Embodiment Construction

[0016] figure 1 An integrated active ultrasound probe 100 is shown. In one embodiment, an integrated active ultrasound probe 100 includes an array 101 of ultrasound transducers 102 each connected to a transmitter and receiver circuit 112 . The transmitter portions of the transmitter and receiver circuits 112 each include a pulse generator 114 that transmits electrical pulses to the connected ultrasound transducers of the ultrasound transducer 102 . A pulse generator 114 generates electrical pulses that are coordinated by control circuitry 103 and buffered by transmitter delay circuitry 115 (including delays for controlling beam steering).

[0017] The receiver portion of the transmitter and receiver circuit 112 includes: an amplifier 116 ; and a receiver delay 117 for receiving ultrasound echoes detected by one of the connected ultrasound transducers 102 . In addition to controlling the transmitter signals to the ultrasound transducer 102, the control circuit 103 also uses t...

Abstract

An ultrasonic probe includes ultrasonic transducers and processing electronics to control emission of ultrasonic energy and to process and digitize returned echo data. Processed echo data can then be transmitted over a digital interface for display.

Description

technical field [0001] The subject matter disclosed herein relates to ultrasound probes, and more particularly to integrated active ultrasound probes connectable to multiple computing devices. Background technique [0002] Non-destructive testing devices can be used to inspect, measure or test objects to identify and analyze anomalies in the object. These devices allow an inspection technician to manipulate a probe at or near a surface of a test object in order to perform a test of the object's surface and its underlying structure. Non-destructive testing can be particularly useful in some industries such as aerospace, power generation, and oil and gas transmission or refining (eg, pipelines and welds). Inspection of the test object must be performed without removing the object from surrounding structures and at locations where anomalies that would otherwise not be identifiable by visual inspection may be located. Ultrasonic testing is an example of non-destructive testing...
