Abstract The advanced technology of computing system
was followed by the rapid improvement of medical instrumentation
and patient record management system. The typical
examples are hospital information system (HIS) and picture
archiving and communication system (PACS), which computerized
the management procedure of medical records and
images in hospital. Because these systems were built and used
in hospitals, doctors out of hospital have problems to access
them immediately on emergent cases. To solve these problems,
this paper addressed the realization of system that could
transmit the images acquired by medical imaging systems in
hospital to the remote doctors’ handheld PDA’s using CDMA
cellular phone network. The system consists of server and
PDA. The server was developed to manage the accounts of
doctors and patients and allocate the patient images to each
doctor. The PDA was developed to display patient images
through remote server connection. To authenticate the
personal user, remote data access (RDA) method was used
in PDA accessing the server database and file transfer protocol
(FTP) was used to download patient images from the remove
server. In laboratory experiments, it was calculated to take
ninety seconds to transmit thirty images with 832×488
resolution and 24 bit depth and 0.37 Mb size. This result
showed that the developed system has no problems for remote
doctors to receive and review the patient images immediately
on emergent cases.
