through the radiograph development process? - CORRECT ANSWER - Silver
What is the function of the screen of an X-ray cassette? - CORRECT ANSWER - To

The current accepted standard image format for digital radiographs is called DICOM (digital
imaging and communications in medicine). DICOM files have many advantages over other types
of image files. Which of the following is NOT true of DICOM images? - CORRECT
ANSWER - DICOM image files can be sent to other veterinarians or to owners and can be
viewed in almost any photo viewer
Which of the following choices most accurately describes the "heel effect" in diagnostic
radiology? - CORRECT ANSWER - X-ray beam intensity declines toward the anode side
of the x-ray machine
Many x-ray machines used in veterinary medicine have a 2-part exposure process. The first step
involves depressing a button or pushing a pedal half-way to prepare the machine for the exposure
and then a second button or fully depressing the pedal to take the exposure. What happens in the
x-ray machine when the first step is started? - CORRECT ANSWER - The anode rotates
and the filament is heated
Which of the following is NOT part of the axial skeleton? - CORRECT ANSWER - Limbs
Which of the following components or settings influence x-ray beam quality? - CORRECT
ANSWER - kVp and filtration

the portal of the X-ray tube
When taking a radiograph of the tibia and fibula, which of the following will occur if the x-ray
beam is perpendicular to the tibia and fibula but not to the x-ray cassette and film? - CORRECT
ANSWER - The tibia and fibula will appear elongate

involving what structure? - CORRECT ANSWER - Urinary bladder
Which of the following components of a digital radiography unit has the biggest influence on
image quality? - CORRECT ANSWER - Monitor
A double-contrast cystogram involves which of the following? - CORRECT ANSWER -
