New clot finder prototype tested in India.

On a day in which we are being inundated with bad news from Virginia Tech, I thought I'd look at something good instead.  Just to be contrary.

So here it is, a portable device that they claim can image CVAs.

The device, called an "infrascanner", can spot blood clots on the surface of the brain known as haematomas, which can lead to death or disability if left untreated.

It is being tested in India, but if successful it could have benefits for patients anywhere.


The infrascanner uses harmless "near-infra-red" light - like that in a TV remote control.

The light beam penetrates the skull up to three centimetres.

A blood clot absorbs near-infra-red light differently to normal brain tissue and the signal is bounced back to the scanner.

The tech then views the results on a computer or even a PDA.  There's a picture of the whole lash up in the article.  Looks like a really sweet piece of kit, particularly for ambulances, emergency rooms and old folks homes.

The nice part is it'll be cheap enough to become wide spread in use, just like the portable defibrillator.  This will hopefully allow lots of clots to get diagnosed early enough for those miracle clot-buster drugs to have a shot at fixing up the patient.

So there you go, some good news on a bad day.
