1. A method for interactive adjustment of intensity window thresholds for display of a nuclear medicine image, the method comprising:
(a) accessing, by a processor of a computing device, the nuclear medicine image, said image comprising a plurality of pixels each having an intensity representing a level of a detected signal;
(b) rendering, by the processor, the nuclear medicine image for graphical display according to an initial intensity window, said rendering comprising 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) causing, by the processor, 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) receiving, by the processor 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 user selection of the subsequent intensity window, rendering, by the processor, for graphical display, the nuclear medicine image according to the subsequent intensity window, said rendering comprising 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) causing, by the processor, 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.
