Conformal bone system. A transducer dedicated to bone applications was developed and is currently European Conformity (CE) approved. (a) This is a mobile multielement (1000-elements, 0.55-MHz) transducer with electronic steering which can be directly applied to the skin surface to be used as acoustic window to access the bone lesion and to improve the comfort of the patient. In (b) the transducer is applied for the treatment of a metastasis to the humerus from prostate cancer, with the patient lying supine; T2 weighted images with fat saturation show a slight oedema of the surrounding soft tissue after treatment.
