Techniques are provided for generating three-dimensional images, such as may be used in mammography. In accordance with these techniques, projection images of an object of interest are acquired from different locations, such as by moving an X-ray source along an arbitrary imaging trajectory between emissions or by individually activating different X-ray sources located at different locations relative to the object of interest. The projection images may be reconstructed to generate a three-dimensional dataset representative of the object from which one or more volumes may be selected for visualization and display. Additional processing steps may occur throughout the image chain, such as for pre-processing the projection images or post-processing the three-dimensional dataset.

A high contrast high resolution display is produced using an image chain comprising a plurality of downstream high resolution modulators. The modulators may be illuminated by a locally dimmed backlight. Polarization control is maintained throughout the image chain via reference and analyzing polarizers combined with non-depolarizing layers. The modulators are grayscale and modulate at the sub-pixel level. A color panel may be maintained for embodiments that require color. Diffusion in the chain is matched to a resolution of the image content carried in the light such that the effects of local dimming and sub-pixel resolution are preserved. Brightness enhancement films may be utilized to enhance brightness and maintain polarization control.

An image browsing method, system and computer storage media are disclosed. The method includes: obtaining a user's operation request for an image; comparing the operation request with a preset condition, and determining whether to cache the image into a main cache. When it is required to cache the image into the main cache, further determining whether it is the first time that the image is rendered; if yes, employing a main thread to cache the image into the main cache, to obtain the image from the main cache, and to render the image. Otherwise, employing a main thread to obtain an image adapted to the capacity of the main cache from an image chain, and to render the image; and displaying the image rendered. This avoids unsmooth browsing of the image due to time-consuming creation of the images to be rendered, thereby allowing smooth image browsing.
