A, instrument and equipment name Direct Digital Imaging System (DR) Second, the reasons for the purchase
1, the current state of the radiology equipment in our hospital
My hospital is using a 300 mA X-ray machine has been nearly two decades, the equipment is obsolete, work faults are frequent, has been repaired many times, the quality of the film image is poor, now, although the addition of (the provincial Department of supporting the issuance of) A new X-ray machine, but the film image quality is only general, and the staff operation process is cumbersome, low work efficiency, workload, causing great inconvenience to the clinical diagnosis, with the improvement of the quality of life of the people, the equipment required for the examination of the requirements of a higher, clearer image quality requirements, in order to improve the diagnostic imaging technology and efficiency of the hospital, it is necessary to update the diagnostic radiology equipment of our hospitals, direct digital imaging (DR) system is the current state of the art in our country, the image quality is more clear. Direct Digital Imaging (DR) system is the most advanced digital diagnostic imaging equipment in China, which has completely solved the digitalization problem in conventional radiological imaging information processing, enabling the examiner to obtain diagnostic reports from the registration to a one-time completion of the diagnostic report, improving the diagnostic quality, shortening the time of the examination, reducing the previous intermediate work links, improving the efficiency of the work, and can comprehensively satisfy the needs of the examined person, which embodies the concept of humanized service of medical imaging. The concept of humanization of medical imaging services.
2, and traditional X-ray imaging, direct digital imaging system (DR) advantages:
(1) rapid imaging, fast workflow, high efficiency. Digital imaging to obtain image data for 0.125 seconds, eliminating the darkroom link (loading, washing, etc.) in the casting of photographs, can be a large number of consecutive checkups of patients, outpatient examination reports can be completed in a faster time.
(2) electronic storage medical imaging. Digital imaging can use CD-ROM storage, management information, can be transmitted remotely medical images, improve the hospital remote consultation ability. At the same time to find information is very convenient, fast, so that the radiology department to get rid of the film as the carrier of the image and the medium to store the image data.
(3) excellent image quality. Digital imaging can be window width window position adjustment, edge enhancement, gray scale transformation and a series of post-processing techniques, no waste film. It saves the trouble of checking again when the quality of many previous images does not meet the diagnostic requirements.
(4) Low radiation dose. Radiation dose can be greatly reduced, especially suitable for children, pregnant women, old and frail and need to check the patient.
3 (5) Easy diagnosis. Higher density resolution and increased diagnostic information through post-imaging processing, measurement, tissue equalization, energy subtraction, etc..
Three, the prospect of technological development of the proposed equipment
Direct digital imaging system (DR) is booming because it can directly create images that have a digital format. It is considered more competitive than CR systems, it has better spatial resolution and contrast than CR systems, the patient receives a smaller dose of radiation due to improved X-ray photon conversion efficiency (DQE), and most importantly, the workflow of radiologic techniques is greatly improved. In order to achieve higher efficiency, DR must be integrated into the PACS system. Direct digital imaging system (DR), fundamentally changed the acquisition, display, storage, exchange of medical images and means. Completely replace the film, showing an attractive prospect. Computer-based medical image storage and communication system PACS, is a breakthrough into the hospital hall of fame. Direct digital imaging system DR, as a key link in PACS, as a revolutionary symbol of the imaging department, has become the preferred choice of hospitals.
Four, the acquisition of the source of funding
The hospital to take the staff to raise funds for the purchase of shares. V. Price and quantity
The hospital intends to purchase a direct digital imaging system (DR), about 600,000 yuan to be purchased VI. Economic benefit analysis
The hospital examines an average of about 20 patients per day, according to the national standard of 70 yuan per person, the annual income of about 504,000 yuan, less than two years to recover the cost of equipment purchases.
VII, the required supporting facilities
1, housing layout, water and electricity facilities to meet the requirements of 2, spare parts, consumables sources can meet 3, sewage, radiation can be resolved 4, supporting facilities to meet the requirements of VIII, the basic situation of personnel
Our hospital radiology department has a clinician, skilled, are in Changde City, a hospital in the Department of Radiology, a formal training for one year, and obtained Radiology staff post certificate. (Issue date July 1, 2011 City Health Bureau released)
