CST Specifications and Features
| RECONSTRUCTION | |
|---|---|
| Algorithms | Statistical (Iterative)Reconstruction (SR) and Feldkamp Backprojection (FDK) |
| GPU Support | Nvidia, multiple GPUs, offload to RAM if VRAM exceeded |
| Tunability | Extensive possibilities on both SR and FDK |
| Air norm | Flat Value, Adaptive, Image based |
FDK (left) and SR (right) Reconstruction. SR is slower but preserves surface.
| 2D IMAGE PROCESSING | |
|---|---|
| Lag Correction (See Video below) | Dramatically reduce lag content in CT Projections. |
| Beam Hardening | Many material presets, ability to add custom materials |
| 2D Detector Scatter | Varex Detector Scatter Models |
| 2D Object Scatter | Material and Spectrum Dependent Corrections |
| 2D AI Scatter | Machine Learning Corrections available for highly repetitive data (For example Inline CT) |
| Resolution Enhancement | Remove Scintillator Blur with Varex Detector Pixel and Scintillator models. |

| SYSTEM GEOMETRY CALIBRATION (GeoKit) | |
|---|---|
| Precision Phantoms | Different Sizes of Varex Phantoms available for Standard and Micro-Focus Systems |
| Absolute Values | Geokit determines SID, SAD, Focal Length, Piercing Point, etc for full determination of your system’s geometry. |
| 9 Degrees of Freedom | Position and Orientation of Source, Detector and Rotation Axis. |
| Dynamic Geometry, as well as Static | Full (Absolute value) 9-DOF data available per-frame, for systems with geometries that vary throughout the trajectory. |

| VOLUME-BASED (3D) PROCESSING | |
|---|---|
| Material Segmentation | Separate out materials in your scan volume |
| Metal Artefact Correction (MAR) | Detect Metal and reduce or eliminate negative image quality effects |
| 3D Scatter Correction ” 3D Vsharp” | Hardware free, highly effective, highly adaptive scatter elimination. |
| 3D Multi Material Beam Hardening | Reduce or eliminate beam hardening effects in multi material volumes. |
MAR ON (top right): Measurements enabled on clean surface, in spite of metal spring.
MAR OFF: (top left): Measurements impossible: artefacts from metal spring prevent surface determinations.
