A method of fetal ultrasound monitoring includes detecting contact of a first ultrasound transducer to a mother’s abdomen based on input from a contact sensor in the first ultrasound transducer. A first transducer identifier is received from the first ultrasound transducer, and then the first transducer identifier is correlated with a first transducer label. A first heart rate is measured based on output of an ultrasound device in the first ultrasound transducer, and a heart rate indicator is displayed accordingly. A position of the first ultrasound transducer is identified in a two-dimensional plane, and the first transducer label is displayed on an abdomen image based on the first position.

The present invention relates to an improved fetal heart rate transducer that overcomes shortcomings of prior transducers in several ways including utilizing an ultra slow-cure epoxy in combination with a piezo-electric disc bonding method to improve ultrasound transmission and reception characteristics, utilizing a slow-cure epoxy in combination with a frontend PCB bonding method to improve transducer reliability, utilizing a metal insert design in combination with molding-in techniques versus press fitting to improve the mechanical stability of the transducer, and utilizing a failsafe LVDS circuit to improve cable error detection and thus improve fetal monitor system reliability. In addition, a method of use of the present invention includes quantitively determining the integrity of each of the piezo-electric disc bonds with the plastic substrate as well as the integrity of the ultrasound field using various height water phantoms that simulate the human body.

A computer-implemented method of automatically identifying a reference vessel in an ultrasound image, the method comprising: segmenting the image to identify an organ; locating a predetermined anatomical landmark specific to the organ; identifying appropriate vasculature for the organ; and selecting a reference vessel from the vasculature that has a size within a predetermined size range and a location with a predetermined distance range from the predetermined interface.

An ultrasonic endocavitary imaging system for developing an image of a portion of a body cavity includes an elongate probe having a longitudinal axis, a distal end configured for insertion into the body cavity, a proximal end opposite to the distal end. The system also includes a shaft rotatably mounted in the probe, in a manner supporting rotation about the longitudinal axis, and having a proximal end protruding from the proximal end of the probe and a distal end opposite to the proximal end. The system further includes handle pivotally attached to the proximal end of the shaft and configured to rotate the shaft within the probe and an image capture assembly. The image capture assembly includes a piezo crystal array, the array coupled to the distal end of the shaft and having an axis aligned with the longitudinal axis, the array configured to cause capture of an ultrasound image of the interior of the body cavity lying in a plane through which the longitudinal axis passes, so that, when the shaft is rotated within the probe by means of the handle, the plane is correspondingly rotated about the longitudinal axis, causing generation of swept image data in the interior of the body cavity. The image capture assembly further includes a radio frequency transceiver disposed in the probe and coupled to the piezo crystal array, the transceiver configured for transmitting the image data from the piezo crystal array to a computing device of a user.

Techniques of this disclosure are for a transducer array device, method and system. An ultrasound wrap for securing an array of piezoelectric transducers at a thoracic cavity anterior for echocardiology imaging, the ultrasound wrap including a transducer portion having an array of piezoelectric transducers mounted to an inner concave surface of a semi-rigid structure, and a securing portion extending from the transducer portion and comprising flexible material securely fitting around the thorax of a patient limiting the movement of the transducer portion.

A multi-modality cancer screening and diagnosis system is provided that allows cancer screening and diagnosis of a patient using at least two different and sequential three-dimensional imaging techniques without patient repositioning. The system includes a first three-dimensional image acquisition device, a second three-dimensional image acquisition device having a probe with a transmitter mounted thereon, and a positioning paddle for positioning and immobilizing an object to be imaged during the cancer screening and diagnosis procedure. The positioning paddle is designed to facilitate visualization of the breast in both three-dimensional modalities without movement of the patient, and preferably is designed to position the patient with comfort during a diagnosis procedure which uses both imaging modalities.

Provided are an ultrasound diagnosis apparatus and a method of displaying an ultrasound image. The ultrasound diagnosis apparatus includes: one or more processors configured to acquire ultrasound image data with respect to a fetus and generate an ultrasound image based on the ultrasound image data; a display configured to display the ultrasound image; and an input interface configured to receive position type information, wherein the one or more processors are further configured to determine positions of organs in the ultrasound image based on the position type information and control the display to display information about the organs together with the ultrasound image, based on the determined positions.

A guiding system and a guiding method for ultrasound scanning operation are provided. The guiding system includes a handheld guiding device, a display device, an ultrasound scanning device, a prompting device, and a control host. When the handheld guiding device generates a first physical motion, the control host detects the first physical motion and generates navigation prompting information accordingly. The prompting device is suitable for presenting the navigation prompting information to guide the ultrasound scanning device to move to generate a second physical motion. The control host captures an ultrasound image via the ultrasound scanning device and sends the ultrasound image to the display device at a guiding end for display.

A system for monitoring health during a water birth includes a health sensor configured to be coupled to a mother. The health sensor includes a first sensor configured to measure one or more health parameters of a mother, a fetus within the mother or both, a second sensor configured to generate a submerged signal representing whether the health sensor is at least partially submerged in water, and a transmitter configured to transmit communication signals representing data collected by the first sensor. One or more parameters of the communication signals change depending on whether the submerged signal represents that the health sensor is at least partially submerged.
