This is the official repository for the Slicer extension SlicerSPECTRecon. For details on how to use, see the user manual and the associated youtube video tutorial
This module enables the reconstruction of raw SPECT projection data, providing customizable options for image modeling and image reconstruction. The module has a SIMIND to DICOM converter to permit reconstruction of SIMIND Monte Carlo data.
The module is divided into the following sections:
- Data Converters: Provides tools for converting data from various sources into the DICOM format.
- Input Data: Users can select data from multiple bed positions after loading the projection data into the 3D Slicer DICOM database.
- System Modeling: Allows users to define transforms that are used to build the system matrix.
- Likelihood: Allows users to choose their preferred likelihood function.
- Reconstruction Algorithm: Provides the option of selecting a preferred reconstruction algorithm and their associated parameters
Please refer to the User_Manual.md file for further information
Within Slicer, the "SPECT reconstruction" module is located under the parent category "Tomographic Reconstruction". For more details, see the user manual
- Inputs
- SPECT projection data
- (optional) CT data for attenuation correction
- Outputs
- a 3D reconstruction SPECT image. The volume will be saved under the specified name (or as the dataset name appended with _reconstructed) and will be located within the Subject Hierarchy in the Data Module.
