    Abstract: The present invention relates to a method (10) for monitoring the wakefulness of an imaged subject dining an MRI examination. The method comprises acquiring (11) at least one magnetic resonance image of the subject using an MRI system (100), and determining (13) a wakefulness measure based on at least a part (I) of the acquired image or images and/or on EEG data obtained from the imaged subject during the acquisition. The method also comprises generating (14) at least one signal if the determined wakefulness measure indicates that the subject has fallen asleep, has woken up and/or is predicted to transition from an wake to a sleep state and/or vice versa. The signal is generated during the acquisition (11) and/or before removing the subject from the MRI system. Further aspects of the invention relate to computer program products, computer systems and MRI systems.

    Abstract: According to an aspect, there is provided a computer-implemented method for determining a sleep schedule (20; 40; 60) for a subject. The method comprises obtaining (101) information indicating a shift working pattern for the subject, the shift working pattern comprising at least one night shift, information indicating a required duration of sleep for the subject, and information relating to any personal activities to be undertaken by the subject during the day before or day after the at least one night shift. The method also comprises analyzing (103) the obtained information to determine a sleep schedule (20; 40; 60) for the subject. The sleep schedule (20; 40; 60) comprises two or more sleep windows in the day before or day after the at least one night shift in which the subject is to sleep, with the two or more sleep windows being scheduled according to the required duration of sleep for the subject and according to any personal activities to be undertaken by the subject.

    Abstract: The present invention relates to a method (10) for monitoring the performance of a predetermined test task executed by a subject during an fMRI examination. The method comprises acquiring (11) a timeseries of fMRI images and providing (12) a sensory stimulus to the subject during the acquisition in accordance with the predetermined test task. The method comprises determining (13), after the sensory stimulus, an activity measure indicative of brain activity in at least one predetermined region of interest, and generating (14) at least one signal when the activity measure is indicative of a poor performance of and/or compliance to the predetermined test task. The signal is generated during the acquisition of the time series and/or before removing the subject from the magnetic resonance imaging system. Further aspects of the invention relate to computer program products, computer systems and MRI systems.

    Abstract: A computer-implemented method (100) of producing a sleep evaluation for a user for use with a sleep therapy is disclosed. The method comprises, with a processor arrangement (12), receiving (122) a perceived value of a sleep parameter from the user, said sleep parameter corresponding to sleep behavior of said user at a point in time during said sleep therapy; receiving (124) sleep monitoring data from an electronic sleep monitor, said sleep monitoring data incorporating an objective value of said sleep parameter at said point in time; and, in case of the perceived value being different to the objective value, processing the sleep monitoring data such as to augment (132) said objective value into a further value of said sleep parameter to reduce the discrepancy between the perceived value and the objective value; and producing (134) a sleep evaluation output for the user comprising at least the further value of said sleep parameter. Also disclosed is a computer program product for implementing such a method (100) on a processor arrangement (12) and a sleep monitoring system (1) adapted to implement such a method (100).

    Abstract: :The present invention relates to an apparatus (10) for determining and/or assessing depression severity of a patient. The apparatus comprising: an input unit (20); an image display unit (30); at least one sensor (40); and a processing unit (50). The image display unit is configured to present a plurality of images to a patient and the plurality of images are of different human facial expressions. The at least one sensor is configured to acquire information relating to the patient's viewing of the plurality of images. The input unit is configured to provide the processing unit with the information relating to the patient's viewing of the plurality of images. The input unit is configured to provide the processing unit with MRI scan image data of the patient. The MRI scan image data of the patient comprises MRI scan image data of at least one part of the patient's brain associated with recognition of facial expressions and/or associated with affective disorders. The processing unit is configured to determine and/or assess depression severity of the patient comprising utilization of the information relating to the patient's viewing of the plurality of images and the MRI scan image data of at least one part of the patient's brain associated with recognition of facial expressions
