Medical Imaging With a Hacked LCD Projector

Posted by Soulskill on Tuesday January 3, 2012 @12:20PM from the convergent-technology dept.

An anonymous reader writes "Grad students at UC Irvine have built a spatial frequency domain imaging system using parts from a cheap LCD projector and a digital camera. The system can be used to check the level of bruising or oxygenation in layers of tissue that aren't visible to the naked eye, according to an article in Chemical and Engineering News. An accompanying video shows the series of patterned pulses that the improvised imaging system makes in order to read hemoglobin and fat levels below the surface of the skin. A more sophisticated version of the imaging system is being commercialized by a startup within UC Irvine, called Modulated Imaging. The article and video also describe infrared brain scanners that can non-invasively check for brain bleeds, and multiphoton microscopes that produce stunning images of live skin cells."

  I think that is a sort-of thing. If you don't actually market it as a medical device, then it isn't regulated as a medical device. You can use 50 cent light-bulbs in a hospital room, for example. Of course, using something not certified as a medical device to make a diagnosis could subject you to liability, so there is a line to walk. Oh, and most insurers won't pay for things that aren't certified. So, if you're charging for an office visit and the doctor pulls out one of these then that wouldn't matter much, but if you're a diagnostic center and you want to bill simply for doing the scan, then forget it most likely.

It may not always be perfect, but it is based on holding companies to well-designed, well-run studies - you know, the scientific method.
  The Dalkon Shield (http://en.wikipedia.org/wiki/Dalkon_shield) was approved based on flawed studies, and was a frickin' dirt magnet, with woven strings and plenty of nooks and crannies into which bacteria could set up shop (in the normally sterile intrauterine environment), risking septic shock in users: that is, it killed not just fetuses, but moms.
  You may also recall the sad case of thalidomide (http://en.wikipedia.org/wiki/Thalidomide), in wide use throughout Europe, but denied approval by (a brave, lone) FDA staffer based on inadequate study data. We can now thank our lucky stars she did so, given limb reduction deformities that only later on were attributed to the drug (at least in its racemic form).
  There is an example of a market of pharmacologically active compounds not approved by the FDA: herbs and dietary supplements. Most of them purport to "support health" and relieve a variety of ailments, and the market is in the $US billions, but the number shown to actually work better than placebo in the sort of study the FDA uses for drugs hovers slightly above zero. In terms of what people actually use in common practice (well, my practice anyway - I'm a cheapskate family physician who sticks to older generic drugs) herbs and supplements aren't significantly cheaper. I've got quite a few sophisticated (and not so sophisticated) patients who use supplements regularly, based on thin or non-existant evidence, including a fair amount of folks who are going to die sooner (for example, by avoiding cholesterol medicine despite heart conditions) as a result of wanting to stick to "natural medicine."

  Because a hundred years ago or so the public just got fed up with all these incredibly dangerous medical devices and procedures out there, all advertised as safe by outright quacks and fraudsters and plenty of people who believed deeply that what they sold was safe. So laws were passed that medical devices and procedures need to be tested for safety. Now certainly you're allowed to build your own device that does the same thing if you want, but you can not sell the product to other people without proving that it's safe first.
  In other words, you're allowed to be unsafe to yourself but you can't be unsafe if it involves other people.
  The customers are not medical experts and so they rely on others to tell them if something is safe or not.

  Technology makes medicine and education less expensive, not more. CPUs are not simple devices, yet you can buy one for near nothing today and you can buy the most expensive ones for a fraction of a cost of any US medical bill. It takes billions of dollars to design/develop/build CPU fabs and it's still cheap at the end - because there is no government standing between the CPU manufacturer and the consumer.

The insurance company will then send an explanation of benefits which states that they will pay $800, you will pay $200, and the biller can forget about the other $7k.

  There are a lot of neat things you can do with fMRI. While in some ways they're more limited than NMRs there are a lot of neat things you can do because of the added spacial dimension. You can selectively excite stuff in one part of a subject and watch how it moves around (well, within a second or two), which is great for watching blood flow. You can also do a lot of neat stuff with Xenon isotopes (which interact with surfaces of things if you breathe them in right before having a scan done).
