Multiple Choice

Spatial resolution is defined as

• A)the ratio of the number of detected events to the number of source emissions.
• B)geometric efficiency and is defined as the fraction of emitted photons (gamma or x-rays) that hit the detector; it depends on the detector configuration and its distance from the source.
• C)the fraction of gamma rays that are detected when they hit the detector; it depends on the thickness (t) and attenuation coefficient (\(\mu\)) of the detecting material.
• D)the amount of blurring that is produced by an imaging system characterized by point spread function and line spread function.
