What are the similarities and differences between soft X-ray photography and conventional X-ray photography? The difference of its clinical application

The inspection techniques of soft X-ray photography and conventional X-ray photography have the following similarities and differences:

Similarities and differences:

1. The principle is the same: both soft radiography and conventional radiography use X-rays to penetrate objects to produce images for inspection.

2. The equipment is similar: both of them need to use X-ray emitting devices and detection devices for operation.

Difference:

1. radiation dose: soft x-ray photography uses low dose radiation, while conventional x-ray photography uses high dose radiation. The radiation dose of soft X-ray photography is relatively low, which can reduce the harm of radiation to patients.

2. Software processing: Soft X-ray photography uses image processing software to enhance and adjust the image to obtain clearer image details. Traditional X-ray photography is seldom processed by software.

3. Resolution: Soft X-ray photography has higher resolution and can display organs and subtle lesions more accurately. The resolution of conventional X-ray photography is relatively low.

4. Scope of examination: Soft X-ray photography is mainly used for the examination of breast, lung, bone and other organs. Traditional X-ray photography is suitable for examination of all parts of the body.

Differences in clinical application:

Soft X-ray photography is mainly used for screening and early diagnosis of breast cancer, which can reduce unnecessary biopsy operations and improve the early detection rate. Conventional X-ray photography is widely used in the diagnosis and evaluation of various diseases, such as lung infection, fracture and chest mass.
