Difference one:
From the time-consuming point of view:
Traditional X-ray machine, DR, CR efficiency compared to the traditional X-ray examination to take out the film takes 6 minutes, CR examination takes 7 minutes time, and DR is a one-time exposure is completed, its work efficiency is greatly accelerated.
Difference 2:
From the compatibility point of view:
DR is more suitable for grass-roots use because of its good compatibility.
Difference three:
From the operation aspect:
DR is easy to operate, save time and labor, and improve efficiency.
DR's advantages:
1, DR dynamic range is wide, there is a wide exposure latitude, thus allowing technical errors in the photo, even in some parts of the exposure conditions are difficult to master, but also to obtain a very good image.
2, digital X-ray DR high resolution, clear and detailed images, wide gray scale, able to obtain a large amount of information, the application of leading digital image algorithms, fully guarantee the image quality.
3, DR in the fluoroscopic state, the digital image can be displayed in real time, the doctor and then according to the patient's condition of the digital photography, and then through a series of image post-processing such as edge enhancement, magnification, black and white flip, image smoothing and other functions.
Rich and reliable clinical diagnostic information can be extracted from these images, especially for the discovery of early lesions, which can provide good diagnostic conditions.
4, DR in the work of the imaging process, radiating out of the X-ray dose than the traditional X-ray machine dose is much less, but can get a clearer image, but also reduces the amount of radiation on the medical staff and patients.
5, DR to achieve "no film" so that the hospital canceled the traditional film to record images of the management of the patient's image can be recorded in the computer, for the hospital to save the film funds, but also improve work efficiency.
6. DR can enter the hospital PACS system, which provides great convenience for hospitals to conduct remote expert consultation and online communication. In addition, TIWI's DR can display multiple images and make comparisons between images, which is conducive to accurate doctor's judgment and diagnosis.
Expanded Information:
Disadvantages of DR:
1. The use of optical conversion systems in the imaging process results in geometric distortions of the image, which can only be repaired by the use of optical components and post-processing software. components and post-processing software to fix it.
2. The X-ray dose is significantly higher than that of flat-panel DR, especially for high-resolution images of the extremities, where the X-ray dose is almost the same as that of ordinary film photography.
Lowering the X-ray dose as much as possible is one of the development directions of radiological imaging equipment, and it is obvious that the performance of CCD-DR in this regard is not satisfactory.
3, the spatial resolution is slightly lower than the ordinary flat film, the price of special equipment is expensive, and the function is limited by the grade of the computer and storage space.
