Disposiu00c7u00e7o X-ray to representau00c7u00e7o images of an object of examination and use of X-ray disposiu00c7u00e7o

摘要

The present invention relates to representation of high contrast of small lesions or other areas of target tissue in the human body, which contains at least one chemical element, contrasting, is described by a provision of X rays, which comprises at least one radiation source radius S x, which emits X-ray radiation substantially polychromatic,A first detector or several first detectors, which are determinable values of a first intensity of X-ray radiation transmitted by the object of examination, a second detector or detectors several seconds, which is determinable from a second intensity values D. The X-ray radiation emitted by the object of examination, at least one unit of correlation.With which they are correlacionu00e1veis first intensity values of the X-ray radiation transmitted image element for image element, with the second intensity values of the X-ray radiation emitted, as well as at least one output unit, for representation of the object D And the examination of the signals of picture elements.We are available for correlation of the first intensity values with the second intensity values. Preferably, the transmission and emission images are recorded simultaneously. The process also can be combined with other radiological images, for example, the tomography of positron emission tomography (PET) or by emission of photons only (SPECT).
