Magnetic Resonance Imaging (MRI) provides both anatomical imaging with excellent soft tissue contrast and functional MRI imaging (fMRI) of physiological parameters. The last two decades have witnessed the manifestation of increased interest...
Non-Contact Photoacoustic Imaging Using a Commercial Heterodyne Interferometer [0.03%]
基于商用外差干涉仪的无接触式光声成像方法研究
Chao Tian,Ting Feng,Cheng Wang et al.
Chao Tian et al.
Most current photoacoustic imaging (PAI) systems employ piezoelectric transducers to receive photoacoustic signals, which requires coupling medium to facilitate photoacoustic wave propagation and are not favored in many applications. Here, ...
Shape Tracking of a Dexterous Continuum Manipulator Utilizing Two Large Deflection Shape Sensors [0.03%]
基于两个大挠度形状传感器的灵巧 continuum 机械手形貌跟踪研究
Hao Liu,Amirhossein Farvardin,Robert Grupp et al.
Hao Liu et al.
Dexterous continuum manipulators (DCMs) can largely increase the reachable region and steerability for minimally and less invasive surgery. Many such procedures require the DCM to be capable of producing large deflections. The real-time con...
Biocompatible Pressure Sensing Skins for Minimally Invasive Surgical Instruments [0.03%]
