Application to production of attenuation graph of contrast of 3D image and treatment of the reconstruction which improves resolution, and the said treatment of the target

摘要

(57) Abstract This invention three dimensional image of the target (I3D) is something regarding the treatment of reconstruction, at the time of arraying the element of 3 dimensional image of the target, by the value to which the target it is defined (1) is thought the proper from property, consists of those below: The projection which can by the measurement of the - said target (PM) it decides, 3D image of the - said target is reconstructed with the iteration below: a) reconstruction of first 3D image of the said target is run, the local parameter which it defines b) as one function of the 3D image which the model of anisotropy of the said target, was reconstructed is estimated, the projection which was required c) by, the calculation of the property which at least passes one element is inferred, d) in order to infer the difference due to projection, the projection which was required by one calculation at least (E1), it compares with the projection which was required by measurement, e) the element of the significance attaching is decided, f) update of each element (E2) it does, g)At least, above-mentioned c) from f) step is iterated again. Application to medical application image field.
