cassette | tool that holds the xray film |
centimeters (cm) | measurement used in measuring body parts for xrays |
collimator | part of the machine that sets the size of the xray beam that produces radiation to take the picture |

dosimeter | xray badge that measures the amount of radiation a person is exposed to |
endoscope | fiber optic instrument used to visualize structures inside the body |
endoscopy | the procedure of visually examining the interior of the body by using an endoscope or a tool used to view the inside of the body |
film hanger | used to secure film for manual processing and development |
fixer solution | chemical the fixes the xray film and helps maintain the life span of the film allowing it to stay readable |
fixing | process of using a solution to maintain the life of an xray film |
grid technique | the plate that holds the film below the xray table |
hand tanks | large containers that hold chemicals and water from developing film |
intensifying screens | located within the film cassettee to help produce a better exposure to the film |

manual developing | developing xrays by hand using chemical tanks |
milliamperage (mA) | represents the number of xray beams based on time |
oblique | view used on areas that need to be placed at an angle to prevent double exposure from other body organs |
processing | process of developing film that involves being in a darkroom that has no light source or light leaks from outside areas |
radiation | safety hazard that allows xrays to be produced to take a radiograph |
radiology | the study of radiation |
radiolucent | appearing black or dark grey in color and may indicate soft tissue or air and may be an exposing factor relateding to increased exposure settings or improper patient measurement |
radiopaque | appearing white to light grey in color and may indicate hard tissue such as bone or may be an exposure factor in which the machine settings were too low or the patient was not properly positioned |

technique chart | a listing of settings on the xray machine based on the thickness of the area to be radiographed |
transducer | the instrument used with an ultrasound that scans the body and transmits the waves back to the screen |
ultrasound | diagnostic tool using ultrasonic waves to view images of internal organs and structures |
upper GI | a contrast sutdy of the structures of the upper digestive tract in which the barium is given orally |
ventrodorsal (VD) | animal positioned on its back with the xray beam going through the ventral area first (stomach) and the dorsal area second (back) |
xray | common term for radiograph |
xray log | records the patient's name, client's name, date, xray number, and xray position, thickness of body measurement, and area exposed |
xray tube | part of the machine that holds the radioation source |
