Contact pressure from a transducer is controlled in medical diagnostic ultrasound imaging. Rather than measuring pressure directly using a pressure sensor on the transducer, the compression of tissue within the patient may be measured using ultrasound scanning. The desired amount of compression in the region of interest for diagnosis may be obtained. For example in breast imaging, the desired compression for imaging a portion of the breast is compared to compression measured from ultrasound data. Once the desired tissue compression is achieved, the pressure applied by the transducer is maintained while the diagnosis scan occurs. For example, a robotic arm locks or otherwise maintains the pressure during scanning.

Techniques exist for measuring local blood velocity of flow rate waveforms in, for example, mammalian vascular segments. A method and system for deriving information on disease in vascular segments, for example mean pressure, drop in mean pressure and/or hydraulic resistance, from such measured waveforms is described. The waveforms can, for example, be measured non-invasively using Doppler ultrasound or magnetic resonance techniques. Form factors (Vff, Pff) for the velocity waveform and the centreal arterial pressure are determined. Stenosis may be detected by detecting changes e.g in Vff/Pff.

The present disclosure provides a precise performance three-dimensional ultrasound scanner that is lightweight for an easy hold by suggesting a novel constitution of a swing mechanism wherein an arrangement of the drive motor perpendicular to the swing axis requires a smaller capacity motor and eliminating a backlash. The swing mechanism includes: an arm holder connected to a rotational axis of the motor; an arm connected to the arm holder so that the arm swings within a certain angular range; a link, attached to the arm, for moving in unison with the arm; a shaft, connected to the link, for transmitting a rotary power of the arm to the transducer unit. The swing mechanism can be operated using the smaller capacity motor and eliminates the need for a pulley, gear or belt eliminating backlashes to promote implementation of lightweight precision three-dimensional ultrasound scanners.

Acquired echo data is corrected to reduce content from ultrasound that has undergone at least one reflection off the probe surface, for example, to reduce corresponding reverberation artefacts from imaging. In some embodiments, the propagation medium, i.e., layer or adjoining layers, through which the reverberation occurs, is, after a set of echo radiofrequency data ( 404, 408 ) has been acquired, modified in preparation for a next application of ultrasound. During that next application, it is the reverberating ultrasound signals ( 424 ), according to embodiments of the invention, that are more affected by the modification than are the non-reverberating, i.e., direct signals ( 420 ). This difference in effect is due, for example, to greater overall time of flight through the modified medium on account of reverberation in the propagation path.

The Energy Field and Target Correlation System automatically correlates the characteristics of target particles and a living organism to compute the characteristics of an energy field that is applied to a living organism to activate the target particles which are bound to or consumed or taken up by invasive agents in the living organism to produce detectable effects which can be used to diagnose the presence and locus of the invasive agents. The energy field must be crafted to properly control the response and localize the extent of the illumination. The System automatically selects a set of energy field characteristics, including: field type, frequency, field strength, duration, field modulation, repetition frequency, beam size, and focal point. The determined energy field characteristics then are used to activate field generators to generate the desired energy field. A multi-dimensional image is produced identifying the spatial extent of the invasive agent.

An apparatus for securing a marker wire relative to a lumen includes a hub to which the marker wire is secured. The hub includes a feature that secures the hub to an outer surface of the lumen. For example, the hub may include a base member secured to the marker wire and a separate fastener member which secures the hub to an outer surface of a lumen, where the base member includes a split tube segment that receives the lumen within an inner cylindrical opening. Alternatively, the hub may include a cylindrical slide lock collar member with a split tubular extension that receives the lumen within an inner cylindrical opening. Locking features may be included to help fix the two pieces of the hub in position relative to each other.

A device (e.g., a valve) can be visualized in a patient's body (e.g., in the patient's heart) using an ultrasound system with added position sensors. One position sensor is mounted in the ultrasound probe, and another position sensor is mounted in the device installation apparatus. The device's position with respect to the imaging plane is determined based on the detected positions of the position sensors and known geometric relationships. A representation of the device and the imaging plane, as viewed from a first perspective, is displayed. The perspective is varied to a second perspective, and a representation of the device and the imaging plane, as viewed from the second perspective, is displayed. Displaying the device and the imaging plane from different perspectives helps the user visualize where the device is with respect to the relevant anatomy.

Image guided high intensity focused ultrasound treatment of nerves

Номер: US20120316426A1
Автор: James W. Little, Jessica L. Foley, Shahram Vaezy
Принадлежит: UNIVERSITY OF WASHINGTON

A method for using high intensity focused ultrasound (HIFU) to treat neurological structures to achieve a desired therapeutic effect. Depending on the dosage of HIFU applied, it can have a reversible or irreversible effect on neural structures. For example, a relatively high dose of HIFU can be used to permanently block nerve function, to provide a non-invasive alternative to severing a nerve to treat severe spasticity. Relatively lower doses of HIFU can be used to reversibly block nerve function, to alleviate pain, to achieve an anesthetic effect, or to achieve a cosmetic effect. Where sensory nerves are not necessary for voluntary function, but are involved in pain associated with tumors or bone cancer, HIFU can be used to non-invasively destroy such sensory nerves to alleviate pain without drugs. Preferably, ultrasound imaging synchronized to the HIFU therapy is used to provide real-time ultrasound image guided HIFU therapy of neural structures.
