Abstract
Modulation transfer function (MTF) was used in comparing the visual outcome units of gamma camera. Polaroid camera system and Micro Dot imager were studied using Polaroid film type 105 positive/negative and Kodak SO-179 X-ray film. It was proved that resolution in the Micro Dot imager is better than in the Polaroid camera system used, especially near the surface of the measuring object.
摘要
调制传递函数（MTF）被用于比较γ相机的视觉输出单元。使用宝丽来105正/负型胶片和柯达SO-179 X射线胶片对宝丽来相机系统和微点成像仪进行了研究。结果表明，微点成像仪的分辨率优于所用的宝丽来相机系统，尤其是在测量对象表面附近。
