Strain Image Display Systems

A method of displaying strain image data for an imaged object, the method comprising:

• capturing strain image data defining deformation of said object over an imaged region of said object;
• determining local image quality data, said local image quality data comprising a measure of the quality of said strain image data varying over said imaged region;
• and
• displaying a representation of said strain image data for said imaged region of said object, using said local image quality data to provide a visual indication of the quality of said displayed representation varying over said imaged region or to improve a quality of said displayed representation of said strain image data.

A method of displaying strain image data for an imaged object, the method comprising:

• capturing strain image data defining deformation of said object over an imaged region of said object;
• processing said strain image data to determine local image quality data, said local image quality data comprising a measure of the quality of said strain image data varying over said imaged region;
• and
• displaying a representation of said strain image data for said imaged region of said object;
• wherein said capturing comprises capturing data for a plurality of image frames;
• and
• wherein said displaying comprises determining cumulative displacement or strain data for said imaged region of said object over a plurality of said image frames weighted by said local image quality data.

Apparatus for displaying strain image data for an imaged object, the apparatus including a processor coupled to data memory and to program memory, said program memory storing instructions for controlling the processor to:

• capture strain image data defining deformation of said object over an imaged region of said object;
• determine local image quality data, said local image quality data comprising a measure of the quality of said strain image data varying over said imaged region;
• and
• display a representation of said strain image data for said imaged region of said object, using said local image quality data to provide a visual indication of the quality of said displayed representation varying over said imaged region or to improve a quality of said displayed representation of said strain image data.
