   With a better understanding of a child's unique heart defect, surgeons could improve the recovery time and quality of life for children with complex conditions that may need multiple surgeries spread over the years, said Ajit Yoganathan, co-principal investigator on the project and a professor of biomedical engineering at both Georgia Tech and Emory University in Atlanta.
   
   The technology, known as image-based surgical planning, creates a three-dimensional model of the child's heart using data from a series of MRIs taken at different times in the child's cardiac cycle.The series is called a four-dimensional MRI.
   
   "We use the MRI images and time data to create models of these children's vascular systems and hearts to simulate how they currently work, and how they could work after surgery," Yoganathan said.
   
   The models allow surgeons to visualize the direction of blood flow and determine any energy loss in the heart.So if a surgeon were planning a certain correction to an area of a child's heart, the model would show the surgeon how well blood would flow through the newly configured heart after surgery, Yoganathan said.
   
   The researchers' eventual goal is to include a postoperative evaluation of the heart's performance by using sophisticated blood flow computer simulation.
   
   While the program isn't yet ready for use by surgeons outside the project, it could be available in about three to five years, Yoganathan said.

   "We use the MRI images and time data to create models of these children's vascular systems and hearts to simulate how they currently work and how they could work after surgery," said Ajit Yoganathan, Ph.D., a co-principal investigator on the project and associate chair of the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University."The goal is to improve the quality of life for these children by understanding their current physiology and finding the best way to optimize the surgery for that particular child".
