What is Phantom? |
The International Commission on Radiation Units and Measurements (ICRU) defines a "tissue substitute" as any material that simulates a body of tissue in its interaction with ionizing radiation and a "phantom" as any structure that contains one or more tissue substitutes and is used to simulate radiation interactions in the human body.
Phantoms date back to the beginning of the 20th century. In the 1920's, -water tanks and wax blocks were often used for x-ray experiments and to this day these materials are still in use in certain applications. In the 1960's more reliable tissue substitutes and sophisticated phantoms began to appear.
Today, phantoms are used to perform numerous tasks within the field of medical imaging and radiation therapy. This includes testing the performance of imaging equipment, measuring radiation dosage during therapy, teaching interventional image guided procedures, and servicing- equipment in the field.
