A method for interactive natural language query processing includes receiving a natural language query comprising a plurality of words. The system includes a calibrated pyrometer for determining a first temperature of a Region of Interest under a first condition, and an uncalibrated thermal imager for determining a first average count value over the region of interest under the first condition and for determining a second average count value over the region of interest under a second condition. Preferably, the shrinkable layer comprises an array of fibers or nonwoven web comprising fibers having latent spiral crimp. The data set includes data acquired at two or more echo times per repetition and an element in the data set is sampled two or more times as a function of a non-Cartesian trajectory that crosses itself at least once. The magnetic dimensions of the head are found using the track profile obtained by the method.
