Abstract: A method for evaluating mechanical anisotropy of a material sample to determine a characteristic of the sample includes interrogating a material sample a plurality of times. Each interrogation includes: applying a force having a direction, having a coronal plane normal to the direction of the force, and having an oval or other profile with long and short axes within the coronal plane, the long axis being oriented at a specified angle from a reference direction within the coronal plane; and measuring displacement of the material sample resulting from application of the force. The interrogations are taken at different angles of orientation within the coronal plane and different portions of the material sample are interrogated. For each measurement one or more parameters are calculated for the respective angle of orientation. A degree of anisotropy of the one or more parameters is determined and used to evaluate a characteristic of the material sample.

Abstract: The embodiments herein provide a system for calibration-free cuff-less evaluation of blood pressure. The system includes an ultrasound-based arterial compliance probes and a controller unit connected to the said probe. The ultrasound transducers are configured to measure the change in arterial dimensions, pulse wave velocity, and other character traits of an arterial segment over continuous cardiac cycle, which is then used to evaluate blood pressure parameters without any calibration procedure using dedicated mathematical models. The pressure sensor/force sensor/bio-potential transducers/accelerometric sensors are configured to measure a pressure acting on a skin surface at a measurement site, an internal arterial transmural pressure level, an applied pressure or a hold-down pressure on the skin surface or an arterial site, biopotential and/or plethysmograph signal, arterial vibrations acting on the measurement site as a function of the arterial pressure and the mechanical characteristics and/or a function of the applied/hold-down pressure and/or function of external factors.

Abstract: A device for vibration controlled transient elastography, in particular to quantify liver fibrosis, includes an ultrasound probe for elastography comprising a probe casing, at least one ultrasound transducer having a symmetry axis, a vibrator, and a force sensor, wherein the vibrator is arranged to induce a movement of the probe casing along the symmetry axis of the ultrasound transducer, the ultrasound transducer being bound to the probe casing with no motion of the ultrasound transducer relative to the probe casing, and wherein the device includes a signal generator configured to issue a contact ready signal when the force applied by the probe on the to-be-measured viscoelastic medium is greater than a minimum contact force threshold. The signal generator may further be configured to issue a measurement ready signal when the force is greater than a minimum measurement force threshold.

Abstract: Methods for non-invasive fat reduction can include targeting a region of interest below a surface of skin, which contains fat and delivering ultrasound energy to the region of interest. The ultrasound energy generates a thermal lesion with said ultrasound energy on a fat cell. The lesion can create an opening in the surface of the fat cell, which allows the draining of a fluid out of the fat cell and through the opening. In addition, by applying ultrasound energy to fat cells to increase the temperature to between 43 degrees and 49 degrees, cell apoptosis can be realized, thereby resulting in reduction of fat.

In an embodiment, the assembly aims an acoustic signal in response to a sensed or detected force or load imposed on the MID. The directable acoustic transducer assembly includes a switch array and a plurality of directional acoustic transducer elements. The switch array responds to the force or load and activates the directional acoustic transducer elements closest to the source of the force or load. The switch array may include a plurality of switches, at least one of which responses to a force or load and may activate directional acoustic transducer elements having a target tissue in the field of view. The assembly includes embodiments that are responsive to various loads. A directable acoustic transducer assembly may be part of a diagnostic and/or therapeutic system, such as an RF ablation system.
