An ultrasound diagnostic apparatus performs transmission and reception of ultrasonic waves for forming focal points used to set sound velocities at predetermined timing such that sound velocities having been set for all of respective segment regions established by dividing a subject are all reset every predetermined number of frames. Owing to this configuration, it becomes possible for the ultrasound diagnostic apparatus to suitably reset sound velocities of ultrasonic waves in the subject and also reduce the amount of calculation for resetting sound velocities.

Various approaches for focusing an ultrasound transducer include introducing at least one transient acoustic reflector located in proximity to at least one target region; generating multiple sonications to the at least one target region; measuring a reflection signal of each of the sonications off the at least one transient acoustic reflector; selecting the measured reflection signals, and based at least in part on the selected reflection signals, adjusting a parameter value associated with at least one of the transducer elements so as to improve an ultrasound focus at the target region.

The present disclosure describes systems and methods for determining if a feature of interest is present in a volume or plane scanned by an imaging system. In examples, one or more imaging planes are analyzed for anatomical landmarks to determine whether a feature of interest is present. If the feature of interest is present, scan parameters may be determined to scan an adjusted volume that includes the feature of interest. In some applications, the adjusted volume may allow the imaging system to increase a volume rate.

An ultrasound diagnostic apparatus generates an ultrasound image based on an ultrasound signal acquired by an ultrasound probe having an ultrasound transducer. The ultrasound transducer transmits an ultrasound wave to an observation target and receives the ultrasound wave reflected from the observation target. The apparatus includes: an analysis unit configured to generate analysis data based on the ultrasound signal received from the observation target; and a correction unit configured to correct the analysis data using correction data based on first reference data and second reference data, the first reference data being obtained from an ultrasound signal received from a reference reflector by using the ultrasound transducer or another ultrasound transducer of a same type as that of the ultrasound transducer, the second reference data being obtained from the ultrasound signal received from the reference reflector by using still another ultrasound transducer of different type from that of the ultrasound transducer.

An ultrasound control unit (10) is for coupling with an ultrasound transducer unit (12). The control unit is adapted to control a drive configuration or setting of the transducers of the transducer unit, each drive setting having a known power consumption level associated with it. The control unit includes a control module (20) adapted to adjust the drive setting from a first setting to a second setting, the second having a lower associated power consumption that the first. The second setting is tested by an analysis module (16), the analysis module adapted to determine a measure of reliability of ultrasound data acquired by the transducer unit, for the purpose of deriving at least one physiological parameter, when configured in the second setting. The second setting is only used if its determined reliability passes a pre-defined reliability condition.

Ultrasound imaging devices, systems, and methods are provided. A guidance system for obtaining an ultrasound image, comprising a processor in communication with a camera and a display, the processor configured to obtain a first motion control configuration for repositioning an ultrasound imaging device from a first position towards a target image view of a subject's anatomy, the first motion control configuration determined based on a first predictive network; determine positional information associated with the ultrasound imaging device based on an image captured by the camera, the image including the subject's anatomy and the ultrasound imaging device positioned at the first position; and output, to the display, an instruction to reposition the ultrasound imaging device from the first position to a second position based on the first motion control configuration and the positional information associated with the ultrasound imaging device.

A bladder monitoring system includes a scanning system and a wearable bladder monitoring device (or patch). The scanning system obtains scan data that shows a bladder in a patient and identifies, based on the scan data, a placement location on the patient for the wearable bladder monitoring device. The scanning system indicates the placement location to a user; and identifies customization settings for one or more sensors of the wearable bladder monitoring device to enable the one or more sensors to detect extents of the bladder when the wearable bladder monitoring device is attached at the placement location.

Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

An example medical probe apparatus includes a main body; and a head which is detachably provided in the main body, and includes a transducer array configured to output an ultrasound for diagnosis of an object, the main body including: a transceiver configured to transmit and receive a signal to and from the transducer array through a plurality of channels; and at least one processor configured to control the transceiver to transmit a predetermined test signal to the transducer array of the head mounted to the main body, determine a probe type corresponding to the transducer array of the mounted head based on a feedback signal received through the transceiver in response to the test signal, and make the probe apparatus operate corresponding to the determined probe type.

There are provided an ultrasound diagnostic apparatus and an operation method of an ultrasound diagnostic apparatus capable of performing polarization processing during the execution period of ultrasound diagnosis without affecting the image quality of an ultrasound image. In the ultrasound diagnostic apparatus and the operation method of the ultrasound diagnostic apparatus of the invention, a trigger generation circuit generates a trigger for starting polarization processing. After a trigger is given, during the execution period of ultrasound diagnosis, in a non-diagnosis period which is a period other than a period for acquiring an image of each frame and during which transmission of ultrasound waves and reception of reflected waves for performing ultrasound diagnosis are not performed, within each frame time in which an image of each frame of an ultrasound image is acquired, a control circuit performs polarization processing on a plurality of ultrasound transducers.
