Kirby, A. & Rowe, P. (2002) Ultrasound Measurement of Femoral Anteversion and Tibial Torsion, , , , , Final Report submitted to the Chief Scientist Office. Edinburgh: Scottish Executive.
This project aimed to establish a method of measuring femoral anteversion and tibial torsion using real time ultrasound images and a new system of electronic inclinometry. The inclinometry system was carefully calibrated and proved accurate to within 1 degree and precise to with 0.2 of a degree. Individual inclinometers were attached firmly to both a 5MHz and a 7.5MHz linear array ultrasonic transducer using a specially produced clamp which gripped the front and rear of the probe head. Two low profile flexible switches linked by wire to a data collection computer were used to start and stop recording of the output of the inclinometers at 50Hz
