From: Optimizing integrated imaging service delivery by tier in low-resource health systems
Recommended imaging workforce/human resource strategy by health system tier. Higher levels on the pyramid denote increasing complexity and requirement for specialization of staff. Green denotes a requirement for higher-level specialization or even sub-specialization (e.g., neurointerventional radiology, oncologic imaging), while blue denotes lower-level specialization. Technologists / radiographers are required at all tiers above primary care centers and may also have a role and primary care level even though not essential (NR = Non-Radiology; technologists = radiographic technologists, radiographers, sonographers)
