PILL CAMERA

Presented By LALKRISHNAN.S ROLL NO - 27

Guided By Sri.SAJITH KUMAR.S LECTURE IN E&C

INTRODUCTIONAim of technology is to manufacture products at molecular level.Achieved by nanotechnology.One such product is pill camera.A vitamin pill-sized , swallow able camera.Capture images of inside body.Study on captured images by the experts.Approved by FDA.

SPECIFICATION

Diameter 11mm.Length 26mm.Less than 4g.Bullet shape.

FEATURES

50,000 images are obtained during an 8 hour exam.Coating is non-adherent.Disposable.Charge-8 hour

COMPONENTS OF PILL CAMERA

5

1. OPTICAL DOME

2. LENS HOLDER

3. LENS

4. ILLUMINATING LEDs

5. CMOS IMAGE SENSOR

6. BATTERY

7. TRANSMITTER

8. ANTENNA

OPTICAL DOME

Frond part of the capsule.Light receiving window.Harmless.Easy orientation.Easy propelling

LENS HOLDER

Accommodates the lens.Lens is tightly fixed.Avoid dislocation of lens.

LENS

Integral component.Behind light receiving window.Light through window falls on the lens.

ILLUMINATING LED’S

Around lens & CMOS image sensor,4 LEDs are present.Arranged in donut shape.

CMOS IMAGE SENSOR

140º field of view.High sensitive Produce very high quality images.

BATTERY

Button shaped & 2 in number.Behind the CMOS image sensor.Silver oxide primary batteries.Disposable.Harmless.

TRANSMITTER

Behind the batteries.Two transmitting electrodes are connected to it.Electrodes are electrically isolated.

ANTENNA

It is arranged at the end of the capsule.It is enclosed in an dome shaped chamber.Receives data from transmitter.Send to data recorder.

PILL CAMERA PLATFORM COMPONENTS

DATA RECORDERSmall portable recording

device.Placed in the recorder pouch.

WORKSTATION AND RAPID SOFTWARE

Review and analysis.

ENDOSCOPY PROCEDURE

Capsule is swallowed by the patient like a conventional pill.It takes image as it is propelled forward by peristalsis.A wireless recorder, worn on a belt, receives the image transmitted by the pill.A computer workstation processes the data & produce a continuous still images.

DATARECORDER COMPUTER

IMAGES OBTAINED FROM PILL CAMERA

ADVANTAGES

Painless , no side effectMiniature sizeHigh quality image Avoid risk in sedation & radiationSimple procedureHarmless materialHIGH sensitivityEfficient than X-ray , CT scan , normal endoscopy

DISADUVANTAGESPatient with gastrointestinal structures or narrowing are good candidates for this procedure due to the risk of obstruction.Patients with pacemakers, pregnant women face difficulties.Impossible to control camera behavior.Very expensive.Not reusable.

APPLICATION

Tumors.Ulcer.Injury.Malabsorption.

FUTURE SCOPE

Capsule with a laser.Zooming and auto focus.Reduction in size.Cost effective.Longer battery life.

CONCLUSIONPill camera is a pioneering concept for medical technology of the 21 first century.The endoscopy system is the first of its kind to be able provide non-invasive image of the entire small intestine.It has revolutionized the field of diagnostic imaging to a great extent and has provide to be of great help to physicians all over the world.
