Kilovoltage
noun
controls the wavelength of the x-ray beam
Example: Don't forget to reduce the kilovoltage
fr: Kilovoltage
latent image
phrase
the invisible images left on the image receptor by the remnant radiations
Example: The latent image is appearing on the screen
fr: Image latente
miliamperage
noun
controls the rates at which x-ray are produced
Example: The milliampere are to low for this patient.

noun
the process by which unstable atoms undergo decay in an effort to obtain nuclear stability
Example: This rock is radioactive
fr: Radioactivité
Target filament
noun
A portion of the cathode in the xray tube; coiled wire made of tungsten, which produces electrons when heated

Ultrasound
noun
Use of high-frequency sound waves to produce an image of an organ or tissue
Example: A mass in Mary's appendix was detected and investigated using ultrasound and a CT scan.
