The feasibility of wireless portable teleradiology and facsimile (fax) transmission using a pocket cellular phone and a notebook computer to obtain immediate access to consultants at any location was studied. Modems specially designed for data and fax communication via cellular systems were employed to provide a data communication interface between the cellular phone and the notebook computer. Computed tomography (CT) scans, X-rays, and electrocardiograms (ECGs) were transmitted to a wireless unit to measure performance characteristics. Data transmission rates ranged from 520 to 1100 bytes per second. Typical image transmission times ranged from 1 to 10 minutes; however, using joint photographic experts group or fractal image compression methods would shorten typical transmission times to less than one minute. This study showed that wireless teleradiology and fax over cellular communication systems are feasible with current technology. Routine immediate cellular faxing of ECGs to cardiologists may expedite thrombolytic therapy decisions in questionable cases. Routine immediate teleradiology of CT scans may reduce operation room preparation times in severe head trauma.
本研究探讨了使用便携式移动电话和笔记本电脑进行无线便携式远程放射学及传真传输，以便在任何地点都能立即联系到会诊专家的可行性。专门设计用于通过蜂窝系统进行数据和传真通信的调制解调器，被用于在移动电话和笔记本电脑之间提供数据通信接口。计算机断层扫描（CT）、X线及心电图（ECG）被传输至一个无线装置以测量性能特征。数据传输速率在每秒520至1100字节之间。典型的图像传输时间为1至10分钟；然而，使用联合图像专家组或分形图像压缩方法可将典型传输时间缩短至1分钟以内。本研究表明，利用当前技术，通过蜂窝通信系统进行无线远程放射学及传真传输是可行的。在可疑病例中，将心电图常规即时蜂窝传真给心脏病专家可能会加快溶栓治疗决策。对严重颅脑外伤患者，CT扫描的常规即时远程放射学检查可能会缩短手术室准备时间。
