HIGH RESOLUTION FREEHAND 3D ULTRASOUND
G.M. Treece, A.H. Gee, R.W. Prager, C.J.C. Cash and L.H. Berman
This paper describes a high resolution freehand 3D ultrasound system, whose accuracy surpasses that of previously documented systems. Such accuracy is achieved through a series of novel system design and calibration techniques. The accuracy is quantified using a purpose-built, tissue-mimicking phantom, designed to create idealised in vivo scanning conditions. The paper includes a thorough discussion of the various different ways of measuring system accuracy and their relative merits, and compares in this context all recently documented freehand 3D ultrasound systems.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
