Abstract
A method and imaging system for operating imaging computed tomography using a radiation source and a plurality of detectors to generate an image of an object. The method includes: defining a desired image characteristics; and performing calculations to determine the pattern of fluence to be applied by the radiation source, to generate said desired image quality or characteristics. Then, the radiation source is modulated, to generate the intended pattern of fluence between the beam source and the object to be imaged. The desired image characteristics can comprise at least one of desired levels of contrast-to-noise ratio (CNR) and signal-to-noise ratio (SNR), and may provide at least one of: desired image quality in at least one defined region of interest; and at least one desired distribution of said image quality.
