移动式伽玛闪烁照相机的出现,增加了核医学对各种病人的诊断功效。有些病人不能走到备有核医学设备的地方去,所以往往不能受检查。较常见的有急性和(忄万)性心脏病患者、疑有肺栓塞的患者、肾移植患者以及依赖人工呼吸器生存的患者。移动式伽玛闪烁照相机的诞生,对于病人和操作方法带来了新的有利条件。虽然在设有心脏科的急救医院中配备这样一台装置费用很大,但还是值得的。本文报导的移动式伽玛照相机其图象质量与目前通用的固定式伽玛照相机差不多或者还要好一些。本照相机不作为移动式装置使用时,亦可以在核医学检验室内作为固定式照相机使用。
The advent of mobile gamma scintillation cameras has added nuclear medicine’s diagnostic power to a variety of patients. Some patients can not go to the place where they have nuclear medicine equipment and therefore often can not be inspected. More common are acute and (10,000) patients with cardiac disease, suspected pulmonary embolism, kidney transplant patients and those who rely on respirators survival. The birth of the mobile gamma scintillation camera has brought new advantages to patients and methods of operation. While it would be expensive to equip such a device in a cardiology emergency hospital, it is still worth it. The image quality of the mobile gamma camera reported in this paper is about the same or better than the currently available fixed gamma camera. This camera can also be used as a stationary camera in a nuclear medicine laboratory when it is not used as a mobile device.
