The present invention relates to a piece of clothing (10) intended to be worn by a user so as to cover a part of the user's body. This piece of clothing (10) comprises a flexible clothing element (11) covering said part of the user's body as well as a generator (14) of electrical signals and at least one transducer (12) integral with said flexible clothing element (11). Said at least one transducer is arranged to convert said electrical signals from the electrical signal generator (14) into ultrasounds and to transmit the ultrasounds generated by this transducer (12) to said part of the user's body covered by this flexible clothing element. The piece of clothing is characterised in that said at least one transducer (12) is arranged to emit ultrasounds having at least two different acoustic intensities comprised in at least two distinct intensity ranges.

The present invention further relates to a method of monitoring biological cells of a user, which method uses the piece of clothing as described above. The method comprises the following steps: selecting an acoustic intensity from at least two distinct acoustic intensity ranges; energising the transducer (12) so as to emit ultrasonic waves according to the selected acoustic intensity; emitting ultrasonic waves from the transducer (12), said ultrasonic waves having an acoustic intensity within said selected intensity range.

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 system is disclosed for determining a position and a change in the position of an anatomical structure. The system utilizes a surgical navigation system and a substrate that is capable of being removably mounted to an outer surface of a body. A sensor is attached to the substrate to be tracked by the surgical navigation system. An ultrasonic imaging device is attached to the substrate to determine a position of the anatomical structure. A first circuit calculates a global position of the anatomical structure by correlating a position of the sensor and the position of the anatomical structure. The first circuit determines the global position without the use of an image of the anatomical structure, and may do so without the use of a reference device invasively affixed to the body. A second circuit displays the global position of the anatomical structure.

A method of evaluating a cerebrovascular health of a patient includes causing a patient to exercise for an exercise duration at an exercise intensity, collecting cerebrovascular information from the patient during the exercise duration, collecting cardiovascular information from the patient during the exercise duration, correlating the cerebrovascular information to the cardiovascular information to create a correlated cerebrovascular curve, and determining a cerebrovascular health and viability for cerebrovascular therapy.

Disclosed are an ultrasound imaging system for analysis of a body composition and an operation method of an ultrasound imaging system which is designed for analysis of a body composition. An ultrasound imaging system may include: a scan device into which an object is insertable; an ultrasonic probe connected to a part of the scan device; a controller configured to control the ultrasonic probe to emit a transmission ultrasonic signal to the object at multiple positions at the scan device, and receive a reflection ultrasonic signal reflected from the object; and an image processor configured to generate multiple 2D ultrasound images based on reflection ultrasonic signals received at the multiple positions at the scan device, respectively, and generate a 3D ultrasound image based on the multiple 2D ultrasound images.

A system for monitoring blood flow in a patient, the system comprising: a single-element disc-shaped ultrasound transducer for fastening to the patient and a controller subsystem. The controller subsystem is configured to: control the ultrasound transducer to transmit a series of plane-wave pulses into the patient in a propagation direction; sample reflections of the plane-wave pulses, received at the ultrasound transducer, from a region within the patient, to generate pulse-Doppler response signals; and process the pulse-Doppler response signals to calculate a blood flow curve for waveform analysis.

Provided is a non-invasive system and method of determining pennation angle and/or fascicle length based on image processing. An ultrasound scan image is processed to facilitate distinguishing of muscle fiber and tendon. The processed ultrasound scan image is then analyzed. The pennation angle and/or fascicle length is determined based on the analysis. An example method includes receiving an ultrasound scan image of at least a portion of a skin layer as disposed above one or more additional tissue layers, the image provided by a plurality of pixels. The method continues by introducing noise into the pixels of the image and thresholding the pixels of the image to provide a binary image having a plurality of structural elements of different sizes. The method continues with morphing the structural elements of the binary image to remove small structural elements and connect large structural elements. With this resulting image, the method distinguishes muscle fiber and tendon from remaining elements and determines the pennation angle and/or the fascicle length from the muscle fiber and the tendon. Associated apparatuses and computer program products are also disclosed.

The present invention relates to a hand-held volume measuring device configured for being clamped onto part of a urinary catheter and for measuring the volume of urine miming through the urinary catheter over a period of time.

Ultrasonic energy is used for treating degenerative dementia. A focal point of an ultrasonic transducer beam is directed at a target area of the brain to promote removal of substances that accumulate in the interstitial pathways that are at least partially responsible for the degenerative dementia. In one example, the target area of the brain may comprise the hippocampus and the degenerative dementia may be Alzheimer's disease. The ultrasonic beam may stimulate brain tissue at a frequency that corresponds to a naturally occurring deep sleep burst frequency of neurons and subsequent astrocyte activation patterns that drive a convective process responsible for brain solute disposal. For example, the transducer may generate a burst frequency of between 1-4 hertz to stimulate deep sleep brain functions that help remove amyloid plaque.
