Akira Dezawa M.D., Ph.D. shares his thoughts on our innovative Sony 4K monitors and groundbreaking A.I.M.E technology.
Dr. Akira Dezawa describes his experience with 4K and A.I.M.EQ. Tell us about the surgery you performed today.
Dr. Dezawa: A young patient aiming to be a professional athlete had a herniated disc between the 5th lumbar vertebra (L5) and sacrum. We performed minimally invasive endoscopic surgery so he can return to work quickly and continue to play sports.
Q. Could you explain a bit more specific about the Percutaneous Endoscopic Lumbar Discectomy (PELD)?
Dr. Dezawa: PELD is a minimally invasive surgery to remove herniated tissue using a spinal endoscopy. With PELD 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.
Dr. Dezawa: The herniated tissue to be removed is right next to irreproducible nerves. If you fail to recognise the position of the herniated tissues and the nerves, there is a risk that the patient could remain impaired. It’s essential to have a clear idea of their positional relations. Before the surgery, I usually simulate the procedures in three dimensions in my head based on my past experiences. It’s crucial that the image on the monitor we check during the surgery should be same as the simulation. The image quality makes a real difference to PELD.
Dr. Dezawa:To recognise slow tissue movement and judge whether it’s a nerve are really important as a surgeon. 4K has a clear advantage in grasping tiny movements of blood vessels and other surrounding tissue and allows us to view the tissue with a far better sense of depth.
Although it takes a long time to educate young professionals in this field, I expect that the kind of high-quality 4K image would be very useful in mastering a skill in a short time.
Q. Our A.I.M.E.™ (Advanced Image Multiple Enhancer)* function delivers rapid enhancement of contrast and colour, transcending conventional edge enhancement by offering enhanced views of entire structures. How does A.I.M.E. benefit you?
Dr. Dezawa: When we turn A.I.M.E. 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.
“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.”
“In this example, A.I.M.E. seems to improve the overall red contrast, so that the image may be easier to view.”
