Color representation of complex-valued ndt data

A system for establishing a presentation of data indicative of a non-destructive test (NDT) acquisition, the system comprising:

• a processor circuit;
• a memory circuit;
• and
• a communication circuit communicatively coupled with the processor circuit;
• wherein the memory circuit comprises instructions that, when executed by the processor circuit, cause the system to:
• receive acoustic echo data elicited by respective transmissions of acoustic pulses;
• transform the acoustic echo data to obtain a complex-valued representation of the acoustic echo data, the complex-valued representation comprising phase and amplitude data;
• apply a beamforming technique to the complex-valued representation to obtain magnitude values corresponding to respective pixel or voxel locations in an image, and to obtain data indicative of phase values corresponding to the respective pixel or voxel locations in the image;
• and
• assign color values to the respective pixel or voxel locations using the magnitude values and the phase values, the color values selected from a color space using a respective lightness parameter corresponding to a respective magnitude value and at least one respective hue parameter corresponding to a respective phase value.
