Issue 147 The Tricorder August 21, 2013

If you have ever watched Star Trek then you will know of the tricorder. For those who do not know, the tricorder is a futuristic device meant to take readings on various phenomena. So it could be used to scan for people and other life forms in an area, radioactive material, various minerals and elements along with energy signatures. But the most important version was the medical tricorder. And you know what? The medical tricorder may just become reality.

Behind the scenes: The "X Prize" program has set up another one of their contests to make the tricorder real. "X Prize" is a foundation where a person or business puts up money as a prize for creating a successful invention. In this case a tricorder. The contest rules dictate that the "tricorder" must be able to perform 3 medical functions. With the contest open toward everyone, ideas were a plenty. In fact the successes at the contest have led to interesting innovations.

Results: Some of the tricorder designs were not tricorders in looks of Star Trek, but smart phones with additional functions. One version had an attachment that allowed it to perform a sonogram. Another was able to monitor for a person's vital signs like their heart beat. There was even one that could monitor a person’s blood sugar for diabetes patients (it had a mechanism that allowed the test strips to be inserted). This got many people thinking about how the smart phone can be a true to life tricorder. Other types spawned from the ideas of the "X Prize" teams were an App that acted in the same way as Web MD allowing you to help diagnose your own medical issues. Currently in Africa, a smart phone equipped with a blood sample reader can test for malaria and a few other diseases like dengue fever. Smart phones are becoming a common tool for people to help themselves diagnose themselves or doctors to have access to cheap alternatives to medical equipment. The perfect example of this is the sonogram function which costs $300 as opposed to the one thousand plus dollar pieces of equipment already in service. Also in the works is a smart phone that not only monitors vitals, but has a test tube you spit in. This tube has test strips to test for certain chemicals which only show up when you are sick. So the device will also be able to test for a multitude of deceases at the same time. The result may be a true tricorder.

What to expect: The technology is actually in its infancy. As computers get smarter and are able to store more memory along with processing power they will be able to do more. It will not be surprising to find a doctor taking out his smart phone to help diagnose his/her patients. On top of that, the doctor will be able to send prescriptions based on the diagnosis (which may be aided by, or even done by the smart phone itself). Already doctors are using digitized records with ipads and tablet PCs to save on cost and also to email prescriptions, but with a "tricorder" it may become a whole lot easier to do. For instance doctors do not always know of what new drugs are on the market. But with the "tricorder" they will have access to all the information on all the drugs that will help heal their patient. In fact, they will be able to see which drugs and treatments will be covered by their patients insurance and at what cost. However, patients may take on a greater role in treating themselves for minor things like small colds and fevers. This will disturb some doctors, but that has become the goal for some of the innovators behind real life tricorders. These people want individuals to save time and money by being able to treat themselves when and where they can. Mean while doctors are hesitant about being replaced by a computer. Yes the tricorder will be capable of doing much more with far little cost, but development and approval by agencies such as the Food and Drug Administration (FDA) are slow. So our neighbors in Africa and other nations with not so strict regulations will get to use this technology first.

Conclusion: Tricorders, or tricked out smart phones, are going to be the future of medicine. The goal of creating the ultimate medical muti-tool as seen on Star Trek is just too tempting to pass up given all its advantages. So the real question is how long it will be before your doctor is using one. As a matter of fact, it is a question of how long until you can buy one for your self.
