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.

Abstract: An imaging system (IS), comprising an image acquisition unit (AQ) for acquisition of image data (I1) of an object (OB). The image acquisition is based on an imaging signal imitable by the unit (AQ) to interact with the object. The image acquisition unit (AQ) is adjustable to operate at different acquisition parameters that determine a property of the imaging signal. A predictor component (PC) predicts, based at least on the acquired image data (I1), one or more properties of the object. An acquisition parameter adjuster (PA) adjusts, based on the predicted object properties, the acquisition parameter at which the image acquisition unit (AQ) is to acquire follow-up image data (I2).

Abstract: The invention relates to the field of intravascular ultrasound (IVUS) imaging IVUS images of a vessel (6) are provided, which have been determined based on IVUS signals acquired at different acquisition locations (9, 10) along the length of the vessel and at different acquisition times. Moreover, pressure values are provided, which are indicative of the pressure within the vessel at the acquisition times, wherein a combined IVUS image is generated by combining provided IVUS images that have been determined based on IVUS signals acquired at acquisition times at which the pressure values differ by less than a predefined deviation threshold from a reference pressure value. This use of the pressure within the vessel as a selection criterion for combining IVUS images can ensure that only IVUS images are combined, which correspond to a same vessel wall motion state, thereby reducing artifacts in the combined IVUS image.

Abstract: A device includes a light source, a camera, a memory and a processor. The light source emits emission light to a wound at a plurality of wavelengths. The camera detects backscattered light generated based on the emission light. The memory stores instructions. The processor executes the instructions. When executed by the processor, the instructions cause the device to record an image based on the backscattered light; quantify a degree of infection of the wound based on the image, and output an indication of the degree of infection.

Abstract: An image analysis method and device is for detecting failure or error in an image segmentation procedure. The method comprises comparing (14) segmentation outcomes for two or more images, representative of a particular anatomical region at different respective time points, and identifying a degree of consistency or deviation between them. Based on this derived consistency or deviation measure, a measure of accuracy of the segmentation procedure is determined (16).

Abstract: A stress prediction device for predicting mechanical stress exerted to a deformable object due contact between the object and an external device that is to be inserted into the object at an intended insertion position comprises a segmentation unit configured to access generic model data representing a generic reference object that comprises predefined secondary landmark features at predefined landmark positions, which are not identifiable using a predefined imaging technique, and pre-insertion object image data acquired using the imaging technique. It provides segmented object model data which comprises associated mapped landmark position data indicative of mapped landmark positions of the secondary landmark features. A stress determination unit determines and provides predictive stress information indicative of mechanical stress exerted to at least one of the secondary landmark features at the associated mapped landmark position due to mechanical contact between the object and the external device.

Abstract: Provided is a method (200) for generating a combined anatomical model of a heart. The method comprises receiving (220) a non-contrast agent-enhanced ultrasound image of a left ventricular region of the heart and receiving (240) a contrast agent-enhanced ultrasound image of the left ventricular region of the heart. Image registration (260) is performed on the respective non-contrast agent-enhanced and contrast agent-enhanced ultrasound images, such that the respective images are aligned. Combined segmentation (270) of the aligned non-contrast agent-enhanced and contrast agent-enhanced ultrasound images is then carried out to generate the combined anatomical model. The combined segmentation (270) uses features of both of the aligned non-contrast agent-enhanced and contrast agent-enhanced ultrasound images as target points. Further provided is a processor arrangement adapted to implement the method and an ultrasound system comprising the processor arrangement. A computer program product comprising computer program code means adapted to implement the method is also provided.
