  • Publication number: 20230268069
    Abstract: A method for monitoring a medical intervention taking place in an operating room or examination room, or a medical examination on a patient by medical personnel includes acquiring sensor data from at least one acoustic sensor, of at least one individual among the medical personnel during the medical intervention or the medical examination. The sensor data is evaluated as regards recognition of stress and/or negative emotions of the at least one individual. When stress and/or negative emotions are recognized, at least one cause of the stress and/or of the negative emotions is determined using the sensor data and/or further optical, acoustic, haptic, digital, and/or other data acquired during the medical intervention or the medical examination. Measures are triggered to remediate the determined cause and/or to reduce the stress and/or the negative emotions of the at least one individual.

    Abstract: An object of this disclosure is to allow dose-specific alteration of the noise suppression in X-ray images, wherein the image quality may change only below the threshold of perceptibility. To achieve this, a method is provided for adjusting a parameter for noise suppression in X-ray imaging, in which quality functions are determined in relation to a variation of a noise suppression parameter. Maximum values of the variation are set for each quality function based on a threshold value. The variability of the noise suppression parameter may be limited according to the X-ray dose up to the set maximum value.
