Sentence examples for methods with attenuation from inspiring English sources

Images were reconstructed using iterative methods with attenuation correction.

The acquired three-dimensional emission data were reconstructed using a maximum a posterior (MAP) reconstruction method with attenuation correction.

Emission data were processed using iterative reconstruction (Fulham et al, 1997) (ordered-subset expectation maximisation method) with attenuation correction (Benard et al, 1999).

For image reconstruction, will be used a filtered backprojection algorithm, using Low-Pass filter Butterworth type (6.0 and a cutoff frequency of 0.3), and attenuation correction by Chang's method with an attenuation coefficient of 0.11 cm-1.

In the computational model this is achieved by adopting an implicit immersed-boundary method with the attenuation time scale smaller than the time step of an explicit fluid model.

In Monte Carlo-simulated images a good tumour volume and activity concentration accuracy is obtained for two segmentation methods (Otsu method and Fourier surface method) when images are reconstructed with attenuation and scatter compensation, while if including resolution compensation underestimated volumes and overestimated activity concentrations are obtained.

Ratiometric methods (with respect to optical attenuation and/or autofluorescence) partially correct this signal distortion [ 3, 4].

Attenuation correction was then performed in the reconstructed single photon emission computed tomography images with the non-uniform Chang's method and ordered subsets-expectation maximization attenuation correction methods with triple energy window scatter correction.

Images were reconstructed without and with attenuation correction (using Chang's method).

The CT images were reconstructed using the filtered back-projection method (512 slices), and acquired PET images were reconstructed by the 3D-MLEM method with CT-based attenuation collection.

Reconstructions were performed with attenuation and scatter corrections using the triple-energy window method.
