Pressure control in medical diagnostic ultrasound imaging

Номер: US20120083692A1

Автор: Jeffrey Stoll

Принадлежит: Siemens Medical Solutions USA Inc

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.

Rotary ultrasound imaging system

Номер: US20120123272A1

Автор: Helen L.W. Chan, Ji Yan Dai, Kwok Ho Lam, Yan Chen

Принадлежит: Hong Kong Polytechnic University HKPU

This invention relates to a rotary ultrasound imaging system comprising a control device, an ultrasound probe head and a rotary motor device, wherein the rotary motor device receives ultrasound signals sent from the ultrasound probe head, and outputs the received ultrasound signals to the control device through a 360-degree rotation; and the ultrasound probe head comprises a housing with an installation groove which is provided therein with an ultrasound transducer with a concave focusing surface. Since the concave focusing surface is directly formed on the ultrasound transducer, focusing of the rotary ultrasound imaging system is realized without addition of extra components (e.g. lens). Therefore lateral resolution and performance are improved. Furthermore, since the output shaft of the rotary motor of the rotary ultrasound imaging system is configured as a hollow shaft, ultrasound signals from the ultrasound transducer may be sent to the control device through a path of 360-degree rotation. Therefore, complicated modules are not necessary for position alignment and signal connection for 360 degrees rotary ultrasound transducer. The invention may efficiently shield disturbances arising from electrical noise.

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.

In one preferred embodiment, the ultrasound probe uses a bending section with a series of vertebrae and stiffening that is more flexible proximally and less flexible distally, which causes the probe to bend relatively sharply at the point where the probe exits the lower esophageal sphincter. The flexibility of the proximal-most portion of the bending section is preferably greater than or equal to the flexibility of the interface between the bending section and the shaft.

Methods and devices are disclosed that, in various embodiments and permutations and combinations of inventions, diagnose and treat Multiple Sclerosis, Deep Vein Thrombosis, and/or Pulmonary Embolism or symptoms associated with these maladies. In one series of embodiments, the invention consists of methods and devices for identifying patients whose Multiple Sclerosis, Deep Vein Thrombosis, and/or Pulmonary Embolism or associated symptoms are caused or exacerbated, at least in part, by blockages of one or more of the patient's veins. In some instances, stenoses or other flow limiting structures or lesions in the patient's affected veins are identified. Further, in some instances the nature of such lesions and whether there is a significant disruption of blood pressure, or both, is ascertained. In some embodiments, methods and devices for applying one or more therapies to the blockages in the patient's veins are provided.

Methods and systems are described that reduce risks of hematologic, metabolic, and renal complications in a mammal, such as a human, undergoing tissue ablation. One such method includes inserting a probe into a mammal and ablating abnormal tissue in the mammal by emitting a first amount of energy from the probe. In some embodiments, after emitting the first amount of energy, a method can include denaturing proteins released from cells in the abnormal tissue by emitting a second amount of energy from at least one of the first probe or a second probe inserted into the mammal. Furthermore, some embodiments can be implemented such that during or after the emitting the energy from a probe, a composition is administered to the mammal in an effective amount to denature proteins released from cells in the abnormal tissue.

A method for assessing a liver includes acquiring image information including contrast-enhanced ultrasound images of the liver. A location of the main hepatic artery (MHA) and a location of the main portal vein (MPV) of the liver are identified in at least one of the contrast-enhanced ultrasound images of the liver. Time-intensity information corresponding to perfusion of a contrast agent in the MHA and the MPV is obtained. A biomarker index value (BW) which is a function of the time-intensity information corresponding to the perfusion of contrast agent in the MHA and the time-intensity information corresponding to the perfusion of contrast agent in the MPV is determined.

Usage patterns known to increase risk of injury can also be used to identify poor scanning techniques during a scan and provide in-scan feedback to an ultrasound user to change scanning behavior. Data regarding scan technique can be aggregated to determine the risk of injury to an individual ultrasound machine operator. This data may be used by ultrasound machine operators and ultrasound managers to prevent injury by pre-emptively correcting scan technique associated with injury.

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.
