Abstract
En 中文
Emission computed tomography (ECT) studies were performed on test objects and dogs. Conjugate views were obtained for 60-120 projections equispaced around 360.degree. by rotation of the subjects in front of a .gamma.-camera. A convolution reconstruction algorithim in which .gamma.-ray attenuation corrections are included in the backprojection step were used to reconstruct the emission images. Reconstructions of X-ray transmission data provided data for .gamma.-ray attenuation corrections of the emission images of 99mTc-pyrophosphate uptake in dogs. Reconstructed images of test objects show spatial resolution uniformity and attenuation corrections enable estimation of relative activity densities to within 10-15% rms errors, thus demonstrating quantitative imaging capabilities of ECT.
