摘要
An apparatus for image reconstruction is provided, including processing circuitry to obtain, from a scan of a region of interest of a patient, raw projection data of the region of interest; reconstruct the raw projection data to produce image data; apply high dynamic range tone-mapping to the image data to produce tone-mapped image data by applying window width and window level parameters to the image data to produce adjusted image data, and calculating a contrast adjustment based on both the image data and the adjusted image data; and quantize the tone-mapped image data to produce quantized tone-mapped image data for display.
