What does the tangent direction of the x line mean?

The x-line tangent direction refers to the image obtained by the x-ray penetrating the object. According to the location of a certain point in the image and the distribution of surrounding points, the tangent direction at that point can be determined. This method is widely used in the field of medical diagnosis, and doctors can judge the patient's condition through X-ray images.

In medicine, the tangential direction of x-rays is used to determine the location and scope of lesions, and can also help doctors perform surgical positioning and navigation. In addition, the x-ray tangent direction can also be used in the field of radiotherapy to determine the location of the radioactive source and the scope of radiotherapy to ensure the treatment effect and avoid damage to normal tissues.

In addition to the medical field, the x-ray tangent direction also has important applications in the industrial field. For example, in the field of material testing, X-ray images can detect defects and foreign objects inside materials to determine the quality and reliability of materials; in the field of automobile industry, X-ray images can help detect engine parts and determine whether there are defects and damage, thereby ensuring the safety and performance of the car.
