The invention provides an ultrasound production source comprising a body containing an ultrasound transducer presenting in front an emission face, the body including an opening (5) defined by a tubular wall (6) and arranged so that the emission face of the ultrasound transducer faces towards the opening (5), the tubular wall (6) being provided externally with at least one thread (17) of a screw thread assembly system for co-operating with at least one complementary thread (16) either of a fastener ring (15) for fastening a flexible membrane (8) on the body, or of a protective cover, or of a ring fitted with an alignment system.

Devices, systems, and methods are disclosed for use in tomographic ultrasound imaging, large aperture ultrasound imaging and therapeutic ultrasound that provide for coupling acoustic signal transducers to body structures for transmitting and receiving acoustic signals. The acoustic signal transmission couplants can conform to the receiving medium (e.g., skin) of the subject such that there is an acoustic impedance matching between the receiving medium and the transducer. In one aspect, an acoustic coupling medium includes a hydrogel including polymerizable material that form a network structured to entrap an aqueous fluid inside the hydrogel. The hydrogel is structured to conform to the receiving body, and the acoustic coupling medium is operable to conduct acoustic signals between acoustic signal transducer elements and a receiving medium when the hydrogel is in contact with the receiving body such that there is an acoustic impedance matching between the receiving medium and the acoustic signal transducer elements.

Arrangements described herein relate to systems, apparatuses, and methods for managing gel on a subject to provide gel on a first area of the subject, including controlling a transducer to move to a second area of the subject and controlling the transducer to move the gel to the first area from the second area.

An acoustic gel pack includes a container, a first pad, and a second pad. The container is adapted to contain acoustic gel and includes a wall, a first end having a first opening, and a second end having a second opening. A chamber is defined within the wall between the first end and the second end. The first pad is removeably coupled to the container to seal the first opening. The second pad is removeably coupled to the container to seal the second opening. The seals formed by the first pad over the first opening and the second pad over the second opening are adapted to prevent fluid infiltration into the chamber.

The present disclosure relates to a chlorin derivative or a pharmaceutically acceptable salt thereof, a preparation method thereof, an anti-tumor composition including the chlorin derivative or the pharmaceutically acceptable salt thereof, use of the chlorin derivative or the pharmaceutically acceptable salt thereof in the treatment of a tumor, and a combination of the chlorin derivative or the pharmaceutically acceptable salt thereof and an ultrasound medical system. The chlorin derivative or the pharmaceutically acceptable salt thereof has a structure represented by formula (I), and the ultrasonic medical system comprises a transducer ultrasonic bed and a contact agent. The chlorin derivative of the present disclosure can be used in photodynamic therapy and sonodynamic therapy, thereby effectively inhibiting and treating cancer. ##STR00001##

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.

An ultrasonic apparatus (10) includes a support (2) for accommodating a portion of a patient (14). The support includes a first reservoir (8) with a transmission medium. The support further includes an ultrasonic wave source (9) having an emitting surface (7) being conceived to be oriented towards the portion of the patient (14) in use. The ultrasonic apparatus further includes a substantially transparent aperture (26) arranged in the support (2) for enabling an inspection of the first reservoir. A therapeutic system increases a workflow of the ultrasonic apparatus.

A shock wave device to provide treatment within a blood vessel includes a shock wave reflector that directs shock waves laterally to blood vessel walls in a direction perpendicular to a central axis of symmetry of a catheter.
