ULTRA-SOUND COMPATIBLE ARTIFICIAL CRANIAL PROSTHESIS WITH CUSTOMIZED PLATFORMS
An intracranial prosthesis comprised of a relatively flat, ultrasound-compatible body capable of engaging a plurality of diagnostic instruments and/or intracranial delivery systems so that a practicing medical professional can monitor certain parameters of a patient or deliver therapeutic agents to the patient while using an ultrasound-monitoring device to image the patient's brain. The prosthesis is designed to allow for the continuous, uninterrupted, simultaneous monitoring of a number of parameters of a patient's brain at the patient's bedside.
Waveform visualization tool for facilitating medical diagnosis
A tool for facilitating medical diagnosis is disclosed herein, including an ultrasound device configured to collect ultrasound data from a patient, a display device, and a processing circuit configured to generate a cerebral blood flow velocity (CBFV) waveform based on the ultrasound data, determine morphology indicators identifying attributes of the CBFV waveform, and configure the display device to display the CBFV waveform and the morphology indicators.
PATIENT MONITORING
Disclosed is a patient monitor control unit (10) comprising a processor arrangement (11, 13) adapted to receive a series of ultrasound measurements received from a sensor (30) comprising at least one configurable ultrasound transducer; process said series of ultrasound measurements to obtain haemodynamic data of a patient coupled to the sensor; control a patient monitor (20) to display the obtained haemodynamic data; evaluate the obtained haemodynamic data to detect a variance in said data; and generate a reconfiguration signal for the at least one configurable ultrasound transducer, wherein the timing of said generation is a function of said evaluation. Also disclosed are a patient monitoring system, a method of operating a patient monitor control unit and a computer program product for implementing such a method.
Apparatus and method for determining blood flow velocity
Apparatus and method comprising an ultrasound transmitter, for placement at a first location on the body of a subject, to emit an ultrasound pulse; an ultrasound receiver, for placement at a second location on the body, to detect an emitted ultrasound pulse; and a controller in communication with the transmitter and receiver. The controller causes an ultrasound pulse to be emitted by the transmitter; receives a measurement signal from the receiver; determines, based on the received measurement signal, a time of arrival at the receiver, T.sub.1 s of a first part of the emitted ultrasound pulse; determines, based on the received measurement signal, a time of arrival at the receiver, T.sub.2, of a second part of the ultrasound pulse; and calculates, using T.sub.1 and T.sub.2, a flow velocity of blood in a blood vessel between the first location and the second location.
Non-invasive wearable heart valve monitor
The invention is a device, system, and method for monitoring function of heart valves. The invention includes a disposable patch having simple transducers and simple processing for monitoring heart valve performance via echo Doppler and processing the data to determine blood flow velocities and/or blood flow gradients.
SYSTEMS AND METHODS FOR LOCATING AND MONITORING A SUBCUTANEOUS TARGET SITE
Devices and methods are provided herein for locating and monitoring subcutaneous target sites. A device as described herein may comprise a base layer configured to attach to a portion of a subject's body in proximity to the target site; and a plurality of transducer elements on the base layer, wherein the plurality of transducer elements are configured to (1) transmit a set of signals that penetrate beneath the skin of the subject and (2) receive a set of reflected signals associated with underlying anatomical structures, the underlying anatomical structures comprising the target site and bodily tissue surrounding the target site, wherein the set of reflected signals is used to identify a location of the target site while the device is placed in situ on the subject's body, without having to physically move the device over the portion of the subject's body to search for the target site.
Method and system for enhanced ultrasound image acquisition using ultrasound patch probes with interchangeable brackets
A system includes an ultrasound patch probe and brackets having a body and a base. The body includes a coupler and a hollow interior portion. The coupler is operable to receive the probe at a pre-defined ultrasound acquisition angle. The coupler defines a probe opening to provide the probe access to the hollow interior portion of the body. The coupler of each of the brackets is arranged to receive the probe at a different pre-defined ultrasound acquisition angle. The base surrounds a perimeter of the body and defines a bracket opening that extends through the base to provide access to the hollow interior portion of the body. The base includes a bottom surface operable to be secured against skin of a patient. The ultrasound patch probe is communicatively coupled to an ultrasound imaging system and detachably coupleable to the coupler of any selected one of the brackets.
VITAL SIGN DETECTION AND MEASUREMENT
An example monitoring device for detecting and measuring a vital sign of a subject includes: a base; a battery mounted to the base; first and second transceivers attached to the base at opposing angles, and powered by the battery to transmit pulses and receive reflected pulses; an antenna powered by the battery, and configured to wirelessly transmit data acquired from the first and second transceivers; and a computing device powered by the battery, and operatively coupled to the first and second transceivers and the antenna, the computing device having a processing device and a memory storing instructions that, when executed by the processing device, cause the monitoring device to determine a respiration rate by detecting a cyclical change in distance based on the reflected pulses.
WIRELESS ULTRASOUND DEVICE AND RELATED APPARATUS AND METHODS
A system comprising an ultrasound device configured to communicate ultrasound data wirelessly to a remote computing device over a wireless communication link, wherein the ultrasound device and the remote computing device implement the wireless communication link using a set of functions to wirelessly transmit the ultrasound data.
METHODS AND APPARATUSES FOR ELEVATIONAL BEAMFORMING OF ULTRASOUND DATA
Aspects of the technology described herein relate to apparatuses and methods for performing elevational beamforming of ultrasound data. Elevational beamforming may be implemented by different types of control circuitry. Certain control circuitry may be configured to control memory such that ultrasound data from different elevational channels is summed with stored ultrasound data in the memory that was collected at different times. Certain control circuitry may be configured to control a decimator to decimate ultrasound data from different elevational channels with different phases. Certain control circuitry may be configured to control direct digital synthesis circuitry to add a different phase offset to complex signals generated by the DDS circuitry for multiplying with ultrasound data from different elevational channels.
