Two-dimensional Temperature Imaging Using Pulse-Echo Ultrasound

摘要

A review of the basic principles of 2D temperature estimation using pulse-echo ultrasound is given. Some of the limitations of this technique are addressed and new solutions are described. In particular, temperature imaging artifacts due to the thermoacoustic lens effects are described. A reconstructive imaging method employing a physics-based 2D filter and a projection method is presented. Results from phantom and tissue heating experiments employing different energy sources are shown.
