Ultrasonic medical monitoring device and method
An ultrasonic medical monitoring device may include: at least one ultrasonic probe that scans a test subject to acquire an echo signal; a blood pressure measuring device that measures a blood pressure parameter of a peripheral artery of the test subject; a processor configured to receive the echo signal and process the echo signal to obtain a blood flow parameter, and to calculate a myocardial mechanic parameter that represents a synchronous coupling of a circulatory system of left ventricle-aorta-peripheral arteries circulation according to the blood flow parameter and the blood pressure parameter; and a display device that is coupled to the processor and displays the myocardial mechanic parameter.
MULTI-POSITION ULTRASOUND SYSTEM
A compression assembly is coupled to the gantry of an ultrasound breast imaging system. The compression assembly includes a pair of compression paddles mounted on a positioning track. Each compression paddle houses a transducer and has a compression material surface for patient contact. A motor moves the compression paddles along the positioning track to immobilize the breast for ultrasound imaging.
ACQUISITION WORKFLOW AND STATUS INDICATORS IN A HANDHELD MEDICAL SCANNING DEVICE
In an embodiment, a handheld ultrasound scanning device is disclosed. One embodiment of the handheld ultrasound scanning device comprises a housing configured for handheld use, an ultrasound assembly at least partially disposed within the housing and configured obtain ultrasound data, a display unit at least partially disposed within the housing and comprising a display, and a processor disposed within the housing, wherein the processor is in communication with the ultrasound assembly and the display unit. The processor operable to receive a selection of an anatomical structure to be scanned with the ultrasound assembly, receive ultrasound data from the ultrasound assembly, determine whether the received ultrasound data includes data representative of the anatomical structure, and output an indication to the display unit in response to the determining.
Systems and methods for detecting neurological conditions
Systems, apparatuses, methods, and non-transitory computer-readable media related to a tool for determining presence or absence of a neurological condition in a subject are provided. The tool includes an ultrasound device configured to collect ultrasound data from a head of the subject. The tool further includes a processing circuit configured to calculate a curvature metric based on the ultrasound data. The processing circuit is further configured to calculate a velocity asymmetry metric based on the ultrasound data. The tool is further configured to determine presence or absence of the neurological condition in the subject based on the curvature metric and the velocity asymmetry metric.
Method and apparatus to produce ultrasonic images using multiple apertures
A combination of an ultrasonic scanner and an omnidirectional receive transducer for producing a two-dimensional image from received echoes is described. Two-dimensional images with different noise components can be constructed from the echoes received by additional transducers. These can be combined to produce images with better signal to noise ratios and lateral resolution. Also disclosed is a method based on information content to compensate for the different delays for different paths through intervening tissue is described. The disclosed techniques have broad application in medical imaging but are ideally suited to multi-aperture cardiac imaging using two or more intercostal spaces. Since lateral resolution is determined primarily by the aperture defined by the end elements, it is not necessary to fill the entire aperture with equally spaced elements. Multiple slices using these methods can be combined to form three-dimensional images.
Biopsy and sonography method and apparatus for assessing bodily cavities
Apparatuses and methods for performing a procedure on a uterine cavity of a patient are disclosed. The methods can include visualizing the uterine cavity, biopsying a tissue with a biopsy device, and ejecting fluid from the biopsying device into the uterine cavity. The apparatuses can have a sealable acorn tip, a handle, a repositioning clip, a distal indicia, a proximal indicia, and a fluid reservoir. The biopsying device can be configured to biopsy and eject fluid under the control of a single hand of a user of the device.
Haptic feedback for ultrasound image acquisition
A system for providing navigational guidance to a sonographer acquiring images may provide haptic feedback to the sonographer. The haptic feedback may be provided through an ultrasonic probe or a separate device. Haptic feedback may include vibrations or other sensations provided to the sonographer. The system may analyze acquired images and determine the location of acquisition and compare it to a desired image based, at least in part, on the acquired image. The system may then provide the haptic feedback to guide the sonographer to move the ultrasonic probe to the location to acquire the desired image.
Patient interface system
A patient interface system for scanning a volume of tissue protruding from a patient, the system comprising: a base including a planar portion configured to support the patient in a prone configuration, and a frustoconical portion extending from the planar portion and defining a base aperture configured to receive the volume of tissue; and a support assembly configured to couple to the base, including a frame and a membrane retained in tension within the frame at a peripheral portion of the membrane, wherein the membrane defines a membrane aperture configured to align with the base aperture, and wherein the membrane is configured to deflect into the frustoconical portion of the base in response to the patient's weight. The system can further include an electrical subsystem including a pressure sensor array configured to generate signals in response to a pressure distribution resulting from the patient's weight at the patient interface system.
FETAL IMAGING SYSTEM AND METHOD
An ultrasound fetal imaging system uses an acceleration sensor (16) for generating an acceleration signal relating to movement of the ultrasound transducer (10). A user is guided in how or where to move the ultrasound transducer based on the results of image processing of the ultrasound images. The user can thus be guided to move the transducer in a certain direction so as to achieve a complete scan of a fetus in a shortest possible time. This limits exposure of the expectant mother to the ultrasound energy. The fetal image obtained may be used to determine a fetal weight, for example using regression analysis based on some of the parameters derived from the obtained image.
PERORAL ENDOSCOPIC APPARATUS
Disclosed is a peroral endoscopic apparatus of a swallowable type, the peroral endoscopic apparatus including: at least one imaging unit configured to perform imaging of a human body digestive system and output image data; at least one ultrasonic unit configured to output ultrasonic data on a submucosal region of the digestive system and a peripheral organ located therearound; a magnetic unit configured to adjust a position, a posture, and a proceeding direction of the peroral endoscopic apparatus in response to an external magnetic force; a transceiving unit configured to transmit the image data and the ultrasonic data to an external device or receive an external control signal; a control unit configured to control the imaging unit and the ultrasonic unit to perform imaging of the digestive system and the submucosal region simultaneously or individually; and a power supply unit configured to supply power.
