A system and method for dynamic zoom adjustment based, in part, upon: the raster data in the user selected local area is disclosed; and / or the knowledge of a prevailing font size in a user selected region such that the text in that region is enlarged to be just readable. To achieve this, the detail in the local area is examined and a zoom factor is calculated that depends on the image detail and / or the viewing screen resolution. A document server may be employed to develop the information needed to enable this functionality. In one embodiment, the information is developed by RIPping the document, and then storing a spatial map of localized details (e.g., font sizes at several display resolutions) to automatically adjust a zoom level or factor and thereby facilitate navigation and reading.

A method and system for displaying predictions on a spatial map includes using a data analyzer for analyzing heterogeneous data having a spatial component to find utilizable data and using machine learning to automatically extract relationships from the utilizable data. The extracted relationships are used to make a prediction about at least one location on the spatial map and present that prediction in an oblique or perspective view.

A system and method of dynamically localizing a measurement of parameter characterizing tissue sample with waves produced by spectrometric system at multiple wavelengths and detected at a fixed location of the detector of the system.

A medium of interest is interrogated according to ultrasound elastography imaging. A preliminary elasticity-spatial-map is formed. This map is calibrated against a reference elasticity-spatial-map that comprises an array (232) of different (240) elasticity values. The reference map is formed to be reflective of ultrasonic shear wave imaging of a reference medium. The reference medium is not, nor located at, the medium of interest, and may be homogeneous. Shear waves that are propagating in a medium are tracked by interrogating the medium. From tracking locations on opposite sides of an ablated-tissue border, propagation delay of a shear wave in the medium and of another shear wave are measured. The two shear waves result from respectively different pushes (128) that are separately issued. A processor decides, based on a function of the two delays, that the border crosses between the two locations. The calibrated map is dynamically updated and may include post-ablation border expansion (346) and time-annotated previous stages (344, 348).
