... directions to be isolated. An electromagnetic tracking system is used for position tracking. Two prototypes of the sensorized instrument were constructed. Position calibration shows a maximum root mean square (RMS) error of 1.3 mm. The results of the force calibration show a maximum RMS error of 0.35 N...

...Alexander H. Slocum, Jr.; Stephen E. Jones, MD; Rajiv Gupta, MD A calibration phantom that can be used to measure the temporal resolution of a CT scanner was designed utilizing a deterministic design process. The system was first defined in terms of a set of functional requirements based...

... ∕ μ m , or apparent elastic modulus of 40 MPa – 1.80 GPa ). Finite element analysis (FEA) was used to calculate the rigidity of each RB and was validated with physical testing in a universal testing machine. Results from FEA were then used to calibrate the system and relate force, piezoelectric...

...Alexander H. Slocum, Jr.; Stephen E. Jones; Rajiv Gupta This paper describes the design and development of a calibration phantom to be used to aid in the calculation of the temporal resolution of tomographic imaging devices. Current practice for characterizing the dynamic response of a tomographic...

...-tissue compliance meter. Our motivation was to improve the compliance realism of our virtual haptic back model, but there are many potential applications for this method. We present calibration of the haptic interface, pseudostatic compliance measurement techniques, measurement of contracted muscle...
