Compression of image data of a medical imaging device

A computer-implemented method for compression of image data of a medical imaging device, the image data including image points with image point values at defined positions, and the computer-implemented method comprising:

• stipulating at least one threshold value for the image point values for assignment of the image points to useful data and to background data on different sides of the at least one threshold value;
• creating a data header including information about the compression applied so that, based on the information of the data header, a reconstruction of the image data from compressed image data is possible;
• and
• reducing the image data to data points belonging to the useful data;
• storing the image point values of the useful data without the image point values of the background data;
• and
• storing location information that allows a location of the data points belonging to the useful data, together with respective image point values, to be reconstructed on at least one computer-readable storage medium.
