The array-type scanning acoustic tomograph includes a selection unit to select the elements constituting a vibrator group that connects vibrator drive signals and reception signals. The vibrator group is divided into a first group that emits ultrasonic beams to a former half of an ultrasonic beam irradiation region and a second group that emits ultrasonic beams to a latter half of the ultrasonic beam irradiation region. The selection unit is instructed to select the vibrator groups of the first group to emit ultrasonic beams, instructed to select the vibrator group of the second group to emit ultrasonic beams, then the selection unit is instructed to select the vibrator groups of the first group to receive reflected ultrasonic waves, and then instructed to select the vibrator group of the second group to receive reflected ultrasonic wave, and the same waveforms are displayed on a display unit without overlapping.

Described are transducer assemblies and imaging devices comprising: a microelectromechanical systems (MEMS) die including a plurality of piezoelectric elements; a complementary metal-oxide-semiconductor (CMOS) die electrically coupled to the MEMS die by a first plurality of bumps and including at least one circuit for controlling the plurality of piezoelectric elements; and a package secured to the CMOS die by an adhesive layer and electrically connected to the CMOS die.

A system may include an ultrasound probe and a controller unit configured to communicate with the ultrasound probe. The controller unit may be further configured to select an aiming mode for the ultrasound probe; select a first aiming mode plane, scanning mode, or imaging mode; select at least one additional aiming mode plane, scanning mode, or imaging mode; toggle between obtaining and displaying ultrasound images associated with the first aiming mode plane, scanning mode, or imaging mode and obtaining and displaying ultrasound images associated with the at least one additional aiming mode plane, scanning mode, or imaging mode; receive a selection of a three-dimensional (3D) scan mode; and perform a 3D scan using the ultrasound probe, in response to receiving the selection of the 3D scan mode.

The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections. The GUI is capable of displaying the 3-D image as each additional 2-D cross section is scanned by an ultrasonic testing apparatus in real time or near real time, including probable defect regions that contain a flaw such as a hole, crack, wrinkle, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting defect areas within the 3-D image in real time or near real time and providing data regarding each defect area, such as the depth, size, and/or type of each defect.

A wading staff is provided herein that is configured to provide stability for an angler that is standing in a body of water. The wading staff includes a staff portion defining a first end and a second end, a handle disposed proximate the first end of the staff portion, and a sonar transducer disposed at least partially within the staff portion. The sonar transducer is configured to transmit a sonar beam into an underwater environment. The sonar transducer is positioned and oriented within the staff portion such that the sonar transducer is configured to transmit the sonar beam into a portion of the underwater environment when the staff is at least partially submerged. A display may be mounted to the wading staff or located remotely to display corresponding sonar images.

An echogenicity quantitative test system for a sample echogenic medical device includes a fixture into which the echogenic medical device is positioned in relation to an ultrasonic probe connected with an ultrasound diagnostic device. The fixture includes a frame; a probe holder having a first guide rod and a probe clamp configured to hold the ultrasonic probe and movably held on the first guide rod, and a sample holder having a second guide rod and a sample clamp configured to hold the medical device sample. The sample clamp is movably held on the second guide rod. The frame may include guide rails, and the first guide rod and the second guide rod are movably disposed in the guide rails so as to allow for adjustments to the relative positions of the ultrasonic probe and the sample echogenic medical device.
