Terms | Definitions |
|---|---|
 ANODE | THE POSITIVELY CHARGED ELECTRODE OF THE X-RAY TUBE; SERVER TO DECELERATE THE ELECTRONS AS WELL AS STORE AND DISSIPATE HEAT |
| ATOM | THE SMALLEST DIVIDED PART OF MATTER THAT CAN ENTER INTO COMBINATION OR CHEMICAL REACTIONS WITH OTHER ATOMS |
| ATOMIC NUMBER | THE NUMBER OF PROTONS OR POSITIVE CHARGES IN THE NUCLEUS OF AN ATOM |
| ATOMIC WEIGHT | THE WEIGHT OF AN ATOM AS COMPARED TO THE WEIGHT OF A CARBON ATOM |
| CATHODE | THE NEGATIVELY CHARGED ELECTRODE IN THE X-RAY TUBE THAT SERVES AS THE SOURCE OF ELECTRONS |
| ELECTROMAGNETIC RADIATION | THE MOVEMENT OF ELECTRIC AND MAGNETIC FIELDS THROUGH SPACE AT THE SPEED OF LIGHT |
| ELECTRON | A NEGATIVELY CHARGED PARTICLE THAT REVOLVES AROUND THE NUCLEUS OF AN ATOM IN WELL-DEFINED ORBITS |
| ENERGY | THE CAPACITY FOR PERFORMING WORK |
| FOCUSING CUP | A METAL CUP THAT SURROUNDS AND HOUSES THE FILAMENT AND IS NEGATIVELY CHARGED; ITS PURPOSE IS TO CONDENSE OR FOCUS THE ELECTRONS PRODUCED BY THERMIONIC EMISSION |
| GLASS ENVELOPE | THE GLASS ENCLOSURE OF AN X-RAY TUBE THAT PROVIDES STRUCTURAL SUPPORT FOR THE COMPONENTS AND MAINTAINS THE VACUUM NECESSARY FOR OPERATION |
| HEAT UNIT | THE UNIT OF MEASURE OF THE HEAT PRODUCED IN AN X-RAY TUBE DURING THE PRODUCTION OF X-RAYS |
| HEEL EFFECT | THE UNEVEN DISTRIBUTION OF X-RAYS PRODUCED FROM THE ANODE TO CATHODE END OF THE TUBE; A DECREASE IN X-RAY INTENSITY AT THE ANODE END OF THE X-RAY TUBE |
| INERTIA | THE RESISTANCE A BODY OFFERS TO ANY CHANGE IN POSITION |
| IONIZATION | THE ADDITION OR SUBTRACTION OF AN ELECTRON FROM AN ATOM CAUSED BY BOMBARDING MATTER WITH X-RADIATION OR ELECTRONS |
| ISOTOPE | AN ATOM OF AN ELEMENT THAT HAS THE SAME ATOMIC NUMBER BUT MORE OR FEWER NEUTRONS |
| KILOVOLTAGE | A TECHNICAL FACTOR CONTROLLING THE QUALITY OF RADIATION PRODUCED BY A RADIOGRAPHIC OR FLUOROSCOPIC UNIT |
| KINECTIC ENERGY | ENERGY WHICH IS THE RESULT OF A BODY BEING IN MOTION |
| LINE VOLTAGE COMPENSATOR | A DEVICE THAT SENSES CHANGES IN INCOMING VOLTAGE AND ALLOWS FOR EITHER AUTOMATIC OR MANUAL ADJUSTMENT FOR THE CHANGES |
| MAGNET | A SUBSTANCE WITH THE POWER TO ATTRACT FERROMAGNETIC SUBSTANCES |
| MATTER | ANYTHING THAT AS MASS AND OCCUPIES SPACE; POSSESSES THE PROPERTY OF INERTIA |
| MILLIAMPERE(MA) | 1/1,000 OF A AMPERE |
| MILLIAMPERE-SECOND(MAS) | THE PRODUCT OF MILLIAMPERAGE AND TIME; A TECHNICAL UNIT TO DETERMINE THE QUANTITY OF RADIATION PRODUCED DURING A RADIOGRAPHIC EXPOSURE |
| MOLECULE | THE SMALLEST PART OF A SUBSTANCE THAT RETAINS ALL THE CHARACTERISTICS OF THE ORIGINAL SUBSTANCE |
| NEUTRON | A PARTICLE CONTAINED WITHIN THE NUCLEUS OF AN ATOM HAVING NO CHARGE |
| NUCLEUS | THE CENTRAL BODY OF AN ATOM, CONTAINING PROTONS AND NEUTRONS |
| POTENTIAL ENERGY | THE ENERGY INHERENT IN A BODY AT REST |
| PROTON | A PARTICLE CONTAINED WITHIN THE NUCLEUS OF AN ATOM, HAVING A POSITIVE ELECTRIC CHARGE |
| RAD | THE UNIT OF RADIATION ABSORBED DOSE RECEIVED BY HUMAN BEINGS OR ANIMALS |
| RECTIFICATION | A PROCESS THAT PREVENTS THE FLOW OF ELECTRONS FROM THE ANODE TO THE CATHODE |
| REM | THE RADIATION EQUIVALENT MAN; QUANTIFIES RADIATION DOSE FOR HUMANS |
| ROENTGEN(R) | THE UNIT OF RADIATION EXPOSURE OR INTENSITY; QUANTIFIES RADIATION OUTPUT OR EXPOSURE |
| TRANSFORMER | TWO COILS OF WIRE, INSULATED FROM ONE ANOTHER AND WRAPPED AROUND A SINGLE IRON CORE WHOSE PURPOSE IS TO CHANGE VOLTAGE FROM ONE LEVEL TO ANOTHER |
| WORK | THE FORCE APPLIED MULTIPLIED BY THE DISTANCE THROUGH WHICH THE FORCE ACTS |
