The radiation dose of X-ray arm fluoroscopy to patients is about 1 microsievert; The radiation dose of X-ray dental film or palm examination is 5 microsieverts; The primary radiation dose of x-ray chest film is 20 microvolts; The radiation dose of mammography to patients is about 3000 microsieverts.
A person's natural background radiation dose in normal years is about 3500 microsieverts, and it is no problem to have medical X-rays occasionally. The lowest radiation dose known to affect cancer is about 65,438+0,000,000 microsieverts.
Let's learn more about DX detection:
DR is digital radiography. This is digital shooting.
The patient images taken by DR need to be sent out through the network, such as diagnostic platform and equipment for printing films. The medical network transmission protocol is called DICOM.
DX is a mode of DICOM image transmission. In the mode, there are DX CR RF XA, etc., where DX corresponds to the image of DR. The image in DX mode contains not only the gray level of the image, the patient's name, age and other information, but also the body position information (such as whether the patient stands forward or left when taking pictures). The image mode taken by CR is CR, which does not contain body position information. Of course, if the image taken by DR does not need body position information, it can also be simplified as CR mode transmission.
