WIRELESS TELERADIOLOGY AND FAX USING CELLULAR PHONES AND NOTEBOOK PCS FOR INSTANT ACCESS TO CONSULTANTS

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 faring 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. ((C) 1995 by W.B. Saunders Company)
