  • the gantry is therefore simultaneously the holding and positioning device for the X-ray measuring system.
  • the X-ray measuring system records X-ray images from a variety of different directions.

  • three-dimensional views are generated on the display element.
  • anatomical details emerge particularly well, making them particularly well-suited for medical evaluation of anatomical features.
  • the CT represents anatomical structures in great detail. Its resolution lies in the submillimeter range. However, in a CT cross-sectional image, cancer cells do not look any different from healthy cells, so they are not recognized until so many have accumulated that they form an unusual structure.

  • the C-arm holding device for the X-ray measuring system allows almost unhindered access to a person on whom the intervention is to be carried out. A repeated check of the progress of the medical intervention is possible without any problems.
  • the person often has to be removed from the gantry by means of the patient bed at least a part.
  • Nuclear medical measurement methods which are used, for example, in tumor diagnostics, follow a different route of presentation.
  • a person to be examined is given a special functional contrast agent, a so-called radiopharmaceutical, which accumulates in certain body regions before the examination.
  • the radiopharmaceutical is a positron emitter, which releases a positron when decayed.
  • This is, for example, a glucose solution whose glucose molecules are labeled with fluorine atoms of the fluoroisotope 18 F.
  • the radioactively labeled Glucose molecules are incorporated, in particular, by body cells with increased metabolic activity. These regions of increased metabolic activity very often represent an accumulation of cancer cells.

  • the measured image information is converted into sectional images. In these sectional images, body regions with an increased metabolic activity can be detected.
  • SPECT single-photon emission tomography
  • a person to be examined is injected with a gamma emitter into the bloodstream, for example the metastable technetium isotope 99m Tc, which passes into the ground state with a half-life of 6.01 hours by emitting X-rays.
  • the atoms of the gamma emitter are distributed in the bloodstream of the person.
  • the emitted X-rays are detected in a spatially resolved manner by means of one or two scintillation detectors.

  • a hyperperfusion of a body region suggestive of a tumor.
  • a minor perfusion of a brain area indicates a brain dysfunction such as Alzheimer's disease or an epileptic disorder. It may also be an indication of a blood clot that, if left untreated, would lead to a stroke.
  • the sectional images measured by means of PET or SPECT therefore have a very important supportive function in diagnostics. Based on their image information can be the success be immediately understood.
  • PET or SPECT provide much less detailed anatomical information. Their spatial uncertainty is several millimeters. This is disadvantageous in particular when initiating therapeutic measures.
  • irradiation therapy with X-ray radiation in the case of an insufficiently accurate localization of a tumor, either healthy body tissue is destroyed during the irradiation or else a tumor is not completely irradiated.
  • healthy body tissue due to the local blurring of the measurement by means of PET or SPECT, also healthy body tissue must be removed in order to ensure a safe removal of the tumor.
