Claim 12:
13. A system for interactive adjustment of intensity window thresholds for display of a nuclear medicine image, the system comprising:
a processor of a computing device; and
a memory having instructions stored thereon, wherein the instructions, when executed by the processor, cause the processor to:
(a) access the nuclear medicine image, said image comprising a plurality of pixels each having an intensity representing a level of a detected signal;
(b) render, for graphical display, the nuclear medicine image according to an initial intensity window using a set of available colormap values to visually represent the pixel intensities such that the full range of available colormap values are allocated to a subset of the pixel intensities that range from a minimum threshold of the initial intensity window to a maximum threshold of the initial intensity window;
(c) cause display of a graphical control element allowing for user selection of a subsequent intensity window, different from the initial intensity window, via user adjustment of one or more displayed indicator widgets from which one or more thresholds of the subsequent intensity window are determined, wherein the displayed indicator widgets are adjustable along a scale having increments that map to intensity values via a scaling function, wherein, for at least a portion of the increments, the scaling function is nonlinear;
(d) receive a user selection of the subsequent intensity window corresponding to an adjusted position of the one or more displayed indicator widgets of the graphical control element;
(e) responsive to receipt of the subsequent intensity window, render, for graphical display, the nuclear medicine image according to the subsequent intensity window using the set of available colormap values to visually represent the pixel intensities such that the full range of available colormap values are allocated to a subset of the pixel intensities that range from a minimum threshold of the subsequent intensity window to a maximum threshold of the subsequent intensity window, thereby creating an updated rendering; and
(f) cause display of the updated rendering from step (e) thereby dynamically updating display of the nuclear medicine image as the user adjusts selection the one or more displayed indicator widgets for selection of the subsequent intensity window.
