Radiography In Vet Tech Objectives

Front 1

DESCRIBE HOW X-RAYS ARE PRODUCED

Back 1

X-RAYS ARE ENERGY PARTICLES PRODUCED BY THE X-RAY TUBE. X-RAYS ARE GENERATED WHEN FAST-MOVING ELECTRONS (SMALL PARTICLES BEARING A NEGATIVE CHARGE) COLLIDE WITH ANY MATTER.

Front 2

DISCUSS THE PROPERTIES OF X-RAYS

Back 2

INTERACT WITH AN ATOM; GIVE OFF ONLY PART OF ITS ENERGY; MOVE IN A NEW DIRECTION (PARTIAL ABSORPTION); GIVE OFF ITS ENERGY COMPLETELY TO THE ATOM IT INTERACTS WITH (COMPLETE ABSORPTION); PENETRATE THROUGH THE MATTER WITHOUT INTERATING AND PRESERVE ITS ENERGY

Front 3

IDENTIFY THE PARTS OF AN X-RAY MACHINE

Front 4

DESCRIBE THE DANGERS OF X-RAYS

Back 4

ALL LIVING CELLS ARE SUSCEPTIBLE TO IONIZING RADIATION DAMAGE;

Front 5

RECOGNIZE ACCEPTABLE SAFETY PROCEDURES

Back 5

DON'T PLACE ANY PART OF THE UMAN BODY IN THE PRIMRY X-RAY BEAM AT ANY TIME;
NO PREGNANT WOMAN;
NO ONE UNDER 18;
IT CAN BE DEADLY IF NOT HANDLED PROPERLY

Front 6

DESCRIBE HOW A RADIOGRAHIC IMAGE IS PRODUCED

Back 6

X-RAYS PASS THROUGH AN ANIMALS BODY PART AND THEN HIT THE X-RAY FILM;
WHEN THE X-RAYS HIT THE FILM, THE FILM TURNS BLACK IN THAT AREA;
THE MORE X-RAYS THAT HIT AN AREA, THE DARKER THE AREA TURNS AFTER PROCESSING

Front 7

DISCUSS FACTORS THAT INFLUENCE THE RADIOGRAPHIC IMAGE

Back 7

1- TOTAL # OF X-RAYS THAT REACH THE FILM
2- PENETRATING POWER OF THE X-RAYS
3- DEVELOPING TIME
4- TEMPERATURE OF THE DEVELOPER
5- THICKNESS AND TYPE OF TISSUE BEING RADIOGRAPHED

Front 8

IDENTIFY AND CORRECT IMAGE FAULTS

Back 8

1- ARTIFACTS- RADIOGRAPH IS BLUR CAUSED BY PATIENT MOVEMENT. CORRECT IT BY USING POSITIONING BOXES, SANDBAGS, AND SPONGES
2- HAVE THE BODY PART BEING RADIOGRAPHED AS CLOSE TO THE FILM AS POSSIBLE AND PARALLEL TO THE FILM

Front 9

PROPERLY POSITION FOR ROUTINE SMALL-ANIMAL RADIOGRAPHS

Back 9

COMFORT AND WELFARE OF THE PATIENT SHOULD BE CONSIDERED AT ALL TIMES;
A CALIPER IS USED TO MEASURE THE ANATOMIC AREA OF INTEREST;
2 VIEWS ARE TAKEN OF EACH ANATOMIC AREA TAKEN AT RIGHT ANGLES TO EACH OTHER ARE THE MINIMUM RECOMMENDED;
COLLIMATION;
CENTRAL X-RAY BEAM SHOULD BE CENTERED DIRECTLY OVER THE AREA OF INTEREST;
PATIENT SHOULD BE CLEAN AND FREE OF ANY DEBRIS;
CHEMICAL RESTRAINT IS PREFERRED; AND
SEDATION IF NECESSARY

Front 10

DISCUSS THE PROCEDURE FOR DEVELOPING RADIOGRAPHS

Back 10

1- PREPARATION; CHEMICALS SHOULD BE AT 68 DEGREES F AND SHOULD BE STIRRED.
2- UNLOADING THE CASSETTE; OPEN THE BACKPLATE OF THE CASSETTE AND GENTLY SHAKE THE TOP SO THAT TE FILM CAN BE GRASPED BY THE CORNER BETWEEN THE THUMB AND FOREFINGER
3- LOADING THE FILM ON A HANGER; TENSION CLIP HANGER S LOADED BY INSERTING THE FILM INTO THE BOTTOM, STATIONARY CLIPS FIRST, THEN ROTATING THE HANGER RIGHT SIDE UP AND INSERTING THE FILM INTO THE MOVEABLE SPRING
4- DEVELOPING THE FILM; FILM IS IMMERSED IN THE DEVELOPING TAK, AN THE HANER IS AGITATED 2-3 TIMES TO REMOVE ANY AIR BUBBLES FROM THE FILM SURFACE, THE LID ON THE DEVELOPER TANK IS REPLACED, AND THE TIMER IS SET FOR THE APPROPRIATE DEVELOPMENT TIME
5- RINSING THE FILM; WHEN THE TIMER SOUNDS, THE FILM SHOULD BE REMOVED FROM THE DEVELOPER RADIDLY TO AVOID EXCESSIVE DRIPPING BACK INTO THE DEVELOPER TANK, THE HANGER SHOULD BE TILTED, THE FILM IS IMMERSED I THE RINSE BATH AND AGITATED FOR 30 SECONDS
6- FIXING THE FILM; AFTER THE FILM HAS BEEN IN THE RINSE TANK FOR 30 SECONDS, IT SHOULD BE DRAINED OF EXCESS WATER AN IMMERSED N THE FIX TANK, THE FILM IS AGITATE 2-3 TIMES TO REMOVE ANY AIR BUBBLES ON THE FILM SURFACE, AND THE TIMER IS SET FOR THE APPROPIATE DURATION. DURATION OF THE FIXATION PROCESS IS USUALLY TWICE THE CLEARING TIME AND UNTIL AFTER THE FILM HAS LOST ITS "MILKY" APPEARANCE
7- WASHING THE FILM; FILM IS REMOVED FROM THE FIX QUICKLY SO THAT CHEMICAL CARRYOVER ENTERS THE WASH TANK, FILM SHOULD WASH FOR 20-30 MINUTES FLOW SHOULD HAVE APPROXIMATELY 8 COMPLETE CHANGES PER HOUR
8- OPTIONAL FINAL RINSE; A WETTING AGENT CAN SPEED THE DRYING TIE AND PREVENT WATER MARKS ON THE FILM SURFACE, THE FILM IS BRIEFLY DIPPED IN THE WETTING AGNT BEFORE DRYING
9- DRYING THE FILM; FILM SHOULD BE DRIED IN A DUST-FREE AREA TO PREVENT ARTIFACTS FROM STICKING TO THE WET FILM SURFACE

Front 11

DISCUSS THE PROCEDURE FOR PERFORMING COMMON CONTRAST STUDIES

Back 11

A CONTRAST MEDIUM BE ADMINISTERED TO AN ANIMAL TO INCREASE RADIOGRAPHIC CONTRAST WITHIN AN ORGAN OR SYSTEM. SOFT TISSUE STRUCTURES CAN BE VISUALIZED, AND THE STRUCTURE UNDER INVESTIGATION CAN BE EVALUATED FOR SIZE, SHAPE, AND POSITION. DEFECTS IN THE MUCOSAL SURFACE OF AN ORGAN OR ITS LUMINAL CONTENTS CAN BE IDENTIFIED

Front 12

EXPLAIN THE PRINCIPLES OF LARGE-ANIMAL AND EXOTIC RADIOGRAPHS

Back 12

2 MAJOR DIFFERENCES ARE SIZE AND POSTURE;
ANIMAL IS PLACED IN A STANDING POSITION;

COMPUTED TOMOGRAPHY;
NUCLEAR SCINTIGRAPHY;
