Cathode ray tube

A partial vacuum tube that produced an electron stream and was used to study cathode rays and led to the discovery of x-rays.

Derived quantities

ionizing radiation

Radiation with sufficient energy to ionize atoms.

Mobile equipment

Imaging equipment that is designed to be easily transportable and can be taken to the patient’s bedside, to the emergency department, surgery, or wherever else.

Permanently installed equipment

Medical imaging equipment that is fixed in place in a specially designed and shielded room.

Radiologic quantities

The special radiologic science category of measure for dose, dose equivalent, exposure, and radioactivity.

Sievert

Dose received by radiation workers.

Time

Limit the amount of time exposed to ionizing radiation

Distance

Maintain a safe didstance from source of ionizing radiation

Shielding

Maximize the use of shielding from ionizing radiation exposure.

Beam restriction

Limiting the size of x-ray exposure field reduced the volume of tissue irradiated and limits the radiation dose to the patient.
