Automated SPECT Reconstruction

AutoRecon, also known as AutoSPECT™ on Philips platforms, offers several automatic processing modules for single-photon emission computed tomography (SPECT) studies.

Automated SPECT Reconstruction

AutoRecon offers several automatic processing modules for single-photon emission computed tomography (SPECT) studies. AutoRecon provides the following functionality:

  • Reconstruction

    The purpose of this first module is to reconstruct the data from projections using a variety of algorithms (including iterative reconstruction). The reconstruction page shows the filter and its parameters, as well as the data. From top to bottom: raw projection data, filtered projection data and transverse reconstructed slices.

  • Reorientation

    Once the data has been reconstructed, this module processes transaxial images to reorient them automatically into short-axis (oblique) myocardial perfusion SPECT images.

    First, this module determines the extent of the left ventricle, thus limiting subsequent operations to a restricted amount of data. This is done by segmenting the left ventricle by iterative clustering and rule-based location/size/shape criteria.

    The final mid-myocardial surface is then determined by an iterative process that incorporates additional constraints of shape and texture and uses information from the nonsegmented transaxial image.

  • Motion Correction

    The motion page presents information in a different manner. Raw projections (corrected and uncorrected) are shown in the top row. The bottom part shows the sinogram and the correction control window.

    Each row in the sinogram corresponds to a projection in the original raw data. The pixel values in the sinogram for a particular row are the values of the voxels located along the intersection of the chosen transverse plane and raw projection plane.
