Question | Answer |
---|---|
BLURRED IMAGES | RESULTS OF MOVEMENT OF PATIENT'S HEAD OR TUBEHEAD FROM X-RAY MOVING IN MOUTH. |
ELONGATION | VERTICAL ANGULATION ERROR CAUSED BY TOO LITTLE ANGULATION |
VERTICAL ANGULATION | ADJUSTMENT OF ANGULATION FROM TOP TO BOTTOM |
DEVELOPER | HAS A PH ABOVE 7 & CHEMICALLY REDUCES THE EXPOSED AREA OF EMULSION |
HORIZONTAL ANGULATION | ADJUSTMENT OF ANGULATION FROM LEFT TO RIGHT |
MILLIAMPERAGE | MEARSUREMENT UNIT FOR ELECTRICAL CURRENT (AMOUNT OF ELECTRONS) |
SECONDARY RADIATION | FORMS WHEN PRIMARY X-RAY STRIKES THE PATIENT OR CONTACT MATTER |
PRIMARY RADIATION | CENTRAL BEAM THAT COMES FROM THE X-RAY TUBEHEAD |
FORESHORTENING | VERTICAL ANGULATION IS LARGER THAN NECESSARY. (TOOTH LOOKS SHORTER/WIDER) |
CEPHALOMETRIC RADIOGRAPH | USED TO ASSESS THE PATIENT'S SKELETAL STRUCTURE |
OVERLAPPING | CAUSED BY INCORRECT HORIZONTAL ANGULATION (UNO ENCIMA DEL OTRO) |
DOSIMETER BADGE | MONITORS AN INDIVIDUALS RADIATION EXPOSURE |
COLLIMATOR | LEAD DIAPHRAGM |
KILOVOLTAGE | DETERMINES THE QUALITY OR PENETRATION POWER OF THE CENTRAL BEAM |
CONE CUTTING | X-RAY BEAM MISSED PART OF THE FILM; ONLY PARTIAL EXPOSED |
RADIOPAQUE | NOT TRANSMITTING LIGHT |
BITEWINGS RADIOGRAPH | PIC OF THE CROWNS, INTERPROXIMAL SPACES & AREA OF ALVEOLAR BONE |
ALARA | CONCEPT FOR RADIATION PROTECTION. AS LOW AS REASONABLY ACHIEVABLE |
RADIOLUCENT | BLACK REGION ON THE X-RAY INDICATING WHERE RADIATION PASSED THROUGHT THE TISSUE |
HERRINGBONE PATTER | TIRE TRACK PATTER ON X-RAY |
CATHOLE | NEGATIVE TERMINAL OF X-RAY TUBE |
SCATTERED RADIATION | DEFLECTED FORM ITS PATH AS IT STRIKES MATTER |
CONTRAST | DIFFERENCE BETWEEN SHADES OF GRAY |
FIXER | REMOVES UNEXPOSED & UNDEVELOPED CRYSTALS FROM FILM-EMULSION AS WELL AS STOPPING PROCESS |
DENSITY | DEGREE OF DARKNESS ON X-RAY |
LEAKAGE RADIATION | ESCAPES IN ALL DIRECTIONS FROM TUBE OR TUBEHEAD |
OCCLUSAL RADIOGRAPH | PICS OF LARGE AREAS OF THE MANDIBULAR & MAXILLARY |
ANODE | POSITIVE TERMINAL OF AN ELECTROLYTIC CELL |
PERIAPICAL RADIOGRAPH | PICS OF ENTIRE TOOTH & SURROUNDING AREA |
PANORAMIC RADIOGRAPH | SHOWS ENTIRE MAXILLARY & MANDIBULAR ON ONE FILM |
