Estimate radiology suite patient capacity with inputs that match day-to-day radiology suite operations. The calculator keeps workload, available capacity, and operational assumptions visible, so you can test a baseline and then change one driver at a time. Results are planning estimates: use locally observed rates and apply clinical, labor, safety, and scheduling requirements before making an operational decision.
Theoretical capacity = active units × patients per unit-hour × operating hours
Practical capacity = theoretical capacity × operational efficiency
Practical capacity discounts the mathematical maximum for ordinary downtime, coordination, setup, and workflow friction.
Planning estimate only. Validate assumptions against local policy, staffing rules, equipment constraints, case mix, and patient-safety requirements.
3 active units at 2.5 patients per unit-hour for 11 hours provide 82.5 theoretical slots.
82.5 × 0.80 = 66 patients
No. It is an operational estimate based on average throughput, hours, active units, and an efficiency adjustment.
Use the efficiency input for routine downtime, or reduce active units and operating hours for known outages.
Use a sustainable observed rate from comparable cases rather than a short-term technical maximum.
Only when their patient-hour rates are reasonably comparable. Otherwise calculate each type separately and add the capacities.
The efficiency factor accounts for setup, coordination, cleaning, interruptions, and other normal workflow losses.
