An image that demonstrates low contrast can be caused from: 1. High mAs 2. Low kVp 3. Insufficient beam restriction correct answer: 3 only Which of the following interactions with matter reduce contrast in an x-ray image? correct answer: compton scattering What type of fracture is illustrated below? (femur bone sticking out of skin) correct answer: compound fx From anatomical position, pronating the hand will result in the palm facing ____ correct answer: posteriorly With all oth...

X-rays: Typical diagnostic wavelength and photon energy range. - Answer-100ev-200 keV min. wavelength 6pm-12nm Structure and function of the x-ray tube. - Answer-A vacuum tube with an anode and a cathode. The cathode is heated and electrons are emitted, they are accelerated by a voltage difference in the tube. When the "brake" against the material of the anode, they release their high kinetic energy in the form of an x-ray. *x-ray tubes are of very low efficiency, most of the radiation i...

CT Boot Camp Section 1, CT Boot Camp Questions and Answers 100% Pass A single "view" acquired during a CT scan is also called a: -Projection A CT scanner collects several projections as the tube and detectors spin around the patient. Each of these projections represent a unique view of the anatomy that is eventually compiled together to form the 3D volume of data The main difference between image production in CT compared to image production in radiography is: -Projections are compiled into ...
