Abstract
A system and method for controlling rhythmic sensory stimulation provided to a subject with post-stroke depression, PSD, during an MRI scan. A control unit is configured to control a rhythmic sensory stimulation signal such that the signal is rhythmically synchronous to a scanning rhythm of an MRI scanner performing the MRI scan.
Claims16
A system comprising:
- a magnetic resonance imaging (MRI) scanner configured to obtain a sequence of images representative of brain activity of a subject during an MRI scan, wherein the MRI scanner provides a first rhythmic stimulation signal representative of noise of the MRI scanner;
- a sensory stimulation system configured to provide a second rhythmic stimulation signal to the subject during the MRI scan, wherein the second rhythmic stimulation signal is a user-perceptible signal including at least one of a visual signal, an audio signal, or a tactile signal;
- and
- a control unit configured to control the second rhythmic stimulation signal provided to the subject during the MRI scan, wherein the second rhythmic stimulation signal is controlled to be synchronized with a scanning frequency of the MRI scanner performing the MRI scan and the first rhythmic stimulation signal representative of noise of the MRI scanner, and wherein the first rhythmic stimulation signal and the second rhythmic stimulation signal provide an immersive multisensory stimulation therapy.
A computer-implemented method for controlling stimulation provided to a subject with post-stroke depression during an MRI scan, the computer-implemented method comprising:
- controlling a first rhythmic stimulation signal provided to the subject during the MRI scan, wherein the first rhythmic stimulation signal is a user-perceptible signal including at least one of a visual signal, an audio signal, or a tactile signal, and
- wherein the first rhythmic stimulation signal is controlled to be synchronized with a scanning frequency of an MRI scanner performing the MRI scan and with a second rhythmic stimulation signal, wherein noise associated with the MRI scanner provides the second rhythmic stimulation signal to the subject, and wherein the first rhythmic stimulation signal and the second rhythmic stimulation signal provide an immersive multisensory stimulation therapy for the post-stroke depression.
A computer implemented method comprising:
- receiving an input indicative of a rhythmic stimulation signal representative of noise produced by a magnetic resonance imaging (MRI) scanner during an MRI scan;
- outputting a sensory stimulation signal to an associated subject undergoing the MRI scan, wherein the sensory stimulation signal is a user-perceptible signal including at least one of a visual signal, an audio signal, or a tactile signal;
- controlling the output of the sensory stimulation signal to be synchronized with a scanning frequency of the MRI scanner and with the rhythmic stimulation signal representative of noise produced by the MRI scanner;
- and
- receiving a sequence of images representative of brain activity of the subject taken during the MRI scan;
- and
- analyzing an effect of the rhythmic stimulation on the subject based on the sequence of images, and wherein the rhythmic stimulation signal and the sensory stimulation signal provide an immersive multisensory stimulation therapy.
