We interview Dr. Dezawa - a frontier surgeon for the latest treatments for lumbar herniated discs - about how AIME technology visibly improves surgical imagery.
Note: A.I.M.E. delivers rapid contrast and colour enhancement of input images. Its effectiveness in clinical situations has not been officially verified. (It was not designed to serve as a medical diagnostic or treatment tool.)
Dr. Akira Dezawa describes his experience with A.I.M.EThe endoscopic camera system used at my clinic is equipped with leading edge image processing technology designed by a European manufacturer. Today I am using Sony’s surgical monitor to compare some still images from our endoscope.
Let me start by saying that the monitor itself is very bright and very clear. And when we turn A.I.M.E.* (Advanced Image Multiple Enhancer) on, I can see that it compares very favourably with our own images. In particular, the A.I.M.E.-enhanced images are very bright, and the areas of interest to me—as a surgeon—are very clear and easy to see.
I also notice that, even in cases where the endoscopic camera was focusing on the foreground, the areas further back—that you would expect to be out of focus—are clear as well. I think this would probably reduce the need to move the camera around during surgery.
Dr. Dezawa says:
With A.I.M.E. turned off, the image is watery and blurred. When you turn A.I.M.E. on, the entire area seems to gain focus. In addition, I think the A.I.M.E. contrast enhancements may make the image easier to read.
Dr. Dezawa says:
In this example, A.I.M.E. seems to improve the overall red contrast, so that the image may be easier to view.
This time I only looked at some still images, but what I have seen seems extremely interesting. I think the (A.I.M.E) imaging technology might additionally be quite useful for other clinics, whose endoscopic cameras might not be as up-to-date as our clinic’s - since these enhancements can provide a significant improvement in imaging quality. Next time I would like to evaluate this (LMD-2765MD) monitor during real surgery.
Director of Dezawa PED Center; Visiting Professor of Orthopaedic Surgery at Teikyo University Medical School’s Mizonokuchi Hospital
After graduating from Chiba University Medical School in 1980, Dr. Dezawa served successively as the director of orthopaedic surgery at Yokohama-higashi National Medical Centre, Chief of Outpatient Centre at Chiba City Ryõiku Centre, Lecturer in Orthopaedic Surgery at Teikyo University Medical School, and Associate Professor of Orthopaedic Surgery at Teikyo University Medical Centre’s Mizonokuchi Hospital.
In 2004, he was appointed full professor and head of orthopaedic surgery at Teikyo University. In 2005, he also began a role as advisor to Mizonokuchi’s Deputy Directory.
Dr. Dezawa specialises in spinal surgery, hip joint surgery, electrophysiology, and minimally invasive surgery. In 2003, he introduced the use of Percutaneous Endoscopic Discectomy (PED)* in Japan and, continues to achieve excellent results with this procedure. He started the Dezawa PED Centre in 2014. He has also started a PED research group - and participates actively in research and dissemination of the procedure.
*What is PED?Dr. Dezawa introduced Percutaneous Endoscopic Discectomy (PED) to Japan in 2003. This minimally invasive procedure for the correction of disc herniation and lumbar spinal stenosis has significantly reduced recovery time, offering patients a much more rapid return to normal life and work.
Dr. Dezawa says, “Endoscopic procedures for accessing internal areas place much less stress on the patient than conventional methods. With PED, we only need to make an 8-mm incision. This means that the patient can leave the hospital on the same day as the procedure, and can return to work in as little as two or three days. This is particularly good news for patients who are reluctant to take much time off from their jobs. And because the incision is small, recurrences of the hernia are much less likely than with conventional surgery.”
