Medical visualisation system

A monitor device operable to receive image data from a medical visualization device, the monitor device comprising:

• a housing, and
• a processing unit adapted to receive the image data from the medical visualization device and cause a display to display a graphical user interface,
• wherein the monitor device:
• displays a live representation of the image data within a first portion of the graphical user interface, and
• displays a stopwatch button within a second portion of the graphical user interface, the second portion and the first portion being non-overlapping,
• and wherein the monitor device, while displaying the live representation of the image data, is adapted to detect a first user input corresponding to selection of the stopwatch button, and in response to detection of the first user input the monitor device:
• activates a time of a stopwatch, and
• displays a timestamp table within the graphical user interface, wherein the timestamp table comprises an add timestamp button,
• and wherein the monitor device is adapted to detect a second user input corresponding to selection of the add timestamp button, and in response to detection of the second user input the monitor device:
• stores a first timestamp comprising a first timestamp value corresponding to the time of the stopwatch when detecting the second user input, and
• displays a first timestamp entry in the timestamp table comprising the first timestamp value.
