Several departments can share a device while competing for the same few supported sessions. A booking calendar filled with requests may give the impression of high utilisation, yet late preparation, staffing gaps or overruns can prevent planned activity. The infrastructure decision should examine the complete scheduled service before adding another unit or extending the advertised opening hours.
Define the supported appointment
The planning team should identify the room, qualified personnel, preparation and support required for its intended imaging service. Clinical decisions and examination protocols remain with the appropriate professionals. The calendar should reserve the resources that must coincide, rather than represent equipment time alone. WHO's device-management guidance connects technology with appropriate use; the editorial implication is that a nominally available machine cannot create an appointment without the rest of the service. A shared schedule should make those dependencies clear before requests are confirmed.
Booking rules should also state when unconfirmed requests release their reserved time. Holding capacity indefinitely for uncertain work can make demand appear stronger while preventing another department from arranging an appointment that its full team could support.
Find the source of repeated lost slots
Imagine a hypothetical facility where several appointments are cancelled because a necessary staff member is assigned elsewhere at the same time. The device appears underused even while demand is high. Another machine would not resolve that conflict. The review should distinguish patient absence, preparation issues, staffing, equipment interruption and scheduling changes. Different causes require different actions. A generic utilisation percentage can hide the operational evidence needed to decide whether longer sessions, different bookings or additional capability would improve access.
Agree priority without private calendars
Departments need an approved process for allocating shared capacity and handling urgent changes. Informal reservations can leave the central calendar inaccurate, leading to apparent shortages and double commitments. The schedule should record changes and the work displaced, with authority that users understand. Staff should also know how unused capacity becomes available to others. The institution's qualified leaders must define how service needs and urgency determine the order in which patients are scheduled, preserving professional responsibility within the shared calendar.
Approve expansion against a service model
A proposal for another device should state which constraint it removes and which additional staffing, rooms and support it requires. The comparison should include the existing service's recoverable capacity, with realistic limits on what scheduling improvements can achieve. Maintenance and fallback arrangements remain part of the model. Management can then evaluate an expansion through completed, supported activity rather than bookings alone. A shared service works when its users can see what is available, why priorities change and which investment would enable more dependable delivery across the departments relying on it.
