X-ray aperture control for computed tomography scanners | High-resolution X linear axis for drastically reduced X-ray dose - Laboratory / Analytics
Smallest dose with excellent image quality

This aperture control sets completely new standards in computed tomography by providing very high-resolution and low-noise images at an outstanding low radiation dose. When the X-ray source is rotated, the motion unit moves the X-ray apertures so that the X-ray beam can be adjusted to the minimum required radiation dose. In use, the assembly itself is moved continuously in a circular path around the patient. A particular challenge was the high acceleration transverse to the direction of movement caused by the rotation on a large diameter. This additional load requires a particularly stable assembly with minimal room for error.


Lowest stress on patients

• State-of-the-art and patient-friendly diagnostics, especially for newborns, children and overweight patients

• Minimal radiation exposure due to extremely fast imaging at a top speed of 50 mm/s for up to 80 % less radiation dose

• Extremely high-resolution, low-noise images with 70 - 80 % less noise due to repeatability up to 1.4 µm•

• Reduced noise level at high speeds

• High stability on large diameter despite high centrifugal force

• Enormous lifetime at over 3 million cycles
