Computer tomography (CT)

One of the highlights is our dual-source-dual-energy-CT with 320 lines that is equipped with two X-ray tubes. The result: multiple times higher scanning speed, higher image quality, better display, most precise diagnostics despite up to 90 percent lower radiation dose. This is particularly advantageous when examining the coronary arteries. (The entire heart can be scanned in less than a second)

The X-rays are measured with detectors as they pass through the body and then converted into cross-sectional images using a computer (scanning speeds from 2 to 350 milliseconds with simultaneous acquisition of up to 384 slices). The necessary radiation dose can be reduced by up to 90 percent using the latest technology.

The result: precise and overlay-free images that enable precise evaluation and analysis; The smallest differences in density - and thus the finest structures, such as in the lungs or in the abdomen - can be displayed.

Special measuring programs enable the representation of the dental apparatus or the determination of the bone mineral salt content in osteoporosis examinations.

Common uses

  • Diagnosing changes in the brain
  • Examination of diseases of the spine (e.g. intervertebral discs)
  • Diagnosis of diseases of the facial skull (e.g. paranasal sinuses) and the neck (e.g. larynx or lymph nodes)
  • Method for examining the fine structure of the lungs, bones and the middle- and inner ear
  • Assessment of diseases of the chest and lungs
  • Examination of diseases of the abdominal organs (liver, pancreas, spleen, kidney and adrenal gland)
  • Special examinations of the small and large intestines for therapy-resistant and unexplained abdominal pain and for chronic inflammatory bowel diseases
  • Ideal method for visualizing lymph nodes
  • Diagnosis of diseases of the pelvic organs (e.g. ovaries) and the pelvic soft tissues
  • Safe method of visualizing the large vessels (e.g. aorta or pulmonary arteries)
  • Dental CT: three-dimensional representation of the upper and lower jaw and the teeth (e.g. before dental implants)
  • Osteoporosis CT: reliable and informative method for determining bone density
  • Cardio-CT: reliable, non-invasive method for determining the calcium content of the coronary arteries and for the exclusion or detection of a significant coronary heart disease
  • Virtual colonoscopy: four-dimensional representation of the large intestine and rectum. Detection or exclusion of polyps and tumors (as an alternative to conventional endoscopy)
  • Low-dose multi-slice spiral CT of the lungs: early detection of bronchial carcinoma (radiation exposure corresponds to one chest X-ray)


What is a CT scan?

Computed tomography (CT) is a special x-ray examination that is used to make cross-sectional images of the body. This enables important information to be obtained about the location of the foci of disease. This is often of crucial importance for further treatment.

When is a CT scan performed?

The main reason for a CT scan is that it is impossible to make a diagnosis without knowing what the inside of the body is like. In order to enable an exact diagnosis it is usually necessary to have a series of images of the internal structures of the body.

How does a CT examination work?

The examination takes a few minutes. During the examination you lie on a special examination table that moves through the opening of the CT device. During the entire examination, you are under the supervision of qualified personnel and connected to them via an intercom. In order to achieve the best possible quality of the images, we ask you to remain still during the entire examination. For some examinations we may ask you to follow instructions (e.g. inhale, exhale, hold your breath, do not swallow, etc.).

Our contribution to more security?

With more than 30,000 systems installed, Canon computer tomographs are valued by professionals worldwide for their excellent image quality, usability and reliability. Fast and safe imaging for patients is the focus of all our developments. Canon Medical's developments enable radiation dose reductions of up to 82%. Other technologies such as dynamic volume-computed tomography enables recordings of entire organs such as of the heart or brain in less than 1 second, increasing your safety and comfort.
