13, 18, 22— 24). It was therefore hypothesized that, if the photopeak region was divided
into two nonoverlap** energy windows, a regression relation could be obtained between …

A method for scatter correction using dual energy window acquisition has been developed
and implemented on data collected with a brain-PET tomograph operated in the septa …

A practical triple energy window technique (TEW) is proposed, which is based on using the
information in two lower energy windows and one single calibration, to estimate the scatter …

In scintigraphy, the detection of scattered photons degrades both visual image analysis and
quantitative accuracy. Many methods have been proposed and are still under investigation …

Although quantitative single-photon emission computed tomography (SPECT) has been the
goal of much research effort for a number of years, only recently has it received wide …
