Raspberry Pi technology powers cutting-edge advances in a variety of fields.One recent example involves development in endoscopy.
Endoscopic camera-based technology allowsdoctors to see abody’s internal organs by insertinga camera into the body. This water-resistant miniature camera makes it possible to view the body’s internal organs without the needfor a potentially risky operation.
TheNeed for anAlternative toTraditionalEndoscopyMethods
Although endoscopy is a marvel of modern medicine, the traditional endoscopic technology has left much to be desired.
Harold H Hopkins’ invention of glass rod lenses and Karl Storz’s development of the fiber-optic cold light source were combinedto create thetraditional endoscopy method. Althoughthis method is helpful to patients, it is an expensive option,which makes it prohibitivein low-income economies and constrained environments.
In addition to the exorbitant cost,there are other aspects of the traditional technology that could be improved upon. These include:
Luckily, these drawbacks are easily overcome by the Raspberry Pi Zero endoscope camera!
Raspberry PiDeliverson What Matters
The Raspberry Pi Zero endoscope camera was developed by researchers J.M. Lazarus and M. Ncube at theUniversity of Cape Town. Theirresearch paperprovides an in-depthlook into theirentire process in developing thisnewendoscope camera.
Starting with the aimto makeendoscopy a reality in medical settings that can’t afford expensive
methods,Lazarus andNcube came up with their design.
With theirprototype, the researchersset out to replace:
And it works! Built for a mere $230,this new Raspberry Pi endoscopic camera is thousands of dollars cheaper than the traditional wired options (which typicallycost around $28,000).
NotableFeatures of the Raspberry Pi Endoscope Camera
Lightweight and portable
Weighing just 184 g, the Raspberry Pi Endoscope Camera is a lightweight and portable option that will increase the convenience of operations in medical settings.
Wireless video transmission
Wireless video transmission is made possible in close to real time and theimperceptible latency is less than 200ms.Although the zoom option is not available, the device offers good white balancing and color rendering.High-definition image quality is also made possible at 30 frames per second.
High-definition tube camera
A 1280 × 720 pixel high definition tube camera helps in the generation of the video signal that is transmitted for display onto a laptop computer.
Quality imaging forless
The Raspberry Pi poweredendoscopecamera doesn’t just deliver the same quality for a cheaper price. It actually improves quality in many aspects and offers greater convenience at a lower price point.
How did researchers manage to make it cheaper?
ResearchersLazarus and Ncubemanaged to keep the cost low at $230 by making use of theRaspAP software. Thismade possiblea wireless setup as well as a management systemtoget a wireless access point put up and quickly run it on Raspberry Pi. The Raspberry Pi can then receive camera images andtransmit them onto a display device for easy viewing.They also used the Raspberry Pi Zero W (available here at Vilros) for high-definition video.
This may just beabeginning, but it has the potential to changethefutureofmany medicaloperationsgoing forward!
