Abstract: A measurement device includes: a processing device and multiple sensors that capture tomographic information of a physiological structure. The sensors include a first sensor including a first transducer having a first frequency response with a first resonant frequency, and a second sensor including a second transducer having a second frequency response with a second resonant frequency different from the first resonant frequency. The first frequency response partially overlaps with the second frequency response. The second transducer transmits a signal that is reflected by the physiological structure to create a reflected signal, the first transducer generates a first received signal from the reflected signal, the second transducer generates a second received signal from the reflected signal, and the processing device normalizes the first received signal with the second received signal or the second received signal with the first received signal.

Abstract: The invention provides a method for guiding the acquisition of ultrasound data. The method begins by obtaining ultrasound data from a plurality of data acquisition planes and performing spatial registration of the data acquisition planes. A number of vessels are then identified in each data acquisition plane. A location of a vessel bifurcation is then identified based on the spatial registration of the data acquisition planes and the number of vessels in each data acquisition plane. A guidance instruction is generated based on the location of the vessel bifurcation, wherein the guidance instruction is adapted to indicate a location to obtain further ultrasound data.

Abstract: A portable imaging system for visualizing a biological target structure by a tracking element introduced therein, including: a control unit with a memory for storing at least one ultrasound image of the target structure, a probe to be removably fixed to a biological fixing structure surrounding at least partially the target structure, the probe being connected to the control unit, and a positioning assistance module of the probe. The probe is capable of detecting the tracking element by means of ultrasound, the control unit being able to locate it, in real time, inside the target structure, so as to characterize it geometrically and create the ultrasound image. The control unit can also display it on a display device. The ultrasound image allows rapid diagnosis to be made independently of any location and environment.

Abstract: In accordance with a method for characterization of particles in a fluid-filled hollow structure, an ultrasound signal with a frequency spectrum, which exhibits a local maximum at a variable measurement frequency, is emitted in the direction of a part area of the hollow structure and reflected components are detected. The measurement frequency is tuned in a predetermined measurement interval, and depending on the detected reflected components, a spectral response curve is acquired as a function of the measurement frequency. Depending on the response curve, at least one characteristic property for a part of the particles located in the part area of the hollow structure is determined. The characteristic property includes a measure for an adhesion of the particles of the part of the particles located in the part area of the hollow structure.

Abstract: An ultrasound catheter includes a distal port and a proximal port and is adapted to provide fluid communication between the distal port and the proximal port. The ultrasound catheter includes an ultrasound transducer. The ultrasound catheter may be advanced through a guide catheter that is positioned within a patient's vasculature and is fluidly coupled with the patient's blood. A vacuum may be applied to the proximal port, causing the patient's blood to be slowly pulled into the ultrasound catheter through the distal port such that any air near the ultrasound transducer is replaced with the patient's blood and the ultrasound transducer is surrounded by the patient's blood, which is an optimal imaging medium. The ultrasound transducer may be operated to obtain ultrasound images while applying the vacuum to the proximal port.

Abstract: The invention generally relates to medical imaging systems that instantly and/or automatically detect borders. Embodiments of the invention provide an imaging system that automatically detects a border at a location within a vessel in response only to navigational input moving the image to that location. In some embodiments, systems and methods of the invention operate such that when a doctor moves an imaging catheter to a new location with in tissue, the system essentially instantly finds, and optionally displays, the border(s), calculates an occlusion, or both.
