    摘要: System (SYS) and related method for imaging support. The system comprises an input interface (IN) for receiving an input image (I1) of a patient acquired by an imaging apparatus (IA). The input image was previously assessed by an image quality assessment module (IQM) and was awarded an image quality, IQ, score. The system's imaging triaging module (TL) retrieves from an image database (DBI) of prior assessed images, a corresponding image (I0) that corresponds to the input image. The corresponding image is a prior image of patient. The imaging triaging module (TL) provides a decision, based on the first IQ score and a second IQ score of the corresponding image (I0), if any, whether or not to acquire a new image (I2) of the patient by the imaging apparatus (IA). The risk of unnecessary retakes can be reduced, thus saving time, dose, and reducing wear-and-tear of the imaging apparatus.

    摘要: The present invention relates to a device, system and method for determining a respiration rate of a subject. The device presented comprises an input interface for obtaining a red and/or an infrared photoplethysmography, PPG, signal, a feature signal unit configured to extract a first sequence of features from the PPG signal and to generate a first feature signal from said sequence of features, a resampling unit configured to resample with a resampling function the first feature signal to yield a resampled signal with a constant sampling rate and/or to resample a first derivative to yield a resampled first derivative with a constant sampling rate, a transformation unit configured to calculate a Fourier transform of the resampled signal to yield a transformed resampled signal or to calculate a Fourier transform of the resampled first derivative to yield a transformed resampled first derivative, and an extraction unit configured to extract from the transformed resampled signal a first respiration rate or from the transformed resampled first derivative the first respiration rate, wherein the first sequence of features is a sequence of phases of the first harmonic of a heart beat of the subject with respect to a start of the heart beat and wherein the first feature signal corresponds to the sequence of phases.
