New York-based BioDigital Systems uses CG |

On a typical Friday Aaron Oliker is often in one of the operating rooms at New York University’s medical school, standing alongside a sur- geon observing intently as a knee re- placement is started or as a heart sur- gery is completed. Oliker witnesses pro- cedures performed by some of the coun- try’s most talented physicians as part of his research for creating some of the most anatomically accurate 3D medical simulations available. “To be able to do the animations, you have to know the surgeries just as well as the doctor,” says Oliker, technical director of 3D simulations and partner in BioDigi- tal Systems, a New York city-based com- pany that specializes in creating every- thing from 3D simulated surgical training |

Seven years later, Oliker is using his skills and combining his abilities with those of partners John Qualter, a medical animator who heads BioDigital Systems’ animation division, and Frank Sculli, a bio- medical engineer who leads the compa- ny’s informatics department (who gath- ers and plugs the data into the programs), to create peer-reviewed products that are on the cutting edge of technology for a range of clients that include hospitals, pharmaceutical and medical device com- panies and medical schools. |

To create a stem cell animation that explains how using stem cells af- fects the brain for Stem Cell Therapeutics, a small Canadian biotech firm, the team used real data from Magnetic Resonance Imaging (MRI) scans to create the animated brain. |

| tools to animations that show how drugs work to databases for cancer institutes. “You have to see it, and when you create it, it has to be right because [these ani- mations are] what people will be using to train with.” Oliker began observing procedures while working on a training DVD that launched his career in 3D medical visualization. In 1999, he became involved with SmileTrain a charitable organization that provides free cleft palate surgeries to children who would otherwise not receive care. Working with Dr. Court Cutting, he developed an animated CD-ROM to show doctors in Third World countries how to perform the surgeries. He created Maya plug-ins to im- |
To create their nonfiction 3D visualiza- tions, Oliker, Qualter and their respective teams use the same tools as a Hollywood animator: After Effects and Combustion for compositing; Mental Ray for rendering and Photoshop for texturing. Maya is the, backbone for the firms’s 3D animations,but they’ve created plug-ins specifically for medical animation, as well as proprietary technology and techniques that are used to import real-time data and accelerate processes.

The company’s prod- ucts take anywhere from two weeks to sev- eral months to create and can cost $10,000 and up depending on the length of the project, and exactly what's involved. Often, for medical centers and teaching hospitals, the company works with money from grants used to develop these tools. Qualter is currently working on a project with New York University School of Medicine called Web Initiative for Surgical Education (WISE-MD) where he is creating |

used to give third-year medical students
an overview of different surgical
procedures. “We have video
footage of surgeries, and we create
animations of surgeries and sync
the animations to the video,” explains
Qualter, who also often observes
surgeries in order to animate
them. “Students can log on the
night before to see a particular proprocedure
so everything is clear to them.
[They’re looking] at a bloodless field, it’s
colorful and we label the structures
they’re seeing, so when they look over the
shoulder of a doctor, they’re not so lost.” Originally created as a teaching tool for NYU, the project has gained national interest and educators are looking at ways to incorporate digital learning into curricula. With consistently improving technologies in such as nascent field, applications are constantly developing, even outside the scope of medicine and into related fields like law and criminal justice.

But for now the biggest challenge is educating their future clients physicians, hospitals and other health care providers about what these 3D visualizations can do, especially in an industry that is slow to adapt to technology. “When people read something, it’s an effective training tool, but to see something it’s a much better learning device,” says Oliker. “The more people see these animations, the more people will see the value of 3D medical visualization and how it can be used to educate, plan surgeries or create new procedures. |
