Pill Camera
INTRODUCTION
In the past, doctors have been diagnosing problems associated with the small intestine-such as cancer, ulcers and polyps-by using X-rays or exploratory surgery. These techniques are both unpleasant and painful, as is surgery.
The advancement of our technology today has lead to its effective use and application to the medical field. One effective and purposeful application of the advancement of technology is the process of endoscopy, which is used to diagnose and examine the conditions of the gastrointestinal tract of the patents. It has been reported that this process is done by inserting an 8mm tube through the mouth, with a camera at one end, and images are shown on nearby monitor, allowing the medics to carefully guide it down to the gullet or stomach.
However, despite the effectiveness of this process to diagnose the patients, research shows that endoscopy is a pain stacking process not only for the patients, but also for the doctors and nurses as well. From this, the evolution of the wireless capsule endoscope has emerged. Reports, that through the marvels of miniaturization, people with symptoms that indicate a possible in the gastrointestinal tract can now swallow a tiny camera that takes snapshots inside the body for a physician to evaluate.
The miniature camera, along with a light, transmitter, and batteries called capsule cam, is housed in a capsule, the size of a large vitamin pill, and is used in a procedure known as capsule endoscopy, which is non-invasive and painless way of looking into the oesophagus and small intestine. Once swallowed, the capsule is propelled through the small intestine by peristalsis, and acquires and transmits patient abdomen, through a recording device worn on a belt stores the images, to be examined and received. Description: Internally the capsule is made of 8 parts:
1) Optical dome
2) Lens holder
3) Lens
4) Illuminating led’s
5) CMOS image sensor
6) Battery
7) ASIC transmitter
