Image-guided surgery, also known as computer-assisted surgery or surgical navigation, refers to a modern medical technique that employs advanced imaging technology to aid surgeons during complex surgical procedures. It involves the integration of real-time imaging data, such as computed tomography (CT), magnetic resonance imaging (MRI), or ultrasound, with the surgical instruments and patient anatomy.
The primary objective of image-guided surgery is to enhance surgical precision, improve surgical outcomes, and minimize potential risks and complications by providing surgeons with accurate and updated information about the patient's anatomy in real-time. This technology enables surgeons to navigate through delicate anatomical structures and locate specific targets during surgery with exceptional accuracy.
In image-guided surgery, a computer system analyzes the preoperative images and combines them with real-time tracking of the surgical instruments. It provides real-time feedback to the surgeon, frequently in the form of visual overlays on a monitor or a specialized display device. This feedback allows the surgeon to precisely position instruments, visualize the position of critical structures, and make informed decisions during the procedure.
Image-guided surgery finds applications in various medical fields, including neurosurgery, orthopedic surgery, cardiovascular surgery, and otolaryngology. It can assist in procedures such as tumor resections, joint replacements, spinal surgeries, and many others. By providing surgeons with detailed real-time information, image-guided surgery has revolutionized the field of surgical interventions, enabling safer and more precise surgical procedures.
