GPU Based Real-Time Instrument Tracking with Three Dimensional Ultrasound
Real-time 3D ultrasound can enable new image-guided surgical procedures, but high data rates prohibit the use of traditional tracking techniques. We present a new method based on the modified Radon transform that identifies the axis of instrument shafts as bright patterns in planar projections. Instrument rotation and tip location are then determined using fiducial markers. These techniques are...
متن کاملReal-Time GPU-Based 3D Ultrasound Reconstruction and Visualization
Ultrasound scanning is frequently used in medical practice because it is a noninvasive, safe and low-cost solution (vs. CT or MR). However, conventional ultrasound probes only provide 2D scans. 3D ultrasound reconstruction builds 2D scans into 3D volumes of the patient’s internals. Since these volumes can be used for acquiring out-of-angle views, 3D rendering of the anatomy, and for image guide...
متن کاملGPU based real - time instrument tracking with three - dimensional ultrasound q Paul
Real-time three-dimensional ultrasound enables new intracardiac surgical procedures, but the distorted appearance of instruments in ultrasound poses a challenge to surgeons. This paper presents a detection technique that identifies the position of the instrument within the ultrasound volume. The algorithm uses a form of the generalized Radon transform to search for long straight objects in the ...

متن کاملUltrasound goes GPU: real-time simulation using CUDA
Despite the increasing adoption of other imaging modalities, ultrasound guidance is widely used for surgical procedures and clinical imaging due to its low cost, non-invasiveness, and real-time visual feedback. Many ultrasound-guided procedures require extensive training and where possible training on simulations should be preferred over patients. Computational resources for existing approaches...
