Optical Coherence Tomography (OCT) is a procedure used during cardiac catheterization. Unlike other ultrasound that uses sound waves, OCT uses light to produce images of the heart's blood vessel. With OCT, doctors can capture images of the vessels.

Dr. Passey has the required equipment to conduct OCT without any hassle. The technique gives instant HD pictures. However, our doctors need not require a microscope post-OCT as it gives an insight into heart vessels quickly.

For OCT, our doctors make sure to produce near-infrared light to create multiple images. For conducting OCT, A beam of light is infused into the artery. While some of these lights scatter, some of them reflect giving an instant HD picture.

Sometimes, the scattered light causes glare. However, the doctors filter out these glares to avoid any image disturbance.
