Systems, apparatus, and method of monitoring a position of a joint. An inertial monitoring unit is configured to be coupled to a portion of a patient, such as a thigh. Another inertial monitoring unit is configured to be attached to another portion of the patient, such as a shank, that is connected to the other portion by a joint, such as a knee. The inertial monitoring units detect motion of their respective portions of the patient and transmit data indicative of this motion. These transmissions may be received by a computer and used to determine an orientation of the joint. The inertial monitoring units may also be coupled to vibration detection units and/or ultrasound modules that provide additional data regarding a condition of the joint.

An ultrasonic system may include: an oral care device including: a head; a plurality of teeth cleaning elements extending from a first side of the head; and an ultrasound module including an ultrasound transceiver positioned in the head, the ultrasound transceiver configured to produce an ultrasound signal on the first side of the head and to generate a detection signal from a reflected ultrasound signal; and a processing module operably coupled to the ultrasound module to receive the detection signal; wherein the processing module includes a programmable processor configured to process the detection signal non-linearly with respect to time by first identifying a first reflection representing a surface of a tooth and then determining whether a second reflection peak is present in the detection signal at a time prior to the first reflection peak, the second reflection peak representing a biofilm on the surface of the tooth.

To provide an ultrasound imaging apparatus capable of displaying an ultrasound stitched image in which an analyte can easily grasp the state of the analyte, an ultrasound imaging apparatus is provided with an ultrasound image generation module which receives ultrasound waves transmitted from a plurality of mutually different positions on the surface of an analyte and reflected in the inside of the analyte and generates ultrasound images corresponding to the respective positions, an image stitcher module which synthesizes the ultrasound images at the respective positions and generates a stitched image of the cross section of the analyte, and a rotation angle adjusting module which adjusts the angle of the stitched image and orients a specific portion included in the stitched image in a predetermined direction.

Improved systems and methods for diagnosing an injury of a patient. The system and methods provide for more accurate scans of the injury thereby enabling a combat medic, a medical technician, or even untrained individuals to quickly diagnose the injury. By providing more accurate information, the systems and methods provide the technician with additional information regarding treatment options, such as whether to transport the patient or treat the patient in place, potential for aspiration, and other information about dangerous fluid build-up such as size, depth, and types of surrounding tissues, thereby increasing survivability of the patient. The systems and methods can also provide a diagnosis of the injury as well as suggestions on actions to take to treat the patient.

The present invention provides an ultrasonic imaging device, comprising: an imaging assembly, the imaging assembly comprising an ultrasonic transducer for imaging tissue to be imaged; an adjustable arm, wherein one end of the adjustable arm is connected to the imaging assembly; a counterweight, the counterweight being connected to the other end of the adjustable arm through a cable; a frame, the frame being capable of guiding movement when the counterweight and/or adjustable arm moves; and a transmission assembly, the transmission assembly comprising a driving device and a transmission belt, wherein the driving device is connected to the transmission belt, and the transmission belt is connected to the counterweight; the driving device is capable of acting on the counterweight through the transmission belt, so as to adjust pressure applied by the imaging assembly onto the tissue to be imaged. The present invention further provides some imaging methods using the ultrasonic imaging device.

A thermoacoustic system and method of use to receive an ultrasound system output from an ultrasound system, via an existing communication port on the ultrasound system. The thermoacoustic system includes a radio-frequency emitter, at least one thermoacoustic transducer, a processor, and a display that is integrated with the processor and configured to display an image that is a function of the ultrasound system output and data from the at least one thermoacoustic transducer.

A bladder urine volume monitoring system and a bladder urine volume monitoring method are provided. The bladder urine volume monitoring system includes at least one ultrasound patch, at least one muscle stimulation patch, and a control circuit. The ultrasound patch is configured to be attached to a surface of an organism to detect a urine volume in a bladder. The muscle stimulation patch is configured to be attached to the surface of the organism to stimulate a muscle of the bladder. The control circuit is coupled to the ultrasound patch and the muscle stimulation patch. The control circuit drives the ultrasound patch to detect the urine volume in the bladder in a first period. The control circuit drives the muscle stimulation patch to stimulate the muscle of the bladder in a second period.

Systems and methods for non-invasive fat reduction can include targeting a region of interest below a surface of skin, which contains fat and delivering ultrasound energy to the region of interest. The ultrasound energy generates a thermal lesion with said ultrasound energy on a fat cell. The lesion can create an opening in the surface of the fat cell, which allows the draining of a fluid out of the fat cell and through the opening. In addition, by applying ultrasound energy to fat cells to increase the temperature to between 43 degrees and 49 degrees, cell apoptosis can be realized, thereby resulting in reduction of fat.
