Cleaning system of a medical imaging facility

A computer-implemented method for operating a cleaning system of a medical imaging facility, wherein the medical imaging facility has an outer usable surface exposed to contaminating effects of patients and/or operators, the method comprising:

• during a utilization phase for an examination procedure of a patient,
• acquiring sensor data of a sensor arrangement detecting at least a portion of the usable surface, wherein the sensor arrangement comprises at least one 3D camera and/or at least one microphone, wherein at least one of the at least one cameras is an infrared camera, and instances of contact are detected on the basis of a temperature difference of a current image from at least one previously acquired image on completion of its cleaning phase, and wherein a comparison image comprises temperature information;
• and
• determining, by evaluation of the sensor data, a surface map having potentially contaminated regions of the usable surface, wherein for the determination of the surface map during the utilization phase by an image processing algorithm, which evaluates the sensor data of the 3D camera, instances of contact with the usable surface made by a current patient and/or a current operator and/or aerosol generating procedures related to respiration processes are detected, wherein contacted regions of the usable surface and/or regions affected by the aerosol generating procedures are marked as contaminated regions, wherein in addition to instances of contact, presence of bodily fluids on the usable surface is detected using the temperature difference, and wherein regions of the usable surface having bodily fluids are also marked as contaminated;
• and
• during a cleaning phase following the utilization phase,
• outputting cleaning information of the potentially contaminated regions to a cleaner;
• and/or
• using the cleaning information of the potentially contaminated regions for actuation of at least one cleaning apparatus of the imaging facility for targeted cleaning of the potentially contaminated regions.

• and
• wherein without the presence of people and additional objects in a field of view of the at least one camera, together with the comparison image, acquiring a geometry reference image, which describes a three-dimensional geometry comprising a three-dimensional course of the usable surface, wherein by forming difference images of the geometry reference image with at least one currently acquired image, the people and/or objects obscuring the usable surface are detected and taken into account when determining contaminated regions;
• and
• during a cleaning phase following the utilization phase,
• outputting cleaning information of the potentially contaminated regions to a cleaner;
• and/or
• using the cleaning information of the potentially contaminated regions for actuation of at least one cleaning apparatus of the imaging facility for targeted cleaning of the potentially contaminated regions.
