Designed for Precise Cardiac Imaging

Cardiac CT serves as a cornerstone in coronary and cardiac assessment, where precision directly determines patient treatment. Yet imaging the heart often involves complex challenges—soft and mixed plaques, stent and in-stent lumen evaluation, as well as blooming artifacts—all of which can degrade image quality and obscure critical details.
To overcome these hurdles, we developed CardioBoost, a cardiac-specific deep-learning reconstruction algorithm particularly trained to enhance clarity in these challenging scenarios and elevate diagnostic confidence.

3D Neural Network

Processing volumetric data, preserving spatial information.

Tissue Recognition & Classification

Boosting model robustness and improving tissue contrast.

Million-scaled Training Dataset

Optimizing resolution, enriching the depiction of subtle details.

Spatial Attention Module

Bringing clearer visualization of the targeting area such as plaques and stents.

Resolution Boost
Enhanced depiction of stent and stent lumen

Improvements in spatial resolution at the same radiation dose


*CardioBoost images compared with FBP based on phantom tests. Data on file.

Contrast Boost
Refined visualization of calcified or mixed plaques with clearer edges

At the same radiation dose, CardioBoost simultaneously achieves:

*CardioBoost images compared with FBP based on phantom tests. Data on file.

Artifact Suppression
With spatial attention module, CardioBoost can precisely target the highly-dense area, reducing blooming artifacts , and therefore providing a precise evaluation about the degrees of coronary stenosis.
