We are investigating the use of photoacoustic (PA) imaging to detect critical structures, such as the carotid artery, that may be located behind the bone being drilled during robot-assisted endonasal transsphenoidal surgery. In this system, the laser is mounted on the drill (via an optical fiber) and the 2D ultrasound (US) probe is placed elsewhere on the skull. Both the drill and the US probe are tracked relative to the patient reference frame. PA imaging provides two advantages compared to… Expand
Improving the safety of telerobotic drilling of the skull base via photoacoustic sensing of the carotid arteries
A new method for accurately determining the safe region for drilling, defined by the center-line between the two carotid arteries, is described and the first phantom experiments with this system are presented. Expand

Accuracy of a novel photoacoustic-based approach to surgical guidance performed with and without a da Vinci robot
This work proposes a novel approach to surgical guidance that relies on photoacoustic-based vessel separation measurements to assess the extent of safety zones during these type of surgical procedures, and indicates that with further development,photoacoustic image-based measurements of anatomical landmarks could be a viable method for real-time path planning in multiple interventional photoac acoustic applications.

Experimental assessment of energy requirements and tool tip visibility for photoacoustic-guided endonasal surgery
Endonasal transsphenoidal surgery is an effective approach for pituitary adenoma resection, yet it poses the serious risk of internal carotid artery injury. We propose to visualize these carotidExpand

Simulations and experiments confirm that an intra-operative configuration in which the photoacoustic signal is received by a pickup transducer from the anterior surface of the prostate provides the best approach to PAT acquisition. Expand
Localization of Transcranial Targets for Photoacoustic-Guided Endonasal Surgeries
Neurosurgeries to remove pituitary tumors using the endonasal, transsphenoidal approach often incur the risk of patient death caused by injury to the carotid arteries hidden by surrounding sphenoidExpand
Consistent evaluation of an ultrasound-guided surgical navigation system by utilizing an active validation platform
This paper evaluated an optical tracker-based surgical ultrasound-guided navigation system whereby the optical tracker tracks marker frames attached on the ultrasound probe and the needle, and designed a complete evaluation platform by utilizing the mid-plane detection and time of flight measurement systems.

Feasibility of transcranial photoacoustic imaging for interventional guidance of endonasal surgeries
Endonasal surgeries to remove pituitary tumors incur the deadly risk of carotid artery injury due to limitations with real-time visualization of blood vessels surrounded by bone. We propose to useExpand
Active point out-of-plane ultrasound calibration
This work presents the use of an active point phantom and a calibration framework that accounts for the elevational uncertainty of the point, and simulates in noiseless and noisy cases, results on out-of-plane estimation errors, calibration estimationerrors, and point reconstruction precision.

Active Echo: A New Paradigm for Ultrasound Calibration
For the first time, an active echo (AE) phantom is introduced for US calibration, which actively detects and responds to the US beams from the imaging probe and enables automatic point segmentations. Expand
Use of cranial surface anatomic fiducials for interactive image-guided navigation in the temporal bone: a cadaveric study.
Interactive image-guided navigation in the temporal bone is possible with registration of cranial surface anatomic fiducials and may be useful to the neurosurgeon and otologist in identifying critical anatomic structures of the temporalBone encountered during the translabyrinthine, retrolab Labyrinthine presigmoid, and suboccipital approaches.

Surgical complications associated with the endoscopic endonasal transsphenoidal approach for pituitary adenomas.
Overall, a decreased incidence of complications has been observed, compared with large historical series of the traditional microsurgical transsphenoidal approach, likely because of the overview inside the anatomy facilitated by the endoscope, and the decreased surgical trauma. Expand
