In the parallelproj wrapper in STIR there still seem to be a couple of issues. Currently, there are artifacts on either side of the sinogram when forward-projecting a sphere (or...
The ray-tracing projector creates small artefacts when configured to use more than 1 tangential LORs. To reproduce the issue, run the test BlocksTests::run_symmetry_test() in recon_test/test_blocks_on_cylindrical_projectors.cxx and look at the sino1_from_image.hs,...
If you run cmake-gui (or ccmake) first, and then change CMAKE_INSTALL_PREFIX, then it keeps PYTHON_DEST (and STIR_CONFIG or so) pointing to the original, i.e. /usr/local on Linux.
This is a ticket to merge several small changes into UCL/master, if they are deemed acceptable ;-)
Added a call to get the max_FOV_radius of the scanner, to fix the parallelproj interface for non-cylindrical scanners.
## Changes in this pull request Added the functionality to downsample BlocksOnCylindrical scanners in views and detectors per ring during scatter simulation, in order to speed up the computations. The...
As part of the scatter speedup work with downsampled scanners (https://github.com/UCL/STIR/pull/1291), I noticed that there was always a large artifact at the bottom of the scatter estimate (~15% error), irrespective...
For the NeuroLF scanner geometry, four iterations of scatter estimation take around 9 minutes of which the majority is spent doing the single scatter simulation. This is because the detectors...
Currently, most calls of warning() use the deprecated version of the function. This function turns out to ignore the verbosity. I would propose to replace all these calls to the...
