Abstract:
An ultrasonic probe comprising a source adapted to output ultrasonic energy, and an acoustic output sensor adapted to sense at least a portion of the ultrasonic energy. The ultrasonic probe may be, for example, part of an ultrasound system further comprising a controller, wherein the acoustic output sensor may be adapted to transmit a signal in response to sensed ultrasonic energy.
Abstract:
A method of modulating tissue of an internal organ in vivo is disclosed. The method comprises: fixating the tissue on a shaped device so as to shape the tissue generally according to a shape of the device; and focusing radiation on the fixated tissue using a radiation-emitting system so as to modulate the tissue, wherein the radiation-emitting system is non-local with respect to the shaped device.
Abstract:
Device, system and method of determining an acoustic contact between an ultrasonic transducer and a body subject to ultrasonic energy generated by the transducer. For example, a method of determining an acoustic contact between an ultrasonic transducer and a body subject to ultrasonic energy generated by the transducer may include determining an acoustic contact level between the transducer and the body based on at least one value of at least one parameter related to an electrical impedance at the transducer. Other embodiments are described and claimed.
Abstract:
Apparatus is provided for assessing a characteristic of a first acoustic field (22) at a first frequency in a region (24) of a medium (26), the first acoustic field generating oscillatory motion of scatterers (28) disposed within the medium, at the first frequency. An acoustic transducer (30) (a) generates a second acoustic field (32) at a second frequency in the region, the second frequency being higher than the first frequency, and (b) receives echo data of the second acoustic field scattering off the oscillating scatterers in the medium, the echo data containing Doppler-shifted frequencies related to the oscillations of the scatterers, resulting in a time-dependent Doppler shift that oscillates at a frequency that is related to the first frequency. Control circuitry (36) (a) extracts the oscillating time-dependent Doppler shift from the received echo data, and (b) converts the extracted Doppler shift into particle-velocity of the first acoustic field.
Abstract:
There is provided herein a system, method and an apparatus for delivering focused therapeutic energy, such as ultrasonic energy, the apparatus includes a transducer adapted to transmit focused energy to a target area tissue of a subject body and a positioning element adapted to shift the transducer while transmitting the focused energy to the target area tissue, wherein the positioning element is further adapted to substantially maintain a focal point of the transducer within the target area tissue of the subject body.
