the compatibility test of key components, but do not evaluate the impact of different key components on image quality, which makes the key components often selected unsatisfactory.
For example, some manufacturers blindly pursue low prices when selecting models, and introduce key components with low performance, which makes the original image quality drop sharply; Image quality improvement isn't huge
This makes it difficult to choose a set of cost-effective key components, and even if a technician has made a good selection plan through experience, due to the lack of scientific quantitative evaluation and no repeatability, once it needs to be replaced In the absence of experienced guidance, the selection of core components will become very difficult

Embodiment Construction
[0076] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0077] In order to quantify the effect of key component selection on image quality, the present invention designs a special-purpose prosthesis module for evaluation, such as figure 1 shown.
[0078] It consists of the following parts:
[0079] Part 1: 20cm * 20cm * 10cm PMMA prosthesis;
[0080] Part 2: line pair measurement module with resolutions of 3LP / mm, 3.5LP / mm, and 3.7LP / mm, module size is 10mm * 10mm;
[0081] Component No. 3: 10mm*10mm*0.5mm aluminum sheet with a 4mm*4mm*0.2mm hollowed out area in the center;
[0082] Part 4: 10mm * 10mm * 2mm aluminum sheet, with a hollow area of 4mm * 4mm * 0.2mm in the center;
[0083] Part 5: 4mm * 4mm * 0.5mm aluminum sheet;
[0084] Part No. 6: 5mm * 5mm lead cross star positioning mark.
[0085] Among them, the No. 1 component is used to simulate the thickness of human tissue, which can be use...

The invention relates to an apparatus and a method for selecting key parts of digital radiographic image equipment. The method comprises the design of a prosthesis specifically for evaluation and an automatic detection algorithm matching the prosthesis. The method comprises following steps: 1, designing the prosthesis specifically for evaluation; 2, shooting the prosthesis for many times so as to acquire evaluation image sequences; 3, performing evaluation through the automatic detection algorithm matching the prosthesis, and 4, acquiring all evaluation indexes. The invention provides the apparatus and method for selecting key parts for an X-ray image equipment producer. Evaluation index reports of all selection schemes can be acquired through the prosthesis specifically for evaluation and the automatic detection algorithm, and the comparison between evaluation results of the selection schemes can be carried out. The apparatus and method can assist the producer in scientifically evaluating the selection schemes, so that the optimal key part selection scheme can be obtained.
Description
technical field [0001] The invention specifically relates to a device and method for selecting key components of digital radiographic imaging equipment. The present invention mainly provides a scientific, repeatable and comparable device and method for the selection of key components of digital X-ray imaging equipment. By adopting this method, manufacturers of digital X-ray imaging equipment can obtain scientific selection of their key components. guidance recommendations. Background technique [0002] At present, the vast majority of digital X-ray imaging equipment manufacturers adopt the production method of integrated assembly, that is, they select components from different manufacturers and assemble them into their own branded machines after passing the integration test. Therefore, the selection of key components will directly affect the quality of images collected by digital X-ray imaging equipment. At present, various manufacturers rely on their own image post-proces...
