From: Optimizing integrated imaging service delivery by tier in low-resource health systems
Recommended ultrasound imaging strategy by health system tier. Higher levels on the pyramid denote increasing complexity. For each tier, red indicates a requirement for higher specialization of service (technology and personnel), while blue indicates lower specialization requirements (POCUS = Point of Care ultrasound; NR/S-US = non-radiologist/non-specialist ultrasound; complex R/S-US = radiologist/specialist ultrasound)
