Application of an RGBD augmented C-arm for minimally invasive scoliosis surgery assistance
Healthcare Technology Letters, 2017 Minimally invasive surgeries (MISs) are gaining popularity as alternatives to conventional open surgeries. In thoracoscopic scoliosis MIS, fluoroscopy is used to guide pedicle screw placement and to visualise the effect of the intervention on the spine ...

Calcium Sensor for Photoacoustic Imaging
Journal of the American Chemical Society, 2017 We introduce a selective and cell-permeable calcium sensor for photoacoustics (CaSPA), a versatile imaging technique that allows for fast volumetric mapping of photoabsorbing molecules with deep tissue penetration. To optimize for Ca2+-dependent photoacoustic signal changes, we synthesized a selective metallochromic sensor with high extinction ...
