Abstract

1,269,869. Ultrasonic transducers; ultrasonic lenses. F. HOFFMANN LA ROCHE & CO. A.G. 5 June, 1970 [5 June, 1969], No. 27181/70. Headings H4J and H4X. [Also in Division H1] An ultrasonic transducer assembly, e.g. for investigating human arterial wall motion using the Doppler effect, has an elongate preset curved printed circuit board 24 (Fig. 3) supporting ultrasonic transducer units 25 to 29 along its longitudinal axis. The preset curved board 24 permits securing of the assembly to an arm by an inflatable cuff without appreciably changing the curvature of the assembly. Piezo-electric elements 31, e.g. of lead zirconate titanate, are supported by individual fibreglass boards 32 on the curved board 24. Board 24 is of copper clad fibre-glass. A lens 30 (Fig. 2) is secured to each element 31. A flexible potting compound 33 leaves the lenses 30 exposed but helps to maintain the curved configuration. In use, a coupling paste fills the recesses 35 between adjacent transducer units 25 to 29. A cable 34 (Fig. 4) has shielded wires 36, 37 connected to board 24. A signal line 38 on the board 24 is connected to receiver units 25, 27, 29 and a signal line 39 is connected to transmitter units 26, 28. Earth lines 41 and 43 on each side of the board 24 are connected by a lead 42, 44 respectively. Alternatively, common transmitter and receiver units may be used in conjunction with a single signal line (not shown), its shield being connected to earth line 43. The lines 38, 39 are R.F. shielded by members (45, 46) Fig. 6 (not shown) of fibre-glass (47) clad with copper (48) and bonded to the board 24. The transducer assembly is secured by an inflatable cuff to a patient's arm. Lens.-The lenses 30 are insulators and have similar physical characteristics to those of the elements 31 to reduce the effects of external stress and strain including thermal expansion. A high ultrasonic velocity in the lens with respect to body tissue is required for maximum beam spread. The lenses are of ceramic or glass, preferably alumina. The lens may be convex across its width and flat or concave in the length direction. The lens may have a depressed face and concave and convex curvatures (Fig. 8). A rectangular cavity (56) Fig. 9 (not shown) houses the piezo-electric element 57. The element 57 may be secured to the circuit board 24 by silicone or epoxy insulation (58). An electric contact (61) from the element 57 passes through an aperture in the board 24 to connect with the rear of the board.
