 Essay about Pill Camera

INTRODUCTION

Before, doctors have already been diagnosing problems associated with the tiny intestine-such as cancer, ulcers and polyps-by using X-rays or educational surgery. These techniques are unpleasant and painful, being surgery. The advancement of your technology today has cause its powerful use and application for the medical field. 1 effective and purposeful putting on the advancement of technology is the process of endoscopy, which is often used to analyze and look at the conditions with the gastrointestinal tract of the patents. It has been reported that this procedure is done by inserting a great 8mm pipe through the mouth area, with a camera at one end, and images are shown on close by monitor, enabling the medics to carefully guide this down to the gullet or perhaps stomach. Yet , despite the performance of this process to identify the people, research demonstrates endoscopy is known as a pain putting process not merely for the patients, also for the doctors and nursing staff as well. From this, the evolution of the cellular capsule endoscope has emerged. Reports, that through the marvels of miniaturization, people with symptoms that suggest a possible in the gastrointestinal tract can now consume a tiny camera that will take snapshots inside the body to get a physician to gauge. The little camera, together with a light, transmission device, and battery packs called capsule cam, is definitely housed in a capsule, how big a large nutritional pill, and it is used in a procedure known as tablet endoscopy, which is non-invasive and painless way of looking into the oesophagus and small intestinal tract. Once swallowed, the capsule is propelled through the small intestine by simply peristalsis, and acquires and transmits individual abdomen, by using a recording unit worn on the belt stores the images, to get examined and received. Explanation:

Internally the capsule is made from 8 parts:

1)Optical dome

2)Lens holder

3)Lens

4)Illuminating led's

5)CMOS image messfuhler

6)Battery

7)ASIC transmitter

8)Antenna

Optical Dome:

This shape results in convenient orientation of the capsule axis along the central axis ofSmall intestine and thus helps catapult the supplement forward easily. The Optic Dome provides the Light Getting Window. Contact lens Holder:

The Lens Holder is that part of the capsule which will accommodates the lens. The lens can be tightly attached to the holder so that it does not get whenever.

Lens:

The Lens is usually an integral component of the tablet. It is organized behind the Light Receiving Home window. Illuminating LED's:

Around the Zoom lens & CMOS Image Sensor, four LED's (Light Giving out Diodes) are present. These multiple lighting devices are established in doughnut shape. CMOS Image Sensor:

CMOS (Complementary Metal Oxide Semiconductor) Graphic Sensor is the central part of the capsule. It is extremely sensitive and produces very high quality images. It has 140Вє field of view and can find objects no more than possible. Battery pack:

Battery employed in the supplement is press button shaped and therefore are two in number while shown. Battery packs are arranged together just behind the CMOS Photo Sensor. Silver Oxide major batteries are used (Zinc/Alkaline Electrolyte/Silver Oxide). Such a battery has a possibly discharge volt quality, disposable and doesn't harm the body ASIC Transmitter:

The ASIC (Application Specific Included Circuit) Transmission device is established behind the Batteries because shown. Two Transmitting Electrodes are connected to the outlines of the ASIC Transmitter. These electrodes are electrically isolated by each other. Antenna:

As demonstrated, the Antennae is organized at the end of the capsule. It can be enclosed in a dome shaped chamber

System components

Patients starting capsule endoscopy bear a great antenna mixture, worn in standard places over the abdominal. The recording system to which the leads will be attached is capable of saving the thousands of images sent by the capsule. A typical pills endoscopy evaluation takes about 7 several hours. Mainly you will discover 3 platform...
