放射图像的即时传输对于急诊患者的快速临床决策可能是重要的。我们研究了以内置摄像头的个人数字助理（PDA）电话为基础的即时图像传输系统。显示在图像存档和通信系统（PACS）监视器上的图像可以被PDA电话中的摄像头直接捕获。然后，图像可以通过无线高带宽网络（CDMA 1 x EVDO）从急救中心传送给远程医生。我们回顾了通过计算机断层扫描（CT）、磁共振成像（MR）和数字血管造影等方式产生的10例正常和10例异常病例的放射学病变。图像深度为24位，像素为1144 × 880、1120 × 840、1024 × 768、800 × 600、640 × 480和320 × 240。三名神经外科医生发现，要获得满意的远程会诊，CT和MR图像的最小尺寸为640 x 480像素，血管造影图像的最小尺寸为1024 x 768像素。虽然分辨率越高，临床满意度越高，但传输时间也越长。在有限的带宽下，更高的分辨率是不合理的。
The instant transmission of radiological images may be important for making rapid clinical decisions about emergency patients. We have examined an instant image transfer system based on a personal digital assistant (PDA) phone with a built-in camera. Images displayed on a picture archiving and communication systems (PACS) monitor can be captured by the camera in the PDA phone directly. Images can then be transmitted from an emergency centre to a remote physician via a wireless high-bandwidth network (CDMA 1 x EVDO). We reviewed the radiological lesions in 10 normal and 10 abnormal cases produced by modalities such as computerized tomography (CT), magnetic resonance (MR) and digital angiography. The images were of 24-bit depth and 1144 x 880, 1120 x 840, 1024 x 768, 800 x 600, 640 x 480 and 320 x 240 pixels. Three neurosurgeons found that for satisfactory remote consultation a minimum size of 640 x 480 pixels was required for CT and MR images and 1024 x 768 pixels for angiography images. Although higher resolution produced higher clinical satisfaction, it also required more transmission time. At the limited bandwidth employed, higher resolutions could not be justified.
