摘要
医用显示器是医疗行业使用的高清晰度、高亮度显示仪器。由于其显示的图像信息决定了诊断的准确性,因此对质控和计量的要求较高。本文针对其原理,依据JJF 1746-2019《医学影像诊断显示系统校准规范》,研制了一款便携式在线校准装置,并进行试验验证。结果表明:该装置不仅能实现最大光亮度、光亮度比、亮度均匀性、色度偏差、对比响应和可视角等技术参数的准确校准,提高校准效率,降低人为误差,而且满足校准需求,具有较高的实用价值。
Medical displays are high-definition and high brightness display instruments used in the medical industry.Due to the fact that the displayed image information determines the accuracy of diagnosis,there are high requirements for quality control and measurement.This article focuses on its principle and develops a portable online calibration device based on JF 1746-2019"Calibration Specification for Medical Imaging Diagnostic Display Systems",and conducts experimental verification.The results show that the device can not only achieve accurate calibration of technical parameters such as maximum brightness,brightness ratio,brightness uniformity,chromaticity deviation,contrast response,and viewing angle,improve calibration efficiency,reduce human error,but also meet calibration requirements and have high practical value.
