Objective: Energy-weighted acquisition (EWA) is a commercially available technique
designed to reduce the contribution of Compton scattered radiation in the final image. This …

Energyweightedacquisition (EWA) is a techniquefor improvingimagecontrastby correcting for
some of the blurring effects of Compton scattering within the patient. We outline image …

In this study we investigate the feasibility of acquiring dual energy transmission projection
data using a conventional gamma camera. Transmission projection data are acquired …

Bone single-photon emission computed tomography (SPECT)/computed tomography (CT)
imaging suffers from poor spatial resolution, but the image quality can be improved during …

Objective: One of the major problems than can affect image quality of bone scan is poor
target to non target ratio, due to scattered photons. The ideal Tc-99m energy spectrum is line …

Historically in nuclear medicine the acceptance window for total-energy pulse-height has
been set to maximize contrast and resolution in the image. Recently, there has been …

Compton scattering is thought one of the factors which led to inferior quantification of
SPECT. To improve SPECT quantification, energy-weighted acquisition (EWA) was studied …

Recently emission imaging exploiting Compton scattered radiation has been shown to be a
feasible three-dimensional imaging modality, in particular for medical imaging. It exhibits …

A major problem in nuclear medicine is the image degradation due to Compton scatter in the
patient. Photons emitted by the radioactive tracer scatter in collision with electrons of the …

[en] An energy-weighted acquisition (EWA) technique has been implemented that utilizes all
scintillation events, weighting their contribution depending on energy to formulate a …
