与针孔和准直器相比，编码孔径相机具有提高信噪比（SNR）的潜在优势。这一优势可以用来提高传统成像仪的分辨率，同时仍然产生清晰的图像。本文在现有伽玛相机的基础上，设计了一种视场为9 x 9 cm、系统分辨率为1.7 mm的近场编码孔径相机。实验结果包括tc -99m标记化合物在小鼠体内的平面研究。
As compared to pinholes and collimators, coded aperture cameras present the potential advantage of increased signal-to-noise ratio (SNR). This advantage can be used to improve the resolution of conventional imagers while still producing clear images. In this paper, we describe a near-field coded aperture camera with a field of view of 9 x 9 cm and 1.7-mm system resolution based on the use of an existing gamma-camera. Experimental results include planar in-vivo studies of Tc-99m-labeled compounds in a mouse.
