 Cardiac - 3D CT Software
Advanced Signal Processing Technologies for Cardiac CT and 3D Medical Imaging
Converts a single slice CT scanner into a state of the art CT with the equivalent Cardiac and 3D imaging capabilities of a multi-slice CT scanner.
Offers a low cost software solution for cardiac CT diagnostic imaging (removal of cardiac motion artifacts, detection of coronary calcification, calcium scoring)
Provides a user friendly 3D imaging functionality
Compatible with a wide variety of systems; new or old single or multi-slice CT scanners
Does not require changes or steps of operations in the original CT equipment settings
Easy to setup, easy to operate
Overview
CANAMET’s Cardiac – 3D CT software, upgrades the functions of a single-slice CT
scanner into a state-of-the-art CT with the equivalent cardiac and 3D imaging
capabilities (removal of cardiac motion artifacts, detection of coronary
calcification, calcium scoring, 3D visualization) as a multi-slice CT scanner at
a fraction of the cost of a new machine. Thus, the Cardiac - 3D CT Software
product provides the option to the Radiology Departments of Hospitals, (when
funds are limited), to extend the life time of their single slice CT scanners by
acquiring a limited scope of cardiac and 3D imaging diagnostic capabilities. The
system is ready for installation. Training and Installation is included in the
retail price. The final product is offered by CANAMET as a PC-based unit that
requires as input the sinogram data from a single slice CT scanner. Image
reconstruction, detection of coronary calcification, calcium scoring, 3D volume
visualization, report-preparation and the various tools are included in
CANAMET’s PC-based unit. Final images are in DICOM format and they are
compatible with PACS systems.
Previously CT scans were impeded by subtle cardiac movements. With our technique cardiac motion artefacts can be removed to capture such previously undetectable things like the coronary calcification visible in the right image below.
Motion artefacts in the image to the far left result in no visibility of existing calcificaion. In the image to the right the arrow points to calcification which is visible due to the removal of motion artefacts.
Motion artifacts in the image to the far left, results in no visibility of existing calcification. In the image to the right the arrow points to calcification which is visible due to the removal of motion artifacts.
Motion artefacts in cardiac CT images are a serious problem. Due to these artefacts, a doctor or radiologist could be easily misled into identifying and detecting the calcification and is subjected to make erroneous diagnoses. Our motion correction software overcomes this problem and reconstructs motion artefacts free images.
3D Visualization from 2D Slices
The 2D images on left are generated from a conventional CT scanner. Many of these are stacked to produce 3D volume image on the right.

Old CT scanners produce 2D images of the slices through the body as opposed to the newer multi-slice CT scanners which produce the 3D volume image. Our 3D visualization software can use the parallel slices of the body (produced by old CT scanners) and assemble them together to produce 3D volume image. In this way, the capabilities of an old CT scanner can be enhanced to the most modern, state of the art CT scanner. Some features of the 3D visualization software are:
- Provides a user friendly 3D imaging display
- Ability to view the 3D object from different angles by rotating, turning and moving the object around.
- Ability to make ‘cuts’ at different locations of the volume to view the internal structure.
- Inside of the volume can be can be observed by altering the transparency of the object.
- Grey level adjustment (brightness, contrast etc) can help to enhance a selected structure.
- Three orthogonal planes through the volume can be viewed simultaneously.
- Zoom level adjustment (and panning) aids the viewing capability.
- Different measurements (length, area, angle etc) can be performed.
- Video recording function permits the creation of animated sequence of 3D volume.
Both images are made from multiple 2D slices produced from a conventional CT scanner. From volume visualization one can choose to produce images of hard bone or soft tissue surfaces.
