DR as the current mainstream X-ray film development trend, has become a hospital radiology department must have one of the "weapons", and domestic and foreign production of DR manufacturers up to 40 to 50 manufacturers, the products are mixed, the quality of varying, the level of each high and low. So how do we in the many manufacturers of DR products in the eyes of the pearl, to find a truly suitable for the actual situation of our hospital products? I think we can argue and examine from the following aspects.
1, the overall evaluation criteria
DR's real mission is to ensure the quality of the image under the premise of changing the workflow of the flat film, improve work efficiency; the user's evaluation of the equipment should also be based on this, taking into account the equipment's maintainability, the failure rate, the price, the overall cost and the cost of maintenance of the latter and other practical factors. Therefore, the purchase of DR, the need for a comprehensive overall evaluation, not for the manufacturers of some imported components or a single technical indicators or a term and confused; to consider the company's production and R & D strength, image quality, efficiency, after-sales service and other aspects.
1)R&D Strength
Even if the same hardware is used for a product, the equipment produced by different manufacturers is very different. Due to the special nature of medical equipment, determines the high quality of medical equipment for hospitals is a kind of protection, not only to solve the clinical application of hospitals, hospitals to create economic benefits, and the importance of diagnostic equipment is self-evident. The strength of production and research and development determines the stability of the product, and the stability of the product is critical to the hospital. Thus, when purchasing equipment, you should understand whether it is a professional manufacturer of DR equipment, its R & D history, R & D team, the standardization of the production plant, the product listing time, the degree of autonomy of the entire machine, whether to master the core technology rather than random assembly. Products on the market certainly need to go through the market test, continuous improvement, but for the user, if you spend hundreds of thousands of dollars or even millions of dollars from unprofessional companies to buy an immature product, in the end is to buy to use? Or buy to repair? The risk is unquestionable.
2)Image quality
High-quality and stable imaging quality is one of the original purposes of purchasing DR equipment, but also to improve the level of diagnosis and treatment of the physical basis. It involves radiographic signal-to-noise ratio, resolution, clarity, contrast, detail display and other aspects, mainly by the detector technology, the quality of the bulb tube X-rays, post-processing functions, the compatibility of the hardware and computer operating software to determine.
3)Efficiency
Reducing labor intensity, change the workflow to improve efficiency is one of the most important functions of the DR, but also the acquisition of such equipment is an important reference; involves the dynamic range, imaging speed, data transmission/processing speed, and so on; because of the omission of many unnecessary work procedures, the normal rate of output should be the traditional screen/glue system of 2-3 times. The normal output rate should be 2-3 times that of a conventional screen/gel system.
4) after-sales service
Requirements for timely and complete, as far as possible, choose the provincial capital of the city has offices and after-sales maintenance branch of the professional manufacturers, before the acquisition of the technology and brand differences must be considered to bring differences in the quality of after-sales service, as far as possible, choose the domestic and foreign recognized major manufacturers of mainstream mature products. Amorphous selenium flat-panel DR due to the immaturity of its technology leads to high maintenance frequency is a factor that must be considered before the acquisition.
2, the actual demand
To meet the actual needs of the hospital room as a starting point, the overall performance and image quality of the equipment and the use of cost, after-sales service. The main factors are: the size of the hospital, the influence of the local community, specialty departments, the amount of film size, budget and so on. If the hospital has high technical requirements, outpatient filming volume, sufficient funds, it is recommended to choose amorphous silicon flat-panel DR; if the cost-effective requirements are very high, it is strongly recommended that the CCD DR, all the types of DR, it is the lowest price, in the case of not wanting to spend too much money on the hope of buying a DR, the CCD DR must be the first choice, due to the charges for all types of DR is the same.
