CR and CT there are differences are:
1, technology is different:
Cr is the first digital technology for radiography. It is computerized digital image processing technology and X-ray radiation technology combined with the formation of an advanced X-ray machine.CT is a kind of electronic computer tomography, which uses precise collimated X-ray beams and highly sensitive detectors to scan a section of the human body around a certain part of a section and a section.
2. Safety is different:
CR digital images require less X-ray dose than traditional film imaging, so high resolution images with low X-ray dose can be obtained.CT digital images require more X-ray dose than traditional film imaging, so more X-ray dose is required to obtain high resolution images. It also exposes the patient to an increased risk of X-ray radiation.
3, the advantages are different:
CR high resolution, clear and detailed images, users can carry out a variety of image post-processing, such as digital subtraction, in order to obtain the desired diagnostic results.CT scanning time is fast, clear images.
