Mammography is a radiological diagnostic method which relies on an X-ray examination of breasts and is a process involving the use of low-dose amplitude-X-rays (usually around 0.7 mSv). Combining the use of small doses and high quality images requires extensive quality protocols, part of them being included in regulations adopted by the Minister of Health.
The aim of this study was to check the usefulness and efficacy of selected quality tests associated with mammography.
MATERIAL/METHODS: The study was performed in the mammography service of the Greater Poland Cancer Centre in Poznan. Following equipment was used: densitometer, sensitometer, mammographic scales, electronic scales, thermometer, hygrometer, PMMA plates, Europhantom, screen film contact phantom, viewing boxes and magnifying glasses. The methods were based on basic mammography tests. Quality control in mammography demands: clean darkroom, marked and clean cassettes, clean viewing boxes with homogenous light.
The results of the "Development Process" test show that each sensitometer has to be used with an appropriate densitometer. Phantoms with abnormal structures cannot be used to "AEC System - Solidity exposure" test. "Compression - The force of compression" test may only be carried out with suitable scales and compressible material. Analysis of rejected films shows that the main reasons for rejection were wrong collimation and underexposure.
Every quality control in mammography provides essential information about the functioning of a laboratory. Apart from recommended standard sterility, it should be remembered that equipment should always be adjusted and repaired.
乳腺钼靶摄影是一种依靠乳房X线检查的放射诊断方法，是一个使用低剂量振幅X射线（通常约0.7毫希沃特）的过程。结合小剂量使用和高质量图像需要广泛的质量协议，其中部分协议包含在卫生部通过的法规中。
本研究的目的是检验与乳腺钼靶摄影相关的选定质量检测的有用性和有效性。
材料/方法：该研究在波兹南大波兰癌症中心的乳腺钼靶摄影科室进行。使用了以下设备：密度计、感光计、乳腺摄影标尺、电子秤、温度计、湿度计、有机玻璃平板、欧洲体模、增感屏 - 胶片接触体模、观片箱和放大镜。这些方法基于基本的乳腺钼靶摄影检测。乳腺钼靶摄影中的质量控制要求：清洁的暗室、有标记且清洁的暗盒、有均匀光线的清洁观片箱。
“显影过程”检测结果表明，每个感光计都必须与合适的密度计配合使用。具有异常结构的体模不能用于“AEC系统 - 实体曝光”检测。“压迫 - 压迫力”检测只能使用合适的标尺和可压缩材料进行。对被拒收胶片的分析表明，拒收的主要原因是准直错误和曝光不足。
乳腺钼靶摄影中的每项质量控制都提供了有关实验室运行的重要信息。除了推荐的标准无菌要求外，还应记住设备应始终进行调整和维修。
