Maintenance of imaging equipment is a very important part of the management of all medical imaging centers.
To assess the oldness and capacity of radiography and ultrasound equipment in Tehran University of Medical Sciences.
The study was performed in 16 hospitals, 4 faculties and three healthcare centers of Tehran University of Medical Sciences. We evaluated all the X-ray equipment (including the simple plain and dental, panorex, mammography, fluoroscopy and C-arm X-Ray devices) and also simple and Doppler ultrasound machines in terms of the type and usage of the device, production year, quantity of utilization, location, brand and current condition.
Among fixed X-ray systems, 15 were currently in use, two were junk, two were damaged, and one was not utilized. The mean (SD) of the usage of these was 2151 (2230) cliché/month, and the mean (SD) of the oldness was 16.9 (13.6) years. The oldness of radiography equipment in our study was more than 20 years in 16, between 11 and 20 in 46, and less than 10 years in 76 devices. The mean (SD) usage (patients/month) of simple and color Doppler devices were 234.1 (365.2) and 597.5 (505.3), respectively. The oldness of ultrasonography equipment in our study was more than 11 years in 12 and less than 10 years in 55 devices. We found that 22 (15.9%) of the radiography systems and two (3%) of the ultrasonography systems had been used for more than 20 years.
Radiology equipment in Tehran University of Medical Sciences have potential capacity, but they need repair, and better maintenance and management and application of standards for the imaging system needs organized supervisory mechanisms.
成像设备的维护是所有医学影像中心管理的重要组成部分。
评估德黑兰医科大学放射摄影和超声设备的使用年限及性能。
本研究在德黑兰医科大学的16家医院、4个学院和3个医疗中心进行。我们从设备类型及用途、生产年份、使用量、位置、品牌和现状等方面，对所有X射线设备（包括普通平片和牙科、全景片、乳腺摄影、透视和C形臂X射线设备）以及普通和多普勒超声设备进行了评估。
在固定X射线系统中，目前有15台在使用，2台报废，2台损坏未使用，1台未启用。这些设备的月均使用量（标准差）为2151（2230）次成像/月，平均使用年限（标准差）为16.9（13.6）年。在我们的研究中，16台放射摄影设备使用年限超过20年，46台在11至20年之间，76台少于10年。普通和彩色多普勒设备的月均使用量（患者/月）分别为234.1（365.2）和597.5（505.3）。在我们的研究中，12台超声设备使用年限超过11年，55台少于10年。我们发现，22台（15.9%）放射摄影系统和2台（3%）超声系统使用年限超过20年。
德黑兰医科大学的放射设备有一定性能，但需要维修，且成像系统需要更好的维护管理，应用标准需要有组织的监督机制。
