________________ is the pattern on the image that is generated by patient anatomy that is always present but not important for the diagnosis.
Electronic Noise
Structured Noise
Anatomical Noise
Grain Noise
Quantum Noise
This is a noise that happens when the flow of electrons (current) conveys the signal at one or more points in the imaging chain. There are electrons that resulted from actual signal detection events (in CT, MRI, nuclear imaging, etc.), and there are also electrons that are added to the signal that are not the result of signal detection events.
Electronic Noise
Structured Noise
Anatomical Noise
Grain Noise
Quantum Noise
Most pixelated detectors have a number of parallel channels for reading out the array of detector elements, and this reduces readout time. Each channel uses its own amplifier circuits and these circuits cannot be perfectly tuned with respect to each other.
As a result, groups of detector elements that are read out may have different _______________________
Electronic Noise
Structured Noise
Anatomical Noise
Grain Noise
Quantum Noise
When the number of quanta used to illuminate a scene is large, there is virtually no noise in the visual image. In low-light imaging environments, such as when night vision glasses are used, significant levels of optical quantum noise are seen. In the radiology department, to reduce radiation dose to the patient from x-rays or gamma rays, imaging modalities based upon ionizing radiation use relatively few quanta to form the image—indeed, the numbers of quanta are so low that for most medical images involving x-rays or gamma rays, appreciable noise in the image results, and this noise is called ________________________
