Bore based medical system comprising a camera carrier configured to be mounted in the bore-based medical systems and utilized for positioning and monitoring of patients during radiotherapy treatment

A bore-based radiotherapy medical system comprising:

• a gantry including a rotatable ring disposed in a gantry housing, the rotatable ring having mounted thereon a radiotherapy beam source configured to emit a radiotherapy beam focused at an iso-center of the bore based medical system, wherein the rotatable ring is configured to rotate at least partly around the through-going bore, wherein said gantry housing includes a bore wall defining a circumference of said through-going bore;
• a movable couch configured to be moved into and out from the through-going bore;
• and
• a camera carrier configured to be mounted inside an internal space of the gantry housing between the bore wall and an opposing wall of the gantry housing, or on a surface of the bore wall facing the through-going bore, the camera carrier being configured to monitor and/or track patient motion inside the through-going bore during radiotherapy,
• wherein the camera carrier includes at least two treatment monitoring cameras mounted in a direction toward the through-going bore and together configured to cover a field of view including said iso-center focus point of the bore based medical system, wherein said two treatment monitoring cameras are configured to record images of the patient lying on said movable couch during radiotherapy treatment so as to allow monitoring and/or tracking of any motion performed by said patient.
