Implant and system for predicting decompensation

Номер: US20120035453A1
Автор: Michael Lippert, Olaf Skerl
Принадлежит: Biotronik SE and Co KG

An implant predicts decompensation of a patient's heart based on an acoustic pressure measurement. The implant includes first and second acoustic transducers, which are matched to each other and which rest in/on the patient's thorax. The first acoustic transducer emits an acoustic signal which has at least one first signal portion having a first frequency. The second acoustic transducer is designed to receive and re-emit the emitted acoustic signal, or to reflect it, such that the first acoustic transducer receives the emitted acoustic signal. A signal processing unit communicates with at least one of the two acoustic transducers and determines an attenuation value as a function of the attenuation of the received acoustic signal versus the originally emitted acoustic signal, and provides a prediction signal as a function of a comparison of the attenuation value to a threshold value, wherein the prediction signal indicates the development of decompensation.

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.

Rotary ultrasound imaging system

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.

When transesophageal echocardiography is used to obtain a transgastric short axis view of the left ventricle of the heart, the best place to position the transducer is in the fundus of the stomach, aimed up through the left ventricle. The probes disclosed herein facilitate placement of the transducer in the optimum position within the fundus, despite wide variations in the distance between the lower esophageal sphincter and the fundus among different subjects. 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.

A mechanical scanning device is composed of an oscillating beam onto which a transducer is mounted, part of which is flexible such that the beam will oscillate at a frequency between 8 and 15 Hz when mechanically energized. To sustain oscillation, energy is supplied by means of two electromagnetic coils acting on two permanent magnets mounted on either side of the beam. In order to improve the linear performance of the probe, feedback control was employed. A position sensor along with supporting electronics was designed to provide control signal for the feedback system.
