Systems and methods for automatically measuring and labeling follicles depicted in two-dimensional (2D) image slices of an ultrasound volume are provided. The method includes receiving an ultrasound volume of an ovary having follicles. The method includes causing a display to present, one at a time, 2D image slices extracted from the ultrasound volume. The method includes receiving a user indication identifying a follicle at a maximum size in a first 2D image slice of the ultrasound volume presented at the display. The method includes automatically segmenting the follicle in the ultrasound volume. The method includes automatically measuring the follicle in the first 2D image slice to generate a measurement presented at the display. The method includes automatically labeling the follicle in the first 2D image slice presented at the display and in any other of the parallel 2D image slices depicting the follicle that is subsequently presented at the display.

An intravascular sensor device can be used to guide treatment of a diseased blood vessel in the body of a patient. In some examples, the intravascular sensor device includes a pressure sensor and an ultrasound transducer. The intravascular sensor device is used to measure a pressure within the diseased blood vessel and acquire an ultrasound image of the diseased blood vessel. The pressure may be measured during hyperemic blood flow that is caused by a pharmacologic vasodilator drug. The measured pressure can be used to calculate a fractional flow reserve value. The ultrasound image can be used to determine a physical dimension of the blood vessel, such as cross-sectional area. The fractional flow reserve value and physical dimensions of the blood vessel can be used to optimize patient treatment.

Embodiments provide an ultrasound treatment system. In some embodiments, the system includes a removable transducer module having an ultrasound transducer. In some embodiments, the system can include a hand wand and a control module that is coupled to the hand wand and has a graphical user interface for controlling the removable transducer module, and an interface coupling the hand wand to the control module. The interface may provide power to the hand wand or may transfer a signal from the hand wand to the control module. In some embodiments, the treatment system may be used in cosmetic procedures on at least a portion of a face, head, neck, and/or other part of a patient.

A device includes an ultrasound probe including an elongated neck insertable in a patient and rotatable around a first longitudinal axis, an ultrasound transducer, and an elongated body rotatable around a second longitudinal axis that is parallel to and offset from the first longitudinal axis. The elongated body is removably attached to a probe mounting structure. A shaft is attached to the probe mounting structure, where rotation of the shaft causes corresponding rotation of the probe mounting structure and the attached elongated body of the ultrasound probe. The shaft defines a longitudinal shaft channel in an interior portion and a longitudinal shaft groove extending from a surface of the shaft to the longitudinal shaft channel. A cable is insertable into the longitudinal shaft channel through the longitudinal shaft groove, and enters an internal channel of the ultrasound probe through the longitudinal shaft channel enabling electrical connection with the ultrasound transducer.

An ultrasonic imaging method and an ultrasonic imaging system are provided herein. The ultrasonic imaging system includes: a scanning assembly having an ultrasonic transducer to send ultrasonic signals to a tissue to be scanned and acquire a plurality of ultrasonic echo signals at a plurality of positions; a processor to receive the plurality of ultrasonic echo signals acquired at the plurality of positions, and generate an ultrasonic image corresponding to each of the plurality of positions; a display to display the ultrasonic images; and a user input unit to select the ultrasonic image corresponding to any specific position and send an input signal that is configured to control movement of the ultrasonic transducer, driven by a driving device, to the specific position. Also provided in the present invention is an ultrasonic imaging method using the system.

Disclosed are a bladder monitoring apparatus which accurately determines a bladder status of a subject based on an ultrasonic image and a posture of the subject and a method for controlling the bladder monitoring apparatus. The bladder monitoring apparatus includes a processor, a memory configured to operably connected to the processor and store at least one code executed by the processor, and a transceiver configured to receive a reflection ultrasonic signal from a subject and a posture sensing signal obtained by sensing a posture of the subject based on a sensor, and the memory may store a code which is executed by the processor to cause the processor to determine the bladder status of the subject by applying the machine learning-based learning model to an ultrasonic image generated from the reflection ultrasonic signal and posture information generated based on the posture sensing signal.

A multimodal intravascular analysis uses a structural intravascular analysis modality to compensate for a chemical analysis modality. Examples of structural analysis are IVUS, OCT, including optical coherence domain Reflectometry (OCDR) and optical frequency domain imaging (OFDI), and/or sonar rangefinding. Examples of chemical or functional analysis are optical, NIR, Raman, fluorescence and spectroscopy, thermography and reflectometry. In one example, the structural analysis is used to characterize the environment structurally, such as catheter head-vessel wall distance. This information is then used to select from two or more algorithms which are depth specific (e.g. shallow vs. deep), to achieve improved accuracy in the chemical or functional analysis.

Disclosed are embodiments of devices and methods for imaging the inside of a body part, such as a blood vessel. In particular embodiments, a catheter has a chamber within which is a transducer. A wire guide channel extends throughout the length of the catheter. The transducer is rotatable about the wire guide channel and the transducer is driven by a cable or other device that is connected to a motor which is located outside the catheter. In one form, a torque cable connects the transducer to the motor. In other embodiments, a pusher piece having a plurality of lumens is positioned in the catheter. Each of the lumens is sized to receive a cable, wire, and/or flushing fluid. The lumens maintain the orientation and separation of the cables, wires, and/or to flushing fluid.

A catheter is disclosed with a priming hole for exhaust at a distal portion of the catheter, the priming hole being used when filling with a priming solution is performed, and movably and rotatably accommodates an imaging core. The catheter includes a first connector that is provided at a rear end portion of the catheter and is supported by a fixed connector portion of a motor drive unit included in an imaging apparatus for diagnosis and a second connector that is supported by a movable connector portion of the motor drive unit. The catheter includes a reservoir, which is provided in the first connector and has a volume which decreases depending on a pull-out length of the second connector from the first connector, and a supply route, through which a priming solution injected from a priming injection port is supplied to the reservoir.

An ultrasound probe has a two dimensional matrix array transducer and a digital microbeamformer. The microbeamformer comprises a plurality of transmitters and amplifiers coupled to elements of the array transducer, a plurality of low power analog to digital converters and digital beamforming circuitry coupled to the amplifiers, a microbeamformer controller, a power supply and a USB controller which cumulatively consume three watts or less.
