. Describe one use of optical fibres in medicine. 1 a i A ray of light passes through a length of curved optical fibre. 1 1 Describe one use of optical fibres in medicine.

You may draw a diagram. MEDICAL APPLICATIONS OF FIBER-OPTICS. Optical fibres provide a high degree of signal security as it is confined to the inside of fibre.

The Optical Regenerator Necessary for long-distance data transmission. You may draw a diagram. Describe one use of optical fibres in medicine.

UCLES 2016 06_0625_41_2016_110 12 3 Light travels down optic fibres into or out of body To examine internal organ part Light travels both ways into and out of body OR To destroy cancerous cells by heating OR Endoscope fibre bundle inserted into body. 1 a A ray of light passes through a length of curved optical fibre. 1 1 Describe one use of optical fibres in medicine.

Optical fibres are used in a number of instruments that enable doctors to view internal body parts without having to perform surgery. Optical fibres are used in endoscopes that allow surgeons to see inside their patients. To destroy cancerous cells by heating.

They can be made in extremely thin flexible strands for insertion into the blood vessels lungs and other hollow parts of the body. You may draw a diagram. Optical fiber sees growth as medical sensors.

Draw a diagram showing the fibre and the path of the ray of light. They are flexible and very high tensile strength. The flexible yet rigid multifibers enable visualization of internal organs and tissue via bodily orifices.

The intrinsic physical characteristics of optical fiber combined with its versatility in remote sensing make it an attractive technology for biomedical applications. 1 ii Describe one use of optical fibres in medicine. Draw a diagram showing the fibre and the path of the ray of light.

You may draw a diagram. Optical fibers allow doctors to make visual analysis and treatment of various diseases through very small incisions using an endoscope. The light in the optical fibre has a wavelength of 32 x 10 7m and is travelling at a speed of 19 x 108ms.

I Calculate the frequency of the light. Optical fibres are of small size and have lightweight as compared to electrical cables. Flexible and rigid multifibers composed of step-index fibers and graded-index imaging rods are extensively used for visualization of internal organs and tissue which are accessible through natural openings or transcutaneously.

An endoscope is a medical instrument made to insert two optical fiber bundles into one long tube. Which one of these is not a type of electromagnetic wave. Draw a diagram showing the fibre and the path of the ray of light.

Medical use of optical fibres Optical fibres are often used in medical procedures. The Optical Receiver It receives the transmitted light pulse signal and decodes them to be fit to use. You may draw a diagram.

1 ii Describe one use of optical fibres in medicine. Thus they can be twisted and bent easily. If you were to see the end of the endoscope this is what you would see.

7 a i A ray of light passes through a length of curved optical fibre. The most significant and prevalent applications of fiber optics in medicine are in the imaging and illumination components of endoscopes. The endoscopes contain two fiber optic sections inside a long tube.

Doctors used to have to operate to see what the problem was. One example is to use an endoscope to illuminate and visualise areas that couldnt normally be seen. 1 a i A ray of light passes through a length of curved optical fibre.

Optical fibre serves as a laser during performing a wide range of medical treatments that include surgeries biomedical research and microscopy. Advantages of Optical Fibre Communication Economical and cost-effective Thin and non-flammable. The Optical Fibre The medium for transmitting the light pulse signal.

Medical uses - Optical fibres are well suited for medical use. A BUNDLE OF PRECISELY ALIGNED FLEXIBLE OPTICAL FIBERS IS USED SOME FOR USE AS AN IMAGE GUIDE AND THE OTHER AS A LIGHT GUIDE ADDITIONALLY ANCILLARY CHANNELS MAY BE PRESENT FOR THE PASSAGE OF AIR WATER AS WELL AS REMOTE CONTROL IMPLEMENTS SUCH AS BIOPSY FORCEPS OR CYTOLOGY BRUSHES. 1 ii Describe one use of optical fibres in medicine.

In optical fibre system transmission losses are as low as 01 dbkm. It is mostly called endoscopy. You may draw a diagram.

Click hereto get an answer to your question ii Describe one use of optical fibres in medicine. Light travels down optic fibre s into or out of body. One of the most prevalent applications of fiber optics in medicine are in the imaging and illumination components of endoscopes.

Medical Industry Communication Defence Industries Broadcasting Lighting and Decorations Mechanical Inspections. Ii Describe one use of optical fibres in medicine. The word endoscope is derived from the greek words skopein and endom literally meaning to view within.

To examine internal organ part. Light travels both ways into and out of body OR. Draw a diagram showing the fibre and the path of the ray of light.

The application and uses of optical fibre can be seen in. You may draw a diagram. The use of fiber optics provides doctors the ability to deliver UV and IR laser power for the destruction and removal of diseased tissues the devices used are called arthroscopes or endoscopes.

ENDOSCOPY Buffer Core Cladding The. Draw a diagram showing the fibre and the path of the ray of light. Optical fibres can also carry enormous amounts of information as pulses of light.
