Evolution Conventional radiology

evolved from analog images processed on standard radiographic film to digital data

Portable imaging has brought services to the bedside in the Intensive Care Unit (ICU)

Image availability in the ICU has become an electronic reality

Portable computed tomography (CT) scanner

Clinical benefit Decreases risks associated with intra-

hospital transport

Completed in approximately 20 minutes from time it was ordered

Risk in transport up

to 70%

Adverse events still

occur 15% of the time
