Attenuation map estimation with SPECT emission data only
Quantitative SPECT can be well achieved if photon attenuation is taken into account in the reconstruction process. Using a transmission scan is a common approach. A dramatic simplification could be made if the attenuation map could be obtained from the emission data. In this paper, we propose a new method to estimate the attenuation map using the data consistency conditions of the attenuated Ra...
متن کاملAttenuation Correction Using SPECT Emission Data Only
A major step towards quantitative SPECT imaging may be achieved if attenuation, scatter and blurring effects are accounted for in the reconstruction process. Here we consider an approach which simultaneously estimates the unknown attenuation coefficient and the emission source using the emission data only. This leads to an inverse mathematical problem which could no longer be solved via iterati...
متن کاملJoint Estimation of Attenuation and Emission Images from PET Scans
In modern PET scanners, image reconstruction is performed sequentially in two steps regardless of the reconstruction method: 1. Attenuation correction factor computation (ACF) from transmission scans, 2. Emission image reconstruction using the computed ACFs. This reconstruction scheme does not use all the information in the transmission and emission scans. Post-injection transmission scans cont...
متن کاملAdvanced reconstruction of attenuation maps using SPECT emission data only
Today, attenuation corrected SPECT, typically performed using CT or Gadolinium line source based transmission scans, is more and more becoming standard in many medical applications. Moreover, the information about the material density distribution provided by these scans is key for other artifact compensation approaches in advanced SPECT reconstruction. Major drawbacks of these approaches are t...
متن کامل3D list-mode reconstruction for SPECT
| In previous work we developed a list-mode iterative reconstruction algorithm (LMIRA) for SPECT applied to two dimensional image reconstruction. In the 2D case we calculated the emission radiance distribution on the circular enclosure of the object. This part is the forward projection. In the backprojection we sampled the radiance on the intermediate layer using the geometric properties of the...
