A Canberra hospital has unveiled technology that allows surgeons to control high-tech imaging technology with voice commands.

The Little Company of Mary Health Care has invested $500,000 installing the iSuite technology into a theatre at Calvary John James Private Hospital.

Hospital chief executive Shaun Gillespie says the ceiling-mounted monitors are hands-free and will help to reduce theatre delays and improve surgery accuracy.

"They are at the highest pixelation and picture quality," he said.

"The detail is very precise and they can have better vision of where they are operating.

"It will decrease the set-up time for theatres. It could decrease set-up times by about 30 minutes.

"The surgeon could command the video to commence recording. They can tell the video to stop recording, it can then dim the light."

The technology also ensures surgical teams have instant access to vital patient information and diagnostic results.

It allows for information such as digital radiography, CT scans and and pathology results to be sent directly to theatre monitors for the surgeon's viewing.

Mr Gillespie says the hospital collaborated with the medical company that manufactures the technology.

"This equipment enables us to keep pace with the rest of the world by providing our surgeons with the best possible images and continues the high quality of care provided to our patients at Calvary John James Hospital," he said.

The hospital plans to install the technology in another of its theatres in April 2014.
