The system includes a memory that stores a trained model, and a processor. The processor acquires at least one treatment image including an image in which at least one energy device and at least one biological tissue are captured. The processor acquires information regarding an amount of energy supply, the information regarding an energy output setting of the energy device. The processor estimates, based on the treatment image, the information regarding the amount of energy supply, and the trained model, estimated remaining heat information regarding an amount of heat or a temperature of the energy device. The processor causes a notification section to make a notification based on the estimated remaining heat information.

The system includes a memory that stores a trained model, and a processor. The processor acquires a pre-treatment image in which at least one energy device and at least one biological tissue are imaged, and a state before application of energy is imaged. The processor estimates an estimated heat diffusion region from the pre-treatment image and information regarding an energy supply amount by processing based on a trained model stored in the memory. The processor superimposes the estimated heat diffusion region on a captured image of the camera and displays the captured image with the superimposed estimated heat diffusion region.

A two-dimensional wideband ultrasound transducer array for three or four-dimensional (volume+time) non-invasively imaging/mapping of electrical current in, for example, the brain through the skull, or the heart. The probe also has unique capabilities for three-dimensional transcranial or transthoracic pulse echo ultrasound (tissue structure, motion, bone thickness) and doppler blood flow imaging. The handheld device interfaces with an ultrasound delivery system for applications to human brain or heart imaging, ultrasound neuromodulation, and therapy. The handheld ultrasound array enables three-dimensional steering of an ultrasound beam through the human skull or chest for ultrasound, doppler, and acoustoelectric imaging and related modalities to aid in the diagnosis and treatment of brain or heart disorders.

Acoustoelectric imaging (AEI) offers a novel, non-invasive method for monitoring current densities produced by a deep brain stimulator (DB S) or other medical device. By providing visual feedback of the electrical current patterns produced by the device, AEI may help guide placement of an implant during surgery, monitor device performance during routine checkups and over time, and perform accurate calibrations (in vivo or in situ).

A food packaging system has a housing that includes a food receptacle. The food receptacle includes a food product that is available for purchase. A slot formed in the housing, and an induction heating element is positioned in the slot.

A method and system for simultaneously performing ultrasound and thermoacoustic imaging includes directing RF energy with an RF emitter through a surface of the RF emitter and toward a region of interest within the object, wherein the region of interest has a material, a reference, and a boundary between the material and the reference, wherein the RF energy thermoacoustically induces an ultrasound signal at the surface of the RF emitter that travels through the object and reflects at the boundary; using the thermoacoustic system to receive a thermoacoustic multi-polar signal from a specific location on the boundary, wherein the thermoacoustic multi-polar signal is induced by the RF energy; receiving the reflected ultrasound signal; utilizing the thermoacoustic system and the reflected ultrasound signal to map the specific location within the object; and utilizing the thermoacoustic system and the thermoacoustic multi-polar signal to determine a parameter at the specific location.

A method for identifying a material of interest comprises directing, using a radio frequency (RF) applicator, one or more RF energy pulses into a region of interest, the region of interest comprising the material of interest and at least one reference that are separated by at least one boundary; detecting, using an acoustic receiver, at least one multi-polar acoustic signal generated in the region of interest in response to the RF energy pulses; processing the at least one multi-polar acoustic signal to determine an electric field strength at the boundary; and identifying the material of interest based at least on the determined electric field strength.

A method and system for estimating fractional fat content of an object of interest. The method and system include a thermoacoustic imaging system comprising an adjustable radio frequency (RF) applicator configured to emit RF energy pulses into the region of interest and heat tissue therein and an acoustic receiver configured to receive bipolar acoustic signals generated in response to heating of tissue in the region of interest; and one or more processors. The one or more processors are able to process bipolar acoustic signals received by the acoustic receiver in response to RF energy pulses emitted into the region of interest using the RF applicator to determine a setting for the RF applicator that yields bipolar acoustic signals with at least one enhanced metric thereof, determine an impedance of the RF applicator used to yield acoustic bipolar signals with the enhanced at least one metric, and estimate fractional fat content of the object of interest using the determined impedance.

The present disclosure provides a system with an innovative electrode designed as an RF/microwave antenna as well as methods to monitor/assess biological tissue and perform surgical procedures.

Combined transducer arrays for imaging features of tissue include a transducer array configured for transmit-receive ultrasound imaging, and a transducer array configured for receive-only thermoacoustic imaging. The transmit-receive transducer array includes a plurality of transmit-receive array elements, and the receive-only transducer array includes a plurality of receive-only array elements. The receive-only array elements are registered with and surround the transmit-receive array elements. The receive-only transducer array and transmit-receive transducer array may be housed in an ultrasound probe. The combined transducer arrays may be used in composite imaging of tissue, based on the registration of the transmit-receive array elements and the receive-only array elements. Registration of the transmit-receive array and the receive-only array may involve physical alignment or proximity of these transducer arrays, and may use data representative of known geometry and positions of elements of the two arrays in reconstructing respective images (ultrasound and thermoacoustic) in composite imaging.
