An ultrasonic-image-construction apparatus can construct an ultrasonic-tomographic image of a thin, layer-structured target object to be measured relatively easily and highly accurately in a manner in which such layered structure is easily understood. An ultrasonic transducer of an ultrasonic-image-constructing apparatus transmits ultrasonic waves to the target object. A reference substance makes contact with a base substrate, with such ultrasonic waves being incident on the target object via the base substrate, then receives an impulse response of an ultrasonic waveform. A computing means performs calculation to estimate acoustic-physical-property distribution in consideration of the multiple-reflections influence based on normalized-impulse information obtained from impulse-response information of such ultrasonic waveform incident on the reference substance and from impulse-response information of such ultrasonic waveform incident on the target object. The image-construction means constructs acoustic-physical-property-image data based on acoustic-physical-property distribution in the depth direction obtained by computing means.

An improved system and method of endobronchial imaging of lung nodules comprises the introduction of a perfluorocarbon (PFC) liquid into pulmonary passages of the lungs, the introduction of which enables better coupling between an endobronchial ultrasonic imaging system and a target tissue site within the pulmonary passages of the lungs, the improved coupling between the ultrasonic imaging system and a target tissue site being imparted by the removal (at least in part) the air interface present between the ultrasonic imaging system and the surface of the target tissue site. Furthermore, the unique properties of perfluorocarbon liquids (for example, the properties of superb biocompatibility, high affinity for dissolving oxygen, and extremely low surface tension) further position these substances to be particularly well-suited for this application.

The present disclosure describes systems and methods configured to determine shear wave velocity and tissue stiffness levels of thin tissue of finite size, also referred to as bounded tissue, via shear wave elastography. Systems can include an ultrasound transducer configured to acquire echoes responsive to pulses transmitted toward a tissue. Systems can also transmit a push pulse into the tissue for generating shear waves, and tracking pulses intersecting the shear waves. The system can also apply a directional filter to received echo data and generate directionally filtered shear wave data based on a dimension and angular orientation of the bounded target relative to the ultrasound transducer. The system can estimate velocities of the shear waves at different shear wave frequencies based on the filtered shear wave data and angular orientation relative to the transducer, and determine a tissue stiffness value independent of the shape or form of the tissue.

The embodiments herein provide a system for calibration-free cuff-less evaluation of blood pressure. The system includes an ultrasound-based arterial compliance probes and a controller unit connected to the said probe. The ultrasound transducers are configured to measure the change in arterial dimensions, pulse wave velocity, and other character traits of an arterial segment over continuous cardiac cycle, which is then used to evaluate blood pressure parameters without any calibration procedure using dedicated mathematical models. The pressure sensor/force sensor/bio-potential transducers/accelerometric sensors are configured to measure a pressure acting on a skin surface at a measurement site, an internal arterial transmural pressure level, an applied pressure or a hold-down pressure on the skin surface or an arterial site, biopotential and/or plethysmograph signal, arterial vibrations acting on the measurement site as a function of the arterial pressure and the mechanical characteristics and/or a function of the applied/hold-down pressure and/or function of external factors.
