C-Arm Spec Schema

Frontmatter fields every C-arm system carries on top of the common system fields.

image_intensifier_sizes: [9, 12]        # inches, array (multi-config systems)
generator_power_kw: 15
max_kvp: 120
max_ma_radiographic: 75
max_ma_pulsed: 40
anode_heat_capacity_hu: 300000
anode_cooling_rate_hu_min: 60000
focal_spots_mm: [0.3, 0.6]
resolution_lp_mm: 1.4                   # at largest II field
dqe_percent: 65
software_packages: [GSP, ESP, Vascular, NeuroVascular, Cardiac]
configurations: [Standard-9, Standard-12, Super-C, MD]
motor_driven: false
flat_panel: false                       # vs image intensifier

Rationale

Buyers evaluating refurbished C-arms compare these fields directly. Engineers servicing them rely on kW/kVp/HU to diagnose generator and tube health. Hospitals planning procedure mix need to know which software packages are licensed.
