Using Thin Clients for Medical Data
A thin client is any computer system basically, that uses an application for whom all processing occurs on a central server, with just the results shipped back to the client for sisplay. Data storage is never performed on the client machine.
This paradigm is ideal for medical data, which is of an obviously sensitive nature and not the sort of thing to be stored willy nilly on a thousand different computers around the world, as it is passed from expert to expert.
It is perhaps surprising thusly, that utilising thin clients for medical data is a very young concept, first coming in thanks to the work of Mercury Computer Systems at the very end of 2008. The company trialled the first such medical data client, which they call Visage.
In addition to keeping medical data safe and centralised, a medical thin client setup allows any number of computers, no matter their specification, to connect and manipulate data. All that is needed is the physician's access authority - which increasingly is provided by biometric data. In this way, a patient's records can be worked on on a desktop computer, laptop, palmtop, even a web enabled phone. Use can flip from device to device as the medical professional travels about, or passed to another professional on the other side of the world, instantly and easily.
Mercury's offering, is designed as a diagnostioc tool, helping to virtualise healthcare, by manipulating PACS compatible diagnostic data from a variety of sources - CAT scans, X rays, ultrasound, ECGs... In fact almost every computerised medical tool, permitting the professional to overlay data, combine data, enhance it, create 3D variants and rotate. Everything designed to give far more useful information than a 2D slice taken from any one angle, and all in real-time.
As Visage is the only such system on the market at time of writing, it is hard to compare the offerings of different systems. However, it is safe to say that this system sets the bar very high indeed. The following, taken from the company's brochure, lists the type of data that can be remotely manipulated in this manner:
