What are the similarities and differences between the examination techniques of soft radiography and conventional radiography? Differences in their clinical applications

The following are the similarities and differences between soft radiography and conventional radiography:

Similarities:

1. The principle is the same: both soft radiography and conventional radiography utilize X-rays to penetrate an object to produce an image for examination.

2. Similarity in equipment: Both require the use of an X-ray emitting device and a detection device to operate.

Differences:

1. Radiation Dose: Soft X-rays use a low dose of radiation while conventional X-rays use a high dose of radiation. The radiation dose of soft radiography is comparatively lower, which reduces the radiation damage to the patient.

2. Software processing: Soft X-rays use image-processing software to enhance and adjust the image to obtain clearer details. Conventional radiography uses less software processing.

3. Resolution: Soft X-rays have a higher resolution and can show organs and subtle lesions more accurately. Conventional radiography has a relatively low resolution.

4. Scope of examination: Soft X-ray is mainly used for the examination of organs such as the breast, lungs and bones. Conventional radiography is used to examine all parts of the body.

Difference in clinical application:

Soft X-ray is mainly used for screening and early diagnosis of breast cancer, which can reduce unnecessary biopsy surgery and improve the early detection rate. Conventional radiography, on the other hand, is widely used for the diagnosis and evaluation of various diseases, such as lung infections, bone fractures, and chest masses.
