Transducers. 7. The couch
Transducers. One transducer will be used during this trial – a 7 MHz transducer with 3.0mm focal depth. The location to be treated, the transducer, and the energy level will be recorded on the Treatment Parameter System Record.
Transducers. The device that transforms electrical transmissions to ultrasound pulses and also ultrasound echoes into electrical signals is the transducer. This is composed of a piezoelectric element whose property is to expand or contract when a voltage is applied across it and also to generate voltages when stretched or compressed. The commonest material used in medical transducers is lead zirconate titanate (Xxxx 2009). Because the characteristic acoustic impedance of the piezoelectric element is 20 times higher than soft tissue a backing layer and a matching layer are required. The backing layer reduces the amount of ultrasound waves lost through reflection at the transducer/tissue interface whilst the impedance matching layer increases the amount of ultrasound waves transmitted at the transducer/tissue interface. The final element of the transducer is a lens which focuses the ultrasound beam. A variety of probes exist depending on the arrangement of transducers within them. The simplest arrangement is a linear array but other formats exist, such a curvilinear, trapezoidal or sector probes. Transvaginal probes are usually of the sector type.
