A medical visualisation system comprising a visualisation device having an image sensor configured to generate image data indicative of a view from the visualisation device, the medical visualisation system further comprising a monitor device operable to receive the image data as the image data is being generated by the image sensor, the monitor device comprising a first housing extending in a first direction from a first housing side to a second housing side and in a second direction perpendicular to the first direction from a third housing side to a fourth housing side, the monitor device comprising a touch sensitive display accommodated in the first housing and having a first length in the first direction and a second length in the second direction, the monitor device displays with the touch sensitive display a graphical user interface, wherein the monitor device: - opens a procedure session; - displays a live representation of the image data within a first portion of the graphical user interface; - displays one or more actionable items within a second portion of the graphical user interface, wherein the one or more actionable items comprise an image capture button, the second portion and the first portion being non-overlapping; and - displays a folder icon within a background portion of the graphical user interface, the background portion and the first portion being non-overlapping, and wherein the monitor device is further adapted to detect a first user input corresponding to selection of the image capture button, and in response to detection of the first user input, the monitor device: - stores a first image file corresponding to the image data received when the first user input was detected; - associates the first image file with the procedure session; and - displays within the background portion of the graphical user interface a first representation of a still image corresponding to the stored first image file; after a predetermined delay after detection of the first user input, the monitor device displays an animation of transitioning the first representation to the folder icon. the medical visualisation system further comprising a monitor device operable to receive the image data as the image data is being generated by the image sensor, the monitor device comprising a first housing extending in a first direction from a first housing side to a second housing side and in a second direction perpendicular to the first direction from a third housing side to a fourth housing side, the monitor device comprising a touch sensitive display accommodated in the first housing and having a first length in the first direction and a second length in the second direction, the monitor device displays with the touch sensitive display a graphical user interface, wherein the monitor device: - opens a procedure session; - displays a live representation of the image data within a first portion of the graphical user interface; - displays one or more actionable items within a second portion of the graphical user interface, wherein the one or more actionable items comprise an image capture button, the second portion and the first portion being non-overlapping; and - displays a folder icon within a background portion of the graphical user interface, the background portion and the first portion being non-overlapping, - opens a procedure session; - displays a live representation of the image data within a first portion of the graphical user interface; - displays one or more actionable items within a second portion of the graphical user interface, wherein the one or more actionable items comprise an image capture button, the second portion and the first portion being non-overlapping; and - displays a folder icon within a background portion of the graphical user interface, the background portion and the first portion being non-overlapping, and wherein the monitor device is further adapted to detect a first user input corresponding to selection of the image capture button, and in response to detection of the first user input, the monitor device: - stores a first image file corresponding to the image data received when the first user input was detected; - associates the first image file with the procedure session; and - displays within the background portion of the graphical user interface a first representation of a still image corresponding to the stored first image file; - stores a first image file corresponding to the image data received when the first user input was detected; - associates the first image file with the procedure session; and - displays within the background portion of the graphical user interface a first representation of a still image corresponding to the stored first image file; after a predetermined delay after detection of the first user input, the monitor device displays an animation of transitioning the first representation to the folder icon.
