Abstract：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 time. In order to adapt to imaging characteristics of the dental panoramic X-ray machine, the ‘U’ type low-contrast resolution phantom has been designed.
