Healthcare consultancy ECRI Institute has released a new analysis of several surgical C-arms.
The report features tests of two manual systems (OEC Elite CFD by GE Healthcare and Veradius Unity by Philips Healthcare), as well as two motorized systems (Cios Alpha by Siemens Healthineers and Vision RFD 3D by Ziehm Imaging).
The full report, which is available for members at the ECRI website, includes ratings for each model, key specifications, data on hospitals' interest in each of the systems, and the testing protocol.
![Representative example of a 16-year-old male patient with underlying X-linked adrenoleukodystrophy. (A, B) Paired anteroposterior (AP) chest radiograph and dual-energy x-ray absorptiometry (DXA) report shows lumbar spine (L1 through L4) areal bone mineral density (BMD). The DXA report was reformatted for anonymization and improved readability. The patient had low BMD (Z score ≤ −2.0). (C) Model (chest radiography [CXR]–BMD) output shows the predicted raw BMD and Z score in comparison with the DXA reference standard, together with interpretability analyses using Shapley additive explanations (SHAP) and gradient-weighted class activation maps. The patient was classified as having low BMD, consistent with the reference standard. AM = age-matched, DEXA = dual-energy x-ray absorptiometry, RM2 = room 2, SNUH = Seoul National University Hospital, YA = young adult.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/04/ai-children-bone-density.0snnf2EJjr.jpg?auto=format%2Ccompress&fit=crop&h=100&q=70&w=100)
