Latest Patents

Kolker holds a patent for "Methods for spectrally calibrating CT imaging apparatus detectors." This patent describes a method for calibrating a computed tomographic imaging apparatus that includes a gantry, a radiation source operable at a plurality of kVp's, and a detector array with multiple detector elements. The method utilizes a system detection function to estimate signals of each detector element that would have been detected through air and through a given thickness of water. These estimated datasets are crucial for determining data pair sets, which comprise a normalized water projection value and an ideal projection value for each detector element. Furthermore, the method involves determining and storing a mapping function of the normalized water projection values to the ideal projection values in the memory of the CT imaging apparatus, serving as a spectral calibration.
