Abstract: A soda-lime glass substrate formed through a heat-treatment method has an absorption coefficient ranging from about 0.15 ?,W/m·K to about 0.54 ?,W/m·K, and a free path length ranging from about 0.12 cm to about 0.24 cm. The heat-treated soda-lime glass substrate is formed by heating for a selected time at a pre-specified maximum temperature of about 270° C. to about 330° C. so as to remove thermally induced residual deformations from the substrate and then the substrate is slowly cooled so as to substantially avoid reintroducing thermally induced residual deformations into the cooling substrate. Thus, the soda-lime glass substrate is transformed to one at or close to its contraction saturation point. This allows the heat-treated soda-lime glass substrate to serve in a practical way as a substrate of a flat display panel.

An exemplary array embodiment includes a triple-row phased array with one array in the center row for imaging and two arrays in the outer rows for therapy. Different types of piezoelectric materials and stack configurations may be employed to maximize the respective therapy and imaging functionalities. Reflected therapeutic signals that would otherwise corrupt the quality of imaging signals received by the center-row array can be mitigated or removed by use of the coding and/or a notch filter when B-mode images are formed during therapy.
