Abstract: Methods, systems, and computer readable media for utilizing a therapeutic ultrasound device to perform mitral valve decalcification are disclosed. One method includes acquiring, via an ultrasound imaging component, imaging data of a mitral valve in real-time, defining a therapeutic region of interest corresponding to the mitral valve, and utilizing, by a system controller engine, imaging data from the ultrasound imaging component to determine an interval period of minimal mitral annular movement.

Abstract: In a feeder for dispensing moist feed pellets to fish in a fish farm, there are provided a feed storage hopper, a screen group for separating fish feed into edible-size pellets and feed waste, and a conveyor for conveying the feed material from the hopper to the screen group. The feed waste is collected in a receptacle for later recycling through a feed pellet extruder. The feeder also has an air delivery system comprising a venturi eductor and a nozzle for aspiring the edible-size pellets from the screen group and for delivering the pellets into an air stream directed toward a fish pen. Most importantly, the conveyor is a belt type conveyor with spaced-apart flights, providing this feeder with the ability to dispense discrete amounts of fish feed in an intermittent feed mode from the hopper, through the screen group and into the air delivery system.
