Feature Highlights

Importing and Repositioning Model

Import your own custom heart models and reposition them in the physical space!

CardiacAR Model Import and Reposition

Panning, Scaling, and Perspective View

Using CardiacAR, you can pan, rotate, and scale the model for better angles. You can also move your device through the model by moving it in the physical space to obtain a perspective view of the model.

Model Slicing

Explore various cross sections of the model to beter understand the details of the heart model. Implement multiple slices and cross sections to narrow your field of view. Preview the slices before confirming them using the “Confirm Slice” button.

   abstract = { The current practice for planning complex cardiovascular surgeries includes printing
   and cutting physical heart models. Unfortunately, such cuts are permanent, thus it
   is not possible to interactively experiment with different cuts, slowing the planning
   process. In collaboration with Children’s Healthcare of Atlanta Heart Center (CHOA),
   we are exploring new ways to improve cardiovascular, or heart, surgical planning through
   augmented reality (AR). We are developing CardiacAR , an iOS AR application that enables
   interactive surgical planning on mobile devices. CardiacAR offers powerful and flexible
   tools critical for surgical planning, such as omni-directional slicing of patients’
   3D heart models and virtual annotation to assist planning. We believe the ubiquity
   of iOS devices will help broaden access to the CardiacAR technology and streamline
   its deployment.},
