Abstract: The invention provides for a method and an apparatus (300) for positioning an ultrasound patch on a surface of a subject. The apparatus includes a first fixing unit (210) and a second fixing unit (310) adapted to be fixed to a surface of the subject at a first location and second location, respectively, with a space of exposed surface of the subject between them. The apparatus further comprises a holding unit (260) for positioning on the exposed surface of the subject within the space between the fixing units, the holding unit being adapted to receive the ultrasound patch. The holding unit is adapted to be coupled with the first and second fixing units at the surface of the subject and, when the holding unit is coupled to the first fixing unit and the second fixing unit, the position of the holding unit is adjustable relative to the first fixing unit and the second fixing unit.

Abstract: The invention provides an ultrasound patch (710) comprising a first array group (720) comprising a primary transducer array (730) having a first orientation and a second array group (740) comprising at least two secondary transducer arrays (750) each having an orientation different from the first orientation. The second array group is arranged such that the at least two secondary transducer arrays are located at either side of the primary transducer array. The first array group or the second array group may be used to capture preliminary ultrasound data for positioning the ultrasound patch. The primary transducer array and the at least two secondary transducer arrays may comprise CMUTs, and the ultrasound patch may comprise a flip chip connection. Also disclosed are a system and a method for positioning the ultrasound patch on a surface of a subject.

Abstract: The present invention relates to peripheral perfusion measurement. In order to provide more detailed peripheral perfusion characteristics for better knowledge about a current situation, a device (10) for peripheral perfusion measurement is provided that comprises an image data input (12), a data processor (14) and an output interface (16). The image data input receives at least one perfusion angiographic 2D X-ray image of a region of interest of a subject's foot and a 3D foot-model comprising spatial perfusion-related parameters. The data processor registers the 3D foot-model with the foot in the at least one perfusion angiographic X-ray image. The registering comprises a pose-estimation of the foot in the 2D X-ray image. The information is mapped between the 2D image and the 3D foot-model based on the pose-estimation. Image processing modification instructions are identified based on the mapped information. Further, the at least one image signal is modified based on the image processing modification instructions. The output interface provides the at least one modified image signal. In a first example, a regional perfusion analysis is provided. In a second example, a normalization of the perfusion signal by the fraction of perfused tissue is provided. In third example, reporting in a 3D model is provided.

CPC classification number: A61B5/0261 , A61B5/02416
Abstract: An apparatus (and method) is for monitoring blood perfusion. A plurality of photoplethysmography, PPG, signals are acquired indicative of light detected in a region of interest of tissue at a plurality of respective locations within the region. The PPG signals are processed to determine an amplitude and preferably also a phase of each of the plurality of PPG signals, and a blood perfusion level is determined at the region of interest based on the amplitudes and preferably also the phases of the PPG signals.

Abstract: A method (100) for visualizing a section of a patient's vascular system (155) with an ultrasound image processing system (3) is disclosed. The method comprises receiving (103) ultrasound data generated by an ultrasound probe (10) being displaced across a part of the patients anatomy (150) containing the section of the patients vascular system, said ultrasound data comprising image data and Doppler data; generating (107) ultrasound images (170) from said image data, each ultrasound image corresponding to a subsection of the patients vascular system having a determined location within the patients vascular system and combining (109) said ultrasound images into a map (180) of said section of the patients vascular system; processing (111) the received Doppler data to obtain blood flow characteristics for the section of the patients vascular system; identifying (113) landmarks within the section of the patients vascular system based on the obtained blood flow characteristics; annotating (115) said map with said landmark identifications (181, 183); and generating (117) an output signal comprising said annotated map. Also disclosed are a computer program product and ultrasound image processing system for implementing this method.
