Neurosurgical Navigation with Intraoperative Photoacoustics
Endonasal transsphenoidal surgery, an effective approach for pituitary tumor resection, poses the serious risk of internal carotid artery injury, which causes many severe complications, including patient death. This injury occurs because the current endoscopic approach is limited to visualization of superficial anatomy. We are developing the imaging technology needed visualize the carotid arteries hidden by bone and surrounding tissue and thereby eliminate the risk of injury. The concept for this intraoperative photoacoustic imaging technology includes an optical fiber attached to a surgical tool and a transcranial ultrasound probe placed on the temple, as demonstrated in the picture.
