Ginavan manages new and pre-existing televideo sites throughout Kansas, including the newest Kansas Video Network.
Since the inception of the program in 1991, this network has been host to over 13,000 clinical consultations, covering a range of 300 specialties.
Ginavan has incorporated several different pieces of software into his production department, but notes the addition of 3D animation has really allowed his presentations to stand out from the field. Recently, he was awarded 1st Place honors in the Open Industrial/Educational section of the KAN Film Festival for his film "Understanding Deep Brain Stimulation". For the film "Understanding Deep Brain Stimulation", Ginavan, who wrote, directed and produced, interviews doctors and advanced practice nurses who explain the process to prospective patients in this 25-minute movie. To illustrate some of the concepts and procedures described by the doctors, Ginavan created 3D animations. He credits his success, in part, to the 3D medical animations he was able to create for the film. This film was not his first, nor is it his latest.
Although Ginavan admits to having used the software since version 5, he still remembers the first time he used Cinema 4D. He recalls, "[The] learning curve is short, and with so many tutorials to work through, you can often times adapt tutorials to help with a specific client's project..."
High Frequency Deep Brain Stimulation (DBS) involves a micro-stimulation of specific parts of the brain, requiring unique animation in the production. Specifically, DBS is a surgical procedure involving the connection of a wire to the patient's brain to a pacemaker-like device which is placed under the skin, on the chest. The device electrically stimulates specific parts of the brain. This is believed to either reduce over-stimulated areas, or bring the brain activity back to normal. The device can later be programmed to adapt to the amount of brain stimulation necessary.
The surgery for DBS requires a hole to be cut in the top of the skull. A frame is attached to the head that helps doctors map different areas of the brain to MRI sequences taken with the device in place. The MRI information is also used to plan out the best course for laying the wire that will act as a stimulus. Because the patient is awake, the actual nerve cell's electrical impulse can be heard. Sometimes the sound of the impulse will fire as the same time as the patient's tremor.
Using the amplified signal of the nerve's impulse can be used to fine tune the location of the DBS stimulus electrode.
After the brain surgery is complete, a pocket is made under the skin to allow the wire lead to run from the brain to the triggering device that is placed under the skin, over the chest.
When the surgical procedures are complete, patients will have their stimulation devices programmed several times, sometimes lasting over the course of several months. The initial programming alone takes 4-5 days. Because no two Parkinson's patients suffer the same physical tremors, stimulation needs to be fine tuned, sometimes over several visits, to ensure that the patient specific symptoms are addressed. Different combinations of stimulation programs are necessary for each patient.
Ginavan's footage of patients' progress at The Parkinson's Disease and Movement Disorder Center is truly breathtaking. The film does not over-simplify the procedure, but makes it understandable, for patients, friends and family. Even the casually interested viewer, will take away an appreciation for the inspiring effect that DBS has for patients with Parkinson's disease, Essential Tremor or dystonia.
Ginavan remarks, "The before and after effects of DBS on many patients are profound. Jaw droppingly profound. The end of the film has a few of these before and afters and they are truly astonishing." Including audiences of patients, technicians and doctors; specific parts of his film have reached television audiences around the country, airing on medical and news programs.
There continues to be a growing need for medical animations. As KUMC's therapies on DBS develop, successful methodologies will have to be recorded.
Producer, director, and self-proclaimed "scifi geek", Dan Ginavan continues to work with MAXON's Cinema 4D software to produce character animations at the University of Kansas Medical Center and at home in his spare time, and teaches computer animation at Kansas City?s Art Institute / Continuing Education Department.

Congratulation on your Film Festival award for your film, "Understanding Deep Brain Stimulation." Thank you so much for taking us on a journey into your world. The research on this project was obviously intense understanding the limits [or limitlessness] of the C4D program and combining it with the knowledge and complications of the brain is truly genius at work the perfect blend of art, technology, and humanity.
Wow, I guess I timed out and have to redo the message. I am impressed with your work here. I am starting up a medical illustration deal for trial lawyers (because I am one) and using Poser (yes, Poser) and SoftImage XSI, and Bryce, and Amorphium, and Electric Image Universe, and any other app that works for the task. I'm working with an M.D. who is also a graphic artist and he's a MAC guy. I'm a PC person. We are having a debate on what app to use for a finalization process. Since most of the good stuff is PC only or MAC only, we have to chose something that works for both of us. In the running is LW, Maya, and Cinema. Not necessarily in that order. Having met Paul Bobb, CEO of Cinema, and having learned that 90-95 percent of the code is machine language and 10-5 percent is operating system usage, I am deeply impressed with Cinema. This is very interesting what you did with Cinema. Certainly worth look carefully at. Best wishes, keep up the good work.
This is a wonderful article and so timely as well. Than You so very much Ko Maruyama for this well written piece.
OMG! I wish I could afford to have Dan help me on my latest project. I have a presentation to give before the local chapters of American Society of Civil Engineers (ASCE) and the Society of Automotive Engineers in Las Vegas Nevada on June 15th, 2005. The is "Alternative Energy through Resource Reclamation: Engineering the Infrastructure of a Sustainable Economy" Oh well, one can always wish...
