影象学器材及材料的发展是医学影象学发展的前提。随着对影象学图象质量要求提高及对辐射损伤的重视,对胶片的要求亦发生了变化。要求X线胶片既要提高高质量的图象,又要尽可能使用小剂量X线。X线感绿片可以满足这一要求。本文报道感绿X片胸部高千伏摄片密度测定与最佳观片密度。 The development of imaging materials and materials is the prerequisite for the development of medical imaging. With the increasing demand for image quality and the importance of radiation damage, the requirements for film have also changed. X-ray film requires both to improve high-quality images, but also to the extent possible, the use of low-dose X-ray. X-ray green tablets to meet this requirement. This article reports the sensory green X-ray chest high kV radiographic determination of the best density and film.
