Reality (XR)-Assisted CT-Guided Localization
Full description
With the widespread use of computed tomography (CT), lung nodules detected through screening have become increasingly smaller. These small nodules are often hidden within the lung parenchyma, making them difficult to visualize or palpate during surgery. As a result, nodule localization techniques have become critically important and are heavily relied upon by thoracic surgeons. Currently, CT-guided localization is the standard approach; however, this requires patients to move between the CT suite, the ward, and the operating room, which is highly inconvenient.
An alternative is the use of a one-stop hybrid operating room, which integrates imaging and surgery in a single space, but this solution is costly. This study aims to enroll 20 patients in a pilot investigation of using extended reality (XR)-guided localization in video-assisted thoracoscopic surgery (VATS) for lung nodule resection. By leveraging current XR technologies, a digital twin model will be superimposed onto the patient's body. Our team-developed virtual localization technique will then be used to mark the tumor site with dye, enabling surgeons to precisely excise the tumor with minimal tissue removal.
If successful, this technology has the potential to replace traditional CT-guided or hybrid operating room localization, thereby reducing patient inconvenience and financial burden, and ultimately achieving a streamlined and cost-effective surgical workflow.
