    Abstract: A method comprises: acquiring imaging data using a tomographic radiological imaging apparatus (10); updating a calibration (42, 52) based on current information about the imaging apparatus; calibrating the imaging data using the up-to-date calibration; and reconstructing the calibrated imaging data to generate an image. The updating may be based on a current state of an idle or parked imaging modality that is not used in acquiring the imaging data, or on a measurement acquired together with the imaging data, or on the imaging data itself. For cone-beam computed tomography (CBCT) imaging data, the updating may comprise determining an intensity scale based upon intensity of at least one air pixel measured during the acquiring of the CBCT imaging data and updating an air scan template (60) by the intensity scale.

    Abstract: When correcting for artifacts on an attenuation map caused by an artifact source in a computed tomography image, nuclear images are reconstructed two or more times, each time using a different correction technique or uncorrected attenuation data. Corresponding voxels in the reconstructed images are compared to identify local areas that change, i.e., are fragile and therefore low-confidence, and areas that do not vary or exhibit little variance among the plurality of reconstructed images and are thus accorded a higher confidence. The reconstructed nuclear image is overlaid with color encoding indicative of the amount of confidence accorded to each voxel value obtained by attenuation-corrected tomographic reconstruction.
