  • Patent number: 8340383
    Abstract: A CT scanner which can reconstruct high-quality tomographic images using only the projected images obtained by scanning an object without requiring any special three-dimensional phantom is provided. A two-dimensional radiation sensor placed to face a radiation source via the object acquires projected images while relatively rotating the object in the radiation emitted from the radiation source. Tomographic images are obtained at one predetermined slice position of the object by performing, for each of geometrical calibration parameter values, reconstruction of a tomographic image of the object using one of the calibration parameter values based on acquired projected images. One of the calibration parameter values is selected based on the obtained tomographic images. A tomographic image is reconstructed at each slice position by using a selected calibration parameter value based on a projected image at each acquired slice position of the object.

  • Patent number: 8229067
    Abstract: A radiation imaging apparatus comprises a radiation detection unit that detects radiation, an instruction unit that issues a radiation-imaging start instruction, and a setting unit to set an irradiation delay period that extends between the issuance of an imaging start instruction and the time irradiation begins. A first acquisition unit acquires a plurality of dark current images during the set irradiation delay period, and a second acquires a radiation image of the object after the end of the set irradiation delay period. A correction data generation unit generate correction data for the acquired radiation image, based on the dark current images, and a correction unit executes dark current correction processing of the acquired radiation image using the correction data.
