Disclosed is an ultrasonic diagnostic apparatus including: an ultrasonic probe that transmits and receives ultrasonic waves; an ultrasonic image generator that generates an ultrasonic image by using ultrasonic waves received by the ultrasonic probe; a simulated ultrasonic image generator that generates a simulated ultrasonic image simulating ultrasonic waves emitted from a different device different from the ultrasonic diagnostic apparatus by using ultrasonic waves received by the ultrasonic probe and based on different-device information on ultrasonic irradiation of the different device; an image combiner that combines the ultrasonic image generated by the ultrasonic image generator and the simulated ultrasonic image generated by the simulated ultrasonic image generator; and a hardware processor that outputs a composite image obtained by combining by the image combiner.

An ultrasound transducer assembly includes a housing; a wedge-shaped acoustic modal convertor (AMC) in the housing with a first surface exposed by an opening in the housing, and a second surface that meets the first surface at a tip located in the housing, and extends from the tip at an angle into the housing, wherein the second surface has a recessed portion formed therein, wherein the second surface of the AMC is oriented at a specific oblique angle to the first surface of the AMC; and a piezoelectric ultrasound transducer disposed in the recessed portion of the second surface of the AMC, wherein the piezoelectric ultrasound transducer is connected to an electrically tuned circuit that resonates at a specific frequency and has a finite bandwidth.

The present disclosure provides implants, sensor modules, networks, and methods configured to establish transcutaneous power and transcutaneous bidirectional data communication using ultrasound signals between two or more medical devices located on and within a body of a patient.

A medical device includes a treatment module configured to apply a treatment to a patient. The medical device includes an interface configured to operatively connect to a removable storage device storing authorization data that identifies a level of treatment authorization. The medical device includes a processing device configured to perform operations in response to receiving user input indicating a treatment should be initiated. The operations include determining whether the removable storage device is valid for use with the medical device. If the removable storage device is determined to be valid, the authorization data is accessed. The processing device determines whether the treatment is authorized based on the accessed authorization data. If the treatment is determined to be authorized, the treatment module is controlled to apply the treatment. If the treatment is determined to not be authorized, the treatment module is controlled such that the treatment is not applied.

Apparatuses and methods for electrohydraulic generation of shockwaves at a rate of between 10 Hz and 5 MHz, and/or that permit a user to view a region of a patient comprising target cells during application of generated shockwaves to the region. Methods of applying electro-hydraulically generated shockwaves to target tissues (e.g., for reducing the appearance of tattoos, treatment or reduction of certain conditions and/or maladies).
