Quality Control for dental Panoramic X-ray Unit Machine
口腔全景X射线机是口腔医学重要的诊断设备，它的质量控制有着非常重要的意义。本文对口腔全景X射线机的计量质量控制进行了一些探索，主要介绍了辐射剂量、半值层、空间分辨力、低对比度分辨力、管电压、曝光时间等技术参数的质量控制方法。为适应口腔全景X射线机的成像特点，设计了“U”型低对比度分辨力模体。
The quality control of the dental panoramic X-ray machine is of great significance as it is an important diagnostic device in stomatology medical domain. Some explorations to measure quality control of the dental panoramic X-ray machine are carried out. This paper mainly introduces quality control methods of some technical parameters, such as radiation dose, the half-value layer, spatial resolution, low-contrast resolution, tube voltage and exposure ti…查看全部>>
