Abstract: The invention relates to a transfer stack (TS) for transferring a portion of a foil within a perimeter (P) that includes a transducer (T) to an article (A) such as a medical device or a medical needle. The transfer stack includes a carrier substrate (CS), a foil (F) having a transducer (T) incorporated therein, and the transducer is laterally surrounded by a perimeter (P). The foil (F) is separable from the carrier substrate (CS) by overcoming a first peel retaining force (PRF1). An adhesive layer (AL) is also attached to the foil. The adhesive layer (AL) is configured to provide adhesion between the foil (F) and an article (A) such that when the article (A) is attached to the foil via the adhesive layer (AL) the foil (F) is separable from the surface of the article (A) by overcoming a second peel retaining force (PRF2). The second peel retaining force (PRF2) is greater than the first peel retaining force (PRF1).

Abstract: Rotational intravascular ultrasound (IVUS) imaging devices, systems, and methods are provided. Some embodiments are directed to transducer mounting configurations that enable polymer piezoelectric micro-machined ultrasonic transducers (PMUTs) to be used with a Doppler color flow rotational IVUS imaging system. In one embodiment, a rotational intravascular ultrasound (IVUS) device includes: a flexible elongate body; a piezoelectric micromachined ultrasound transducer (PMUT) coupled to a distal portion of the flexible elongate body; and an application-specific integrated circuit (ASIC) coupled to the distal portion of the flexible elongate body. The ASIC is electrically coupled to the PMUT and includes a pulser, an amplifier, a protection circuit, and timing and control circuitry for coordinating operation of the pulser, amplifier, and protection circuit. The PMUT transducer is mounted with a tilt angle such that the IVUS catheter can be used to collect Doppler ultrasound blood flow data in conjunction with the IVUS imaging.

Abstract: A switched resonant power amplifier system for ultrasonic transducers is disclosed. The system includes an amplifier that receives and processes a driver output signal for generating a drive signal that is provided to an ultrasonic device for controlling output of the ultrasonic device. An output control circuit receives and processes a signal related to a feedback signal generated by the ultrasonic device and a divider reference signal, and generates a compensated clock signal that is adjusted for at least one of phase and frequency differences between the received feedback signal and the divider reference signal. A compensated drive circuit receives and processes the compensated clock signal for generating the divider reference signal, and for generating the driver output signal.

Abstract: Disclosed is an ultrasound diagnostic imaging apparatus including an ultrasound probe which outputs transmission ultrasound toward a subject due to a pulse signal being input and which outputs a received signal by receiving reflected ultrasound from the subject and a transmission unit which makes the ultrasound probe generate the transmission ultrasound by outputting a pulse signal whose drive waveform is formed of rectangular waves. The transmission unit outputs pulse signals whose drive waveforms are asymmetric to each other on a same scanning line for a plurality of times with a time interval therebetween. The ultrasound diagnostic imaging apparatus further includes an image generation unit which combines received signals each of which obtained from the reflected ultrasound of the transmission ultrasound generated by each output of pulse signal and generates ultrasound image data on a basis of a composite received signal.
