What are the advantages of digital DR Over traditional X-ray machine ?
What is digital DR? Digital DR, referred to as DR, is an advanced X-ray photography technology formed by the combination of computer digital image processing technology and X-ray radiation technology. On the basis of the original diagnostic X-ray machine direct film imaging, it uses flat panel detector through A/D conversion and D/A conversion, real-time image digital processing, and then makes the image digitized.
So what are the advantages of digital DR Over traditional X-ray machines? Compared with traditional screen-type X-ray machines, digital DR Has higher sensitivity, low noise, digital images, etc., and specific technical advantages are as follows:
1. DR Ball tube with collimator, a large number of scattered lines will be absorbed, low ionizing radiation, only 1/20 ~ 1/30 of the traditional irradiation, reduce the X-ray damage to medical staff and patients.
2. Improve the success rate of diagnosis. Due to its high spatial resolution, time resolution and large dynamic range, digital DR Can clearly display the fine structure of various anatomical parts, and its powerful post-processing function can process images in various setting modes, so it can obtain images with clear and perfect contrast.
3. Greatly improve the work efficiency. Digital DR Adopts direct digital photography, imaging can be done after 6s exposure, and after 10s of transmission and storage, it can be immediately called by clinical workstation, the call time is 2~4s, the whole front side of the chest from photography to imaging generally takes 2min, while CR scanning time in digital processing requires 70s. It takes 6 minutes to complete the whole process, while conventional X-ray machines take much longer. Therefore, the digital DR Can handle multiple patients per day, and can send immediate reports, which greatly facilitates the patient and eliminates the complicated flushing process in the past.
4. The traditional X-ray machine is not conducive to the processing and preservation of image information, while the digital DR Provides a digital platform for the hospital network, with the standard DICOM transmission, storage, printing, file management by the computer, film comes with itself, digital images can be stored for a long time, without the past borrowing X-ray film work.
5. Digital DR Can also help patients implement remote image transmission and remote network consultation.
