January 2015 Accurate and efficient guidance of medical devices to procedural targets lies at the heart of interventional procedures. Ultrasound imaging is commonly used for device guidance, however, determining the location of the device tip can be difficult. Various methods
Ex vivo photoacoustic imaging of the human placenta
May 2015 Image guidance plays a central role in minimally invasive fetal surgery, such as photocoagulation of inter-twin placental anastomosing vessels to treat twin-to-twin transfusion syndrome (TTTS). Fetoscopic guidance provides insufficient sensitivity for imaging the vasculature that lies beneath the fetal
Photoacoustic imaging of the human placenta with ultrasonic tracking for TTTS
February 2015 Image guidance is a central component of minimally invasive fetal surgery for treatment of twin-to-twin transfusion syndrome (TTTS). The gold standard for treatment involves laser photocoagulation of anastamosing vessels on the fetal side of the placenta. In current
An interventional multispectral photoacousic imaging system for guiding minimally invasive surgeries
December 2014 Precise device guidance is important for interventional procedures in many different clinical elds including fetal medicine, regional anesthesia, interventional pain management, and interventional oncology. Whilst ultrasound is widely used in clinical practice for real-time guidance, the image contrast
