ScanZyklus

ScanZyklus is a term used in German-language technical documentation to describe the repeating sequence that drives data acquisition in scanning systems. A typical ScanZyklus includes initiating the cycle, triggering or synchronizing with a source, integrating data for a defined dwell time, reading out and buffering the result, and preparing for the next cycle. Depending on the device, a cycle may start from an external trigger or an internal clock and may be synchronized with motion or another subsystem.

The ScanZyklus determines sampling density and speed. Key parameters include frame or line rate, dwell time, exposure, and the scan pattern (for example raster, circular, or spiral). The cycle duration affects image quality, motion sensitivity, and energy use. Some systems support multi-cycle acquisitions to improve signal-to-noise or to capture multiple modalities.

Applications span medical imaging (such as CT and MRI, which rely on repeated acquisition and readout), optical or laser scanning for 3D models, radar and LiDAR mapping, and industrial inspection. It can also appear in display technologies and high-speed cameras where sensors alternate between illumination, exposure, and readout.

Because definitions of a ScanZyklus vary by device and vendor, manuals describe it in terms of cycle time, trigger signals, and synchronization rather than a universal standard.
