| 20120313001 | IMAGE SYNTHESIS APPARATUS AND IMAGE SYNTHESIS METHOD - Provided are an image synthesizing device and an image synthesizing method wherein a subject is less affected by beam absorption. A diffraction beam intensity and a front diffraction beam intensity actually detected are included in the influence of absorption on a subject (Sa). Yet, assuming that said beams have the attenuation rate which is caused by said beams being absorbed when passing through a subject, the angle of refraction θ | 12-13-2012 |
| 20130026383 | Method for Imaging Object Using Photoneutron Transmission and Detector Arrays Using the Same - A method for imaging an object by means of photoneutron transmission is provided, which comprises the steps of: collimating the photoneutron rays passing through the object by means of a neutron collimator so as to determine the position information of the photoneutron rays based on the position of the neutron collimator; detecting the collimated photoneutron ray beams by means of a detector module, wherein the detector module includes a neutron moderator and at least one thermal neutron detector located within the neutron moderator, wherein the neutron moderator converts the photoneutrons into thermal neutrons, and wherein the thermal neutron detector measures the thermal neutrons so as to obtain attenuation information of the photoneutron ray beams upon passing through the object; and integrating the position information and the attenuation information so as to form an image of the corresponding part of the object. The method determines the position of the photoneutron rays based on the position of a neutron collimator, so as to overcome the problem of incapability of imaging due to loss of position information of the photoneutrons during moderation thereof. The method also images the object by arranging detector module arrays. | 01-31-2013 |

| 20140151569 | METHOD AND APPARATUS FOR ANALYSIS OF SAMPLES - A method and a device examine a sample with radiation emitted from a radiation source, which is directed to the sample carried by a sample holder via a beam-forming unit and detected by a detector and evaluated in an evaluating unit. Prior to the examination of the sample, at least one of the following components, including the radiation source, beam-forming unit, sample holder, detector, and a primary beam stop, are oriented and/or positioned in terms of spatial location in relation to at least one of the other components and/or in relation to a predefined fixed point and/or in relation to the optical path with a control unit via actuating drives. The radiation intensity measured by the detector, in a predefined detector range, and/or a value derived therefrom is used for establishing a control variable conferred from the control unit to the actuating drives assigned to the components. | 06-05-2014 |
| 20160091440 | METHOD AND DEVICE FOR IMAGING AN OBJECT THROUGH PHOTONEUTRON TRANSMISSION - The application relates to a method and device for imaging an object through photoneutron transmission. The method uses photoneutron rays to transmit the object, and comprises the following steps: emitting photoneutron rays by a photoneutron source to irradiate on the object; receiving the photoneutron rays from the photoneutron source by a detector; and imaging the object based on the photoneutron rays received by the detector; wherein the detector can slow down and absorb the photoneutrons, and wherein the incidence direction of the photoneutron rays from the photoneutron source and the normal direction of the detector surface form an angle ranging from 60 degrees to 87 degrees, or from about 60 degrees to about 87 degrees. | 03-31-2016 |
| 20160161427 | HIGH ENERGY GRATING TECHNIQUES - Imaging techniques that may be used in applications such as differential phase contrast imaging are disclosed that include, for example, configuring a beam source and a beam detector such that a beam connects the two, positioning an object, a phase grating and an analyzer grating in the beam path, producing multiple data sets based on various analyzer grating positions, and conducting a regression analysis using a predetermined function having a set of fitting coefficients to establish those fitting coefficients. In those techniques, the fitting coefficients may be used to characterize a set of interference properties associated with the object. | 06-09-2016 |
