Introduction to Medical Display Solutions


Advances in the technology of optical displays have changed the way surgeons are able to manage different illnesses. Minimally invasive surgery encompasses a wide range of endoscopic procedures, whereby the body cavity (abdomen, thorax, gastrointestinal tract, and joint spaces) is accessed through small incisions and the use of telescopes and fine, long instruments.

These techniques have rapidly gained in popularity during the last decades, as patients are experiencing less discomfort after surgery. Visualization of the operative field requires optimal image capture, processing, and display.

The introduction of charge-coupled devices has enabled surgeons to view the operative field on a video monitor, allowing ever-more-complex operations to be performed endoscopically. However, limitations include loss of 3-D perception and tactile sense, poor ergonomics, often suboptimal positioning of the image display and image quality that is too dependent on outside influences. These limitations, and possible solutions, are addressed as the “ideal” system for endoscopic surgery. 

Best image with LCD: Recently, flatpanel liquid crystal display (LCD) monitors have provided an improved image quality at a reduced price, and may operating rooms are now replacing CRT monitors with flatpanel displays. Their light weight, versality, and small footprint allow the use of multiple screens placed near the operating table.

While LCD monitors produce the best image and have a greater portability than CRT monitors, the positioning of the screen is still limited by a number of factors, including the need to keep the immediate surroundings of the operative field sterile and the presence of a large number of instruments, instrument tables, cables, and other equipment that add to the clutter of the endoscopic operating theatre.

(Here in Singapore, many hospitals such as Mt. E in Orchard has been enjoying the benefits of LCD in their clinics).
