At the same time, within hospital there are a large number
of medical equipment such as ultrasound, CT, radiology
equipment, monitoring equipment, anesthesia equipment etc.,
producing a large number of data of different storage forms and
encoding methods. Information classification and data
standards are not of strictly uniform. Although there are
interfaces among different systems, it is very difficult to realize
the integration between various subsystems. Therefore it
directly causes the information unable to be shared effectively
among different hospitals, even between different departments
in the same hospital, thus resulting in duplication and waste of
resources.
