High-Speed Volume Reconstruction System
A new volume reconstruction method is employed in which the entire scan volume is reconstructed at one time. In conventional systems, axial images are reconstructed individually.
A single volume can be reconstructed in a maximum of 10 s using a dedicated image reconstruction system in which multiple Field Programmable Gate Arrays (FPGAs) are installed.
Processing speed is increased substantially by eliminating time-consuming repeat processing of individual slices.
Data items are compartmentalized for parallel processing so that processing of new items is performed in succession as each part of the current processing is completed. This reduces total processing time.
AIDR 3D (Adaptive Iterative Dose Reduction 3D)
AIDR 3D is the latest evolution of iterative reconstruction technology that has been fully integrated into the imaging chain to ensure automatic dose reduction for all your CT examinations.
With the inclusion of AIDR 3D in the scan protocol, the calculated exposure is automatically reduced by up to 75% as compared to a scan performed with traditional filtered backprojection reconstruction.
Once the scan has been performed with low-dose parameters, automatic reconstruction with AIDR 3D is performed. This advanced iterative reconstruction algorithm works in two parts. The first part adaptively removes photon noise in the 3D raw data domain. This is followed by the second part, model-based iterative noise reduction in the reconstruction process.
AIDR 3D reconstruction has therefore been systematically optimized to minimize the impact on patient throughput. As a result, advanced iterative reconstruction with AIDR 3D adds mere seconds to the total reconstruction time.
Myocardial Perfusion
The results of the CorE64 multicenter trial have shown that coronary CTA has the potential to become a diagnostic tool equivalent to conventional coronary angiography. Following this trial, Myocardial Perfusion has been developed as an advanced application for quantitative perfusion analysis.
- Whole-heart acquisition in a single temporally uniform volume
- Accurate diagnosis: Myocardial Perfusion combined with coronary CTA can accurately assess myocardial perfusion and identify the coronary arteries responsible for ischemia.
- Ultra-low dose: All required perfusion data can be obtained by just one scan.
Body Perfusion
Toshiba's Body Perfusion software is an advanced application for the quantitative analysis.
- Whole-organ temporal uniformity
- Fully automated non-rigid volume position-matching software
- Low-dose perfusion scan protocol
- Interactive control of functional color overlay on morphological images
