Class to store parametric images.
| DiscDensT | should be a class for storing an image, e.g. VoxelsOnCartesianGrid<KineticParameters<..> > |
This class stores parametric images as an image of parameters (as opposed to a sequence of images, one for each parameter). However, it provides various functions to get single images out, e.g. corresponding to a single parameter, or by applying a function on all parameters.
Note that the ExamInfo object stored by the image can contain multiple time frames (presumably corresponding to the time frames of the data where the parametric image is derived from). In some cases, there could only be a single time frame (start to end of the study).
| typedef ParametricDiscretisedDensity stir::ParametricDiscretisedDensity< DiscDensT >::hierarchy_base_type |
A typedef that can be used what the base of the hierarchy is.
For these purposes, we don't use DiscDensT (even though it's the base_type).
This typedef is used in write_to_file().
| stir::ParametricDiscretisedDensity< DiscDensT >::ParametricDiscretisedDensity | ( | const DynamicDiscretisedDensity & | dyn_im | ) |
Create blank parametric image from a dynamic image.
Uses only its geometric/exam info and timing
| stir::ParametricDiscretisedDensity< DiscDensT >::ParametricDiscretisedDensity | ( | const SingleDiscretisedDensityType & | im | ) |
Create blank parametric image from a single VoxelsOnCartesianGrid.
Uses only its geometric/exam info and timing
