SyngoExplorer


The SyngoExplorer (SX) is a collection of software tools dedicated to retrospective CT image reconstruction, image post processing and related tasks. Its user-friendly interface allows clinicians to perform off-line PC-based image reconstruction. In contrast to the scanner’s reconstruction that is hardware-based the IR taskcard of the SX uses a purely software-based reconstruction. It can run on almost any computer that runs syngo®.

It uses the syngo® (Siemens Healthcare, Erlangen, Germany) environment to manage patient data and to allow full local and remote database access. Each SX tool is realized as a taskcard that is added to your syngo® frontend. The collection of SX tools currently consists of the image reconstruction (IR) taskcard and the topogram reconstruction (Topo) taskcard. Depending on your configuration, one or more of these may show up together with other standard syngo® applications, e.g. the viewing taskcard, the 3D viewing taskcard, the filming taskcard and others.

The IR taskcard provides standard as well as additional image reconstruction functionality for the Somatom Sensation 16 and Sensation 64 and Sensation Open (Siemens Healthcare, Forchheim, Germany) CT scanners. Standard features are the reconstruction of sequence and spiral rawdata. The respective algorithms are implemented equivalent to the scanner’s reconstruction; images reconstructed with identical parameters will look the same.

The IR taskcard also permits advanced tasks such as phase-selective cardiac imaging (ECG and kymogram) without interfering with the clinical routine. In addition, a number of dedicated algorithms for improving CT images are brought to a level where they can be used very well outside of a solely scientific environment. MAF, our patented noise reducing but resolution preserving algorithm, within regions of high attenuation in CT offers a high potential for improved image quality and for further dose reduction. Metal artifacts in orthopedic and dental images can be reduced decisively with the use of the integrated metal artifact reduction (MAR).

In addition to the reconstruction- and image-related features the SyngoExplorer offers an application that focuses on the issue of dose in CT. The DoseTutor , a feature of the IR taskcard, adds virtual noise to measured patient rawdata in order to simulate a corresponding scan with a lower mAs value helping to estimate the dose reduction potential for clinical protocols in CT.

The purpose of the Topo taskcard is to reconstruct and filter topogram rawdata files. The new Siemens Somatom Sensation 64 cone-beam spiral CT scanner provides functionality to store the last scanned topogram. With the Topo taskcard it is now possible to retrospectively reconstruct topogram rawdata on any syngo® machine. There are additional reconstruction kernels available and and larger matrices can be chosen (e.g. 2048 x 2048) than on the scanner.

The implementation of the SyngoExplorer is based on the syngo® platform. It therefore offers full connectivity within a DICOM-oriented environment and provides dedicated graphical tools for further image post-processing and display. In addition to the DICOM connectivity import and export of series of binary image data is available.
