Abstract: Photoacoustic medical-device navigation systems and methods provide alternatives to those incorporating fluoroscopy for medical-device navigation in patient bodies. A medical-device navigation system can include an optical-fiber stylet, ultrasound transducers, and a console. The stylet can transmit light to an instant location of a distal tip of an elongate medical device in a patient's body and, thereby, irradiate endogenous chromophores to generate ultrasound-frequency photoacoustic pressure waves therefrom. The ultrasound transducers can detect ultrasound signals corresponding to the photoacoustic pressure waves. The console can instantiate medical-device navigation processes for navigating the elongate medical device via the stylet as the elongate medical device is advanced to the target location in the patient's body.

Abstract: The systems and method described herein can generate guidance images that can indicate the real-time position of a medical device within an anatomical target. For example, the images can be high-resolution, 3D holographic renderings of a catheter (an example medical device) within a patient's heart (an example anatomical target). The guidance system can generate images that include computer generated (CG) images or models of the medical device and target anatomy. The guidance system can generate the CG images of the target anatomy from pre-operative images of a first modality, such as CT images or MR images. The guidance system can determine real-time placement position of the medical device from an intra-operative image of a second modality, such as fluoroscopic images.
