Dynamic Reconstruction and Rendering™ Features

Real Time Tomography's Dynamic Reconstruction and Rendering (DRR) technology is currently being applied to digital breast tomosynthesis, a new 3D imaging modality that has shown to have greater sensitivity and specificity than projection mammography in the early detection of breast cancer.  Some of the distinguishing features of DRR are highlighted below.

DRR can reconstruct images to the full resolution of the display at the specified magnification.

This DRR image was reconstructed at 3 times the magnification level of the image to the left at the full pixel resolution of the display.  Finer details of the spiculated mass with a calcification are displayed.

With DRR, the plane of reconstruction can be angled for better viewing of the image data.

This DRR tomosynthesis image was reconstructed to the specified magnification setting.  A calcified vessel (indicated by the arrow) is shown in the plane of reconstruction which is parallel to the detector.
 

This DRR tomosynthesis image was reconstructed with the plane of reconstruction tilted at an angle of 2 degrees to the plane of the detector.  More of the calcified vessel is displayed.

DRR can reconstruct and display tomosynthesis images to enhance breast tissue density and lesion conspicuity in real-time .

DRR can reconstruct and display volume renderings of variable thickness (i.e. slabbing).

Magnified view for the same region of interest as breast image on the left but for a  5 mm thick volume or slab.  The image clear displays a greater number calcifications  in the cluster that are distributed through the volume.
