KLONK Image Measurement was initiated while Christian Andersen, was studying IT in 1993. During a research project within healthcare, it came to his attention that tools for tracing and measuring sizes within medical research needed to be improved. The first product developed was a small software tool designed for determining the size of areas where the individuals felt pain. This was the first version of KLONK Image Measurement.

A more commercial version was developed later with a technology including tracing on paper sheets on a digitizer, this version of the software was called Quantify One. Later a new version based on measuring on scanned or imported images was created and the software was renamed to Quantify Image. Now the tool is called Image Measurement.
