1. A handheld apparatus comprising:

  • at least one first transducer configured to generate first ultrasonic signals and receive reflected first ultrasonic signals;

    at least one second transducer configured to generate second ultrasonic signals;

    a diagnostic ultrasound system configured to control generation of the first ultrasonic signals and to perform image processing using the reflected first ultrasonic signals in order to generate real-time images of tissue in an animal, wherein the diagnostic ultrasound system comprises;

    a transmit/receive (T/R) switch coupled to a pulser, the at least one first transducer, and an analog front end, the pulser comprising a level shifter and coupled to the T/R switch, the analog front end comprising one or more filters, one or more amplifiers, and one or more analog-to-digital converters,a transmit (TX) beamformer comprising one or more registers and a clock engine and coupled to the pulser, anda processing device comprising a microprocessor, microcontroller, field programmable gate array (FPGA), digital signal processor (DSP), or application specific integrated circuit (ASIC) coupled to the TX beamformer, the analog front end, and a second processing device configured to perform image processing and generate the real-time images;

    a therapeutic ultrasound system configured to control generation of the second ultrasonic signals in order to ablate targeted tissue in the animal and sterilize the animal, wherein the therapeutic ultrasound system comprises;

    a function generator configured to generate a therapeutic signal,an amplifier configured to amplify the therapeutic signal,a directional circuit configured to provide a first portion of the therapeutic signal to an electrical impedance matching circuit and a second portion of the therapeutic signal to a power meter, the electrical impedance matching circuit configured to provide the first portion of the therapeutic signal to the at least one second transducer for the second ultrasonic signals, the power meter configured to measure a current power of the amplified therapeutic signal; and

    a portable housing that contains the at least one first transducer, the at least one second transducer, the therapeutic ultrasound system, and the diagnostic ultrasound system including the T/R switch, the pulser, the analog front end, the TX beamformer, and the processing device.
