A method includes transmitting a focused ultrasound wave into a medium to form (i) an ultrasound intensity well within the medium that exhibits a first range of acoustic pressure and (ii) a surrounding region of the medium that surrounds the ultrasound intensity well and exhibits a second range of acoustic pressure that exceeds the first range of acoustic pressure. The method further includes confining an object within the ultrasound intensity well. Additionally, an acoustic lens is configured to be acoustically coupled to an acoustic transducer. The acoustic lens has a varying longitudinal thickness that increases proportionally with respect to increasing azimuth angle of the acoustic lens. Another acoustic lens is configured to be acoustically coupled to an acoustic transducer. The acoustic lens includes a plurality of segments. Each of the plurality of segments has a varying longitudinal thickness that increases proportionally with respect to increasing azimuth angle of the segment.

Systems for patient support, imaging, or transport include a modality with a support surface configured to support a patient thereon, a converter associated with the modality, the converter being configured to receive relatively low-volume high-pressure air from a source of the relatively low-volume high-pressure air and to convert the relatively low-volume high-pressure air into relatively high-volume low-pressure air, and an air flow device configured to receive the relatively high-volume low-pressure air from the converter and provide an air flow function to the modality using the relatively high-volume low-pressure air.

A catheter that fits within a blood vessel wall includes electrodes aligned along a longitudinal axis of the catheter that produce unfocused shock waves that propagate radially toward the blood vessel wall for treatment.

According to a high-intensity focused ultrasonic apparatus and a control method, an image of a region to be treated is obtained by means of an imaging device, a working assembly and a target coordinate point in the region to be treated are located by means of an optical tracking device, so that a positioning device can clamp the working assembly to quickly and accurately move to a working position corresponding to the target coordinate point, thereby enabling the working assembly to quickly and accurately release a high-intensity focused ultrasonic pulse to the target coordinate point, which improves not only the treatment accuracy but also the treatment efficiency of the high-intensity focused ultrasonic apparatus.

Aspects of stone identification methods and systems are described. According to one aspect, an exemplary method comprises: transmitting to a processing unit, with an imaging element mounted on a distal end of a scope, image data about a stone object inside a body cavity; generating from the image data, with the processing unit, a visual representation of the stone object and the body cavity; establishing from a user input, with the processing unit, a scale for the visual representation; determining from the visual representation, with the processing unit, a size of the stone object on the scale; comparing, with the processing unit, the size of the stone object with a predetermined maximum size to determine a removal status; and augmenting, with the processing unit, the visual representation to include an indicator responsive to the removal status. Associated systems are also described.

An intracorporeal pressure shock wave includes an expandable pressure shock wave reflector at the distal end of an intracorporeal catheter to direct shock waves from a shock wave generator within a human or animal blood vessel or body lumen.

A shock wave and/or ultrasound therapy system includes an ultra-sound and/or shockwave source suspended on a hexapod drive and an X-ray system. A system controller configured to generate control signals for the hexapod drive to align the ultrasound and/or shockwave source with the X-ray system based on the displacement of a known object between two images taken at different tilt angles of the X-ray system.
