The combined indentation and ARFI imaging system. A flat ended cylindrical tip is attached to a 250-gram Honeywell load cell to measure the load signal, which is then amplified by a Vishay 2310A strain gage conditioner. The XPS motion controller moves the translation stage and samples both the force signal and motor position synchronously, and then sends the data to the laptop computer to process and display. The custom transducer holder keeps the imaging plane and indenter tip aligned so that the indentation data can be registered and compared with the ARFI image data.
