摘要:
A surgical instrument navigation system is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient. The surgical instrument navigation system includes: a surgical instrument; an imaging device which is operable to capture scan data representative of an internal region of interest within a given patient; a tracking subsystem that employs electro-magnetic sensing to capture in real-time position data indicative of the position of the surgical instrument; a data processor which is operable to render a volumetric, perspective image of the internal region of interest from a point of view of the surgical instrument; and a display which is operable to display the volumetric perspective image of the patient.

摘要:
Systems and methods described herein provide for generating disruptive recommendations based on a seed input. The viewer may receive recommendations having varying affinity between a media asset being currently viewed and the seed input. In some embodiments, the viewer interacts with a slider interface having the currently viewed media asset at one end and the seed input at the other, and an affinity indicator proximate to either end. The viewer may select a location of the affinity indicator on the slider for determining recommendations. The viewer may receive recommendations based on the currently viewed media asset and the seed input as the affinity indicator slides from one end of the slider interface to the other.

摘要:
Frequency-scanning interferometry is used for measuring test objects having multiple surface regions. The regions are distinguished and can be measured based on different measuring criteria. Interference data is gathered for the imageable portion of the test object from a plurality of interference patterns taken over substantially the same imageable portion at different measuring beam frequencies. The interference data is evaluated to determine topographical measures of associated points on the test object. The topographical measures are compared against a benchmark to distinguish between points on the test object that are within a first of the surface regions from points on a boundary separating the first surface region from one or more other surface regions of the imageable portion of the test object. The interference data of points within the first surface region are further evaluated to a higher accuracy.
