In each blank, try to type in the
word that is missing. If you've
typed in the correct word, the
blank will turn green.
If your not sure what answer should be entered, press the space bar and the next missing letter will be displayed. When you are all done, you should look back over all your answers and review the ones in red. These ones in red are the ones which you needed help on. Question: The component of a CR image plate that records the image is Answer: photostimulable Question: the luminescent light emitted by the PSP is into the image seen on the CRT by the Answer: ADC (analog to converter) Question: SId affects recorded detail in of the following ways?Answer: directly Question: Grid material is made up of what?Answer: Aluminum and plastic Question: In a duration of 0.05 second was selected for an what mA would be necessary to produce 30 mAs?Answer: 600 Question: Unopened boxes of radiographic film should be away from radiation and Answer: in the position Question: The term windowing describes the ofAnswer: changing the image brightness and/or scale Question: can be caused by Answer: the radiographic object being at an angle to the IR Question: what does not affect the exposure rate of the beam?Answer: size Question: a patient with heart failure has to have what done to the technique for a PA chest Xray?Answer: Question: Misalignment of the tube-part-IR results inAnswer: distortion Question: the direction of electron travel in the xray tube Answer: to anode Question: for the same FOV the spatial resolution will be using Answer: a matrix Question: which of the following technical change would best serve to the effect of very dissimilar tissue densitiesAnswer: high KV factors Question: the absorption of radiation by a grid is called Answer: grid Question: during CR , the latent image present on the PSP is changed to a computerized image by the Answer: ADC Question: How are mAs and patient dose ?Answer: directly Question: the reduction in xray photon intensity as the passes through material is termedAnswer: attenuation Question: xrays are generally associated with Answer: high and short wavelength Question: At what of the xray beam is the effective focal spot the largest?Answer: at the end Question: the intensity of radiation decreases as Answer: distance from the source of increases Question: what is the purpose of the thin of lead that is often location in the rear portion of the IPAnswer: to scatter radiation Question: the purpose of the electroconductive layer of the CR PSP is to Answer: facilitate transportation through the /reader Question: the xray image seen on the display monitor is aAnswer: image Question: the accessory used to measure the thickness of body parts in order to determine selection of exposure factors is theAnswer: Question: a radiograph made with a grid demonstrates decreased density on its lateral edges. this is most likely due toAnswer: decreased Question: a particular mAs value, regardless of the combination of the mA and time, will reproduce the same radiographic , this is a statement of the Answer: reciprocity Question: the relationship between the height of a grid's lead strips and the distance them is referred to as gridAnswer: Question: because of the heel effect the intensity of the xray beam is greatest along theAnswer: cathode end of the Question: in digital imaging, TFT DEL size is toAnswer: spatial |
