TL;DR: In this paper, an ultrasonic diagnosis and treatment system with a thin tube which is capable of being inserted into a body cavity, and which has at its extreme end an observing ultrasonic vibrator for emitting ultrasonic wave for observation and a treating ultrasonic vibration for emitting strong ultrasonic waves for treatment is described.
Abstract: An ultrasonic diagnosis and treatment system having a thin tube which is capable of being inserted into a body cavity, and which has at its extreme end an observing ultrasonic vibrator for emitting ultrasonic waves for observation and a treating ultrasonic vibrator for emitting strong ultrasonic waves for treatment. Observation and treatment are performed by using ultrasonic wave. The system further includes a processing device for performing an operation other than the ultrasonic treatment at least on a region observed by using ultrasonic waves. A guide for enabling the processing device to reach the region observed by using ultrasonic waves is provided on the thin tube.

TL;DR: In this article, a prototype system with full computer support for ultrasonic inspection of ferritic tubes using guided waves is described, where ultrasonic waves are launched and received with the aid of electromagnetic acoustic transducers which are layed out as linear phased arrays.

TL;DR: The number of entry zones required for complete coverage of the outer surface of a tube or pipe is a function of the size of the tube, the speed at which it passes through the inspection station and the rate of rotation as discussed by the authors.
Abstract: One or more phased array ultrasonic probes in the shape of conical section arcs, or an entire conical section ring, emit beams at a fixed incident angle with respect to the outer surface of a tube or pipe under inspection. At any given moment, these beams strike the tube at a single small entry zone from number of different directions. After being refracted at the inspection angle corresponding to the fixed angle of incidence, defects having longitudinal, transverse and oblique orientations are detected in the three-dimensional volume of the tube wall. The number of entry zones required for complete coverage of the outer surface of the tube is a function of the size of the tube, the speed at which it passes through the inspection station and the rate of rotation of the tube.

TL;DR: An ultrasonic inspection probe for locating and sizing flaws in the radius region (20) and adjacent areas of a laminated structure (10), such as a composite "T" stiffener (30).
Abstract: An ultrasonic inspection probe for locating and sizing flaws in the radius region (20) and adjacent areas of a laminated structure (10), such as a composite "T" stiffener (30). The probe includes a plurality of shoes (48, 50, 52, 54, 56, 58) that are arranged for coordinated movement relative to the part under inspection. Each shoe includes a plurality of ultrasonic transducers that are arranged in predetermined adjacent relationships to one another and operated in timed sequence in one or more through-transmission, pulse echo or loss-of-back modes to effect an ultrasonic scan in one direction through the part while the transducers are moved together in another direction along the part. Inspection of the radius region is effected using combinations of angular pulse echo inspection (PEF, PEA, LL45P, RL45P), "radius-to-radius" through-transmission inspection at an angle through the radius region (RTT, RTR, L37.5T, L37.5R, U37.5T, U37.5R), and "flange-to-radius" through-transmission inspection normally into the upper flange (RU45T) and angularly out through the radius RU45R, LU45R).

TL;DR: In this paper, Magnetic coupling is used for supporting a pair of leader-follower probes and defining offset positions between angle beam shear wave transducers carried by the probes, which can be collected for supporting real-time generation of three-dimensional image representations of the structure and of internal defects and features.
Abstract: Improved methods, systems, and apparatus for inspecting a structure using angle beam shear wave through-transmission ultrasonic signals involves positioning transducers at offset positions on opposing sides of the structure and permits inspection of the inside of the structure beneath surface defects and features. Magnetic coupling can be used for supporting a pair of leader-follower probes and defining offset positions between angle beam shear wave transducers carried by the probes. Inspection data can be collected for supporting real-time generation of three-dimensional image representations of the structure and of internal defects and features of the structure. Image generation and resolution using inspection data from angle beam shear wave ultrasonic signals can be supplemented using pulse-echo ultrasonic inspection data.
