AutoRecon offers several automatic processing modules for single-photon emission computed tomography (SPECT) studies.
AutoRecon provides the following functionality:
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.
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.
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.
The filter page allows the user to view the effect of several filters on the raw data. This module can be used before reconstruction to select a more appropriate filter than the default one.
The upper and lower part of the page can be modified automatically to generate a bracket of parameters around the values of the central filter.

What is the CSI data browser? Our software packages are designed to be installed on your computer, not on vendor workstations. To use the quantitative applications studies need to be transferred from your acquisition systems to your computer with the Cedars-Sinai software. CSI allows you to transfer studies and manages the datasets on your computer. Its main features include:
