SPECT/CT Imaging of Radiation Dose Estimates

Caption

(A) Initial coarse alignment of full image volume for serial 4-, 24-, and 96-h quantitative SPECT images. (B) Output of focused image registration based on contour-defined mask (dashed region of serial maximum-intensity projections in A). Three-color maximum-intensity projection is used to verify alignment for serial quantitative SPECT images, with 3-dimensional contour region highlighted. Black indicates good alignment whereas color-fringing shows areas with spatial offset. (C) Three-phase exponential curve is generated and parameters are used for subsequent population analysis.
