Embodiment Construction

[0020] Referring now to the diagram, figure 1 A schematic depiction of an ultrasound probe of the present invention is shown in and illustrated generally at 10 . As stated above, the present invention seeks to provide an ultrasound probe 10 that is selectively operable across at least two different frequencies, thereby allowing an operator to perform ultrasound examinations across different ultrasound frequencies without having to change the probe. In this regard, in a preferred embodiment, the probe 10 of the present invention generally includes an acoustic transducer 12 having: a transmitting section 14 that generates and transmits an acoustic signal from a high frequency electrical signal; and a receiving region Section 16, which receives reflections of the transmitted acoustic signal and converts the received reflections into electrical signals. Furthermore, the probe 10 comprises a selection switch 18 which allows the user to selectively determine at which frequency the ...

Abstract

An ultrasonic Doppler probe (10) is provided for use in connection with non-invasive Doppler imaging of fluid flow within the human body. The Doppler probe (10) can be selectively operated at more than one frequency during the course of a Doppler imaging examination thereby enhancing the resolution of the image obtained while also increasing the effective depth of the image. The probe (10) of thepresent invention employs piezo-electric materials for the formation of acoustic transmitting (14) and receiving (16) transducers (12) that are positioned within the probe (10) to allow the probe (10) to be selectively operated at a number of different frequencies spanning no more than one octave in frequency range.

Description

technical field [0001] The present invention generally relates to an ultrasound probe for non-invasive measurement of fluid flow in the human body. More specifically, the present invention relates to an ultrasonic Doppler probe for measuring fluid flow in the human body that incorporates a dual-frequency acoustic transducer, thereby allowing the probe to operate at both higher and lower frequencies. operation without requiring the operator to change probes. Background technique [0002] As ultrasound technology has improved, non-invasive ultrasound diagnostic equipment has become an indispensable tool for clinical use. Real-time B-mode ultrasound imagers have been used for many years in conjunction with the exploration and imaging of fixed soft tissue structures in the human body. Additionally, more recent developments in Doppler ultrasound scanners have facilitated the non-invasive exploration of moving fluids in the human body. In fact, Doppler ultrasound has become the...
