Product Information

X-ray dosimetry Incidental X-radiation ionises the air molecules in the plate capacitor. The ion dose and the ion dose rate can be calculated based on the ionisation current and on the irradiated air mass.

Radiography The length and position of an invisible metal object can be determined with the aid of two X-ray images that are taken perpendicularly with regard to each other.

Effects of contrast media A blood vessel model that is not visible from the outside is visualised on a fluoroscent screen with the aid of a liquid contrast medium and X-rays.

Absorption of X-rays The absorption of X-rays is determined as a function of the absorber thickness and material.

Computer Tomography An object is rotated vertically and subjected to X-rays. An X-ray sensor records the resulting X-ray images (direct, digital imaging). A software program calculates the sectional images and creates a 3-dimensional reconstruction.
