About rapid rescreening.

A correct diagnosis may reach the wrong patient because of a mix-up of either diagnostic specimens or identification data. It is astonishing how little attention is paid to this problem in medicine while the scale, the reach and the complexity of diagnosis are growing fast. More research is urgently needed to detect and investigate these types of errors. There is no quick remedy for this problem: a systems approach with comprehensive assessment of potential risks and subsequent management is the only sensible way out. Regrettably it is impossible to completely eliminate swapping errors, at best they can be reduced to an absolute minimum.

Correcting out-of-plane errors in two-dimensional imaging using nonimage-related information.

Two-dimensional imaging with a single camera assumes that the motion occurs in a calibrated plane perpendicular to the camera axis. It is well known that kinematic errors result if the object fails to remain in this plane and that if both the distance to the calibration plane from the camera and the distance out-of-plane are known, an analytical correction for the out-of-plane error can be made. Less well appreciated is that out-of-plane distance can frequently be acquired from other, nonimage-related information. In the two examples given, the mediolateral center of pressure coordinate of the foot measured from a force plate and the measured landing point of a shot put throw were used. In both cases, the resulting out-of-plane correction improved the accuracy of the 2-D kinematic data dramatically. These examples also demonstrate that the use of nonimage-related data can increase the accuracy of kinematic data without an increase in the complexity of the experiment.
