Electromagnetic energy is deposited into a volume, an acoustic return signal from energy deposited in the volume is measured, and a parametric map that estimates values of at least one parameter as spatially represented in the volume is computed. A reference level of a region of interest is determined, and upper and lower color map limits are specified, with at least one of them being determined in relation to the reference level. The parametric map is then rendered in the palette of a color map by mapping the estimated values of the parametric map onto the color map according to the color map limits. Two wavelengths of energy can be applied to the volume, and the parametric map computation can be adapted by applying an implicit or explicit model of, or theoretical basis for, distribution of electromagnetic energy fluence within the volume pertaining to the two wavelengths. The actual electromagnetic energy fluence caused by each wavelength has a propensity, due to variability within the volume, to differ from the modeled or theoretical electromagnetic energy fluence.

The first transmitting unit is used for transmitting a first push beam and the first push beam has a first transmitting frequency. The second transmitting unit is used for transmitting a second push beam and the second push beam has a second transmitting frequency. The receiving unit has a receiving frequency and is used for selectively receiving a reflective wave of the first push beam and the second push beam, wherein the receiving frequency is covered with the first transmitting frequency and the second transmitting frequency. The receiving unit, the first transmitting unit and the second transmitting unit are disposed in the casing side by side.

A medical diagnostic method, system and related equipment particularly adapted to diagnose disorders of the blood circulation serving the head and neck, and especially the brain. A preferred use of the system is early, rapid, accurate, diagnosis of stroke, especially whether the stroke is due to blockage of a blood vessel or leakage from the blood vessel.

A method is disclosed for generating sinograms by sampling a plurality of transducers acoustically coupled with the surface of a volume of tissue over a period of time after a light pulse at one wavelength, and after another light pulse at a different wavelength, and for processing those sinograms, reconstructing at least two optoacoustic images from the two sinograms, processing the two optoacoustic images to generate two envelope images and generating a parametric map from information in the two envelope images. In an embodiment, motion and tracking are determined to align the envelope images. In an embodiment, at least a second parametric map is produced from information in the same two envelope images. In an embodiment an ultrasound image is also acquired, and the parametric map is coregistered with and overlayed upon the ultrasound image, and then displayed.

A flexible variable frequency ultrasonic therapeutic probe based on thermoacoustic effect of a carbon nanotube film comprises an ultrasonic sound production element, and a heat dissipation layer and an acoustic matching layer located on both sides thereof. The sound production element comprises a carbon nanotube film, metal electrodes and wires, and the shape and size of the sound production element can be adjusted according to the actual functional requirements. When a signal is accessed into the sound production element, the carbon nanotube film produces a corresponding temperature change, which causes the surrounding media to expand and contract and to excite ultrasonic waves. The present invention greatly improves the coupling efficiency between the probe and the subject, reduces the energy loss of ultrasonic waves, and enhances the uniformity of the sound intensity distribution in the affected part.

The present invention relates to fetal monitoring and, more particularly, to an electronic external fetal monitoring system that includes a self adhering single use dermal patch including embedded sensors that can be attached to the skin of an expectant maternal patient and is configured to record fetal heart rate, uterine activity, and uterine integrity.

A system for acquiring ultrasound images of internal organs of a human body, comprises a scanner and at least a minimum number of components in, or associated therewith consisting of: i) an ultrasound probe head; ii) the at least one IMU, which comprises a three-axis accelerometer and a three-axis gyroscope; iii) electronic components for wired or wireless communication with remote terminals, and iv) a power source, wherein the 3-axis gyroscopes and 3-axis accelerometers of the IMU are calibrated by the manufacturer for offset, scale-factor, cross-axis sensitivity and initial orientation; and MEMS IMUs are calibrated by the user.

An ultrasound endoscope includes: an ultrasound transducer; a balloon groove in which a balloon band is fitted; a contact portion that constitutes a bottom surface of the balloon groove; a first wall portion that constitutes a proximal end side of the balloon groove and in which a first distance that is a distance from a center of a cross section orthogonal to an extension direction of the insertion portion to an outer circumference of the first wall portion is larger than a second distance that is a distance from the center of the cross section to the bottom surface; and a second wall portion that constitutes a distal end side of the balloon groove, in which a distance from the center of the cross section to an outer circumference of the second wall portion is larger than the second distance, and that includes a notch portion.

Provided is a device that transmits and receives an ultrasonic wave to and from an entire periphery of a specimen while preventing a movement of the specimen. An ultrasonic wave transmission and reception device includes: an oscillator array that is arrayed with an oscillator, the oscillator transmitting and receiving an ultrasonic wave; a fixing tool that is disposed between the oscillator array and the specimen and retains the specimen; and a drive mechanism that presses at least a part of the fixing tool against the specimen as to retain the specimen. An ultrasonic wave transmitted by the oscillator array passes through the fixing tool and irradiates on the specimen, and as for the oscillator array, the oscillator array and the fixing tool are disposed in a positional relationship such that the ultrasonic wave reflected by and/or passing through by the specimen and passing through the fixing tool is received.

Implementations described and claimed herein provide systems and methods for managing one or more patients. In one implementation, an imaging window is determined based on a location of a probe. A primary image cross-section for the imaging window is identified for the imaging window. At least one image is generated along the primary image cross-section using patient data captured using the probe. The at least one image is compared to an expected image contour scaffold of the primary image cross-section. The probe is commanded to fine-tune an imaging plane based on the comparison until the at least one image matches the expected image contour scaffold of the primary image cross-section.
