What are the components of the x-ray, ct scan, mri, ultrasound, new clear image, Position Emission Scanner? And how each one work?

Solution

Instrument

Components

How it works

X-Ray

Operating Console

High Frequency Generator

X-ray Tube

Internal and External Other Parts include

Collimator and Grid

Bucky

X-ray Film

Here the X-rays are irradiated on the body, some will be absorbed and some will pass through, these will produce the image.

ct scan

patient support

the positioning couch

the mechanical supports

the scanner housing.

the heart of the CAT Scanner

the x-ray tube

the detectors that generate and detect x-ray.

Here the X-Ray will be passed from a variety of directions through a slice of the object of patient and the CT scan will reconstruct the image from a large number of absorption profiles collected at the finite intervals from the object. Here the detector array will absorb the penetrated X-rays and will measure and transmit the information to the system.

MRI

Magnet

Gradient Coils

Radio Frequency (RF) coils

Patient Table

Antenna/Computer System.

The instruments takes the advantage that our body is made up of 63% water and MRI uses the hydrogen atoms, these will act like little magnets with north and south pole. By allowing the patient to lie inside a cylinder-shaped magnet, radio waves 10000 to 30000 times stronger than the magnetic field of the earth will be sent through the body, which affect the body\'s atoms and nuclei is forced into a different position and when they move back to their place, they will send the radio waves and these are picked by the scanner and turned into picture.

Ultrasound and new clear image

·        transducer probe

·        central processing unit (CPU)

·        Transducer Pulse Control

·        Display image

·        CD

·        Printer

Here sound waves are sent, when it strikes an object, it will bounce back or echoes. The echo waves will measure and the size, shape and consistency of the object will be determined and even the fluid present and volume.

Positron Emission Scanner

Scanner
Cyclotron
Tracer Lab equipment

First radiopharmacon will be administered and when isotope decays internally, radiopharmacon will be accumulated in the affected or diseased tissue, the electron interaction will produce annihilation, the emission of 2 gamma photons will be detected scintillating detectors and it will collected and stored to construct the 2D distribution map.
