Low Dose (Low Dose Solution of CT [Reconstruction])

Reconstruction

Boost 3D

The number of photons reaching the detector can be severely reduced in highly attenuating anatomy. Due to excess noise and streak artifacts, these areas are traditionally imaged using increased mAs and/or kVp to overcome the low photon count. In response, Toshiba Medical has developed Boost3D, which employs an adaptive 3-dimensional algorithm to reduce pattern noise and streak artifacts. By minimizing noise and removing streak artifacts caused by photon starvation, Boost3D eliminates the need to increase the dose to obtain images of diagnostic quality.

QDS

QDS is an adaptive noise reduction algorithm that selectively smoothes out areas of uniform density while preserving the edge information within the image, thus reducing noise while increasing the signal to noise ratio and improving image quality.

AIDR 3D

Adaptive Iterative Dose Reduction in 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. 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 is able to eliminate up to 50% of image noise, resulting in a dose reduction of up to 75%.
