key features covered by this talk are, choice of transducers and needles; patient positioning; joint injections and aspirations; tendon sheath injections; cyst aspirations; biopsies.

Effective evaluation of positioning methods in order to give fair results when comparing different positioning technologies, requires performance measurements applicable to all the positioning technologies for mobile positioning. In this paper, we outline and compare five major performance measures namely, accuracy, reliability, availability, latency, and applicability, and how they apply to po...

Inertial sensors are widely used in various applications, such as human motion monitoring and pedestrian positioning. However, inertial sensors cannot accurately define the process of human movement, a limitation that causes data drift in the process of human body positioning, thus seriously affecting positioning accuracy and stability. The traditional pedestrian dead-reckoning algorithm, which...

A micro-assembling task using an image-servo positioning system is studied in this work. To improve the micro-assembling efficiency using manual operations, an image-servo automatic assembling system is established using a XYQ stepping positioning stage with a self-developed image recognition system. The circle outlines and the cross marks of the micro parts are used for this proposed system to...
