The U.S. Food and Drug Administration (FDA) has cleared the Multix Impact C ceiling-mounted digital radiography (DR) system from Siemens Healthineers. The FDA also cleared Multix Impact VA20, a new version of the company's existing floor-mounted DR system.

Image courtesy of Siemens.Both Multix Impact C and Multix Impact VA20 employ a similar operating system, wireless digital detectors, motorized tube heads, and free-floating tabletop. Siemens is touting the touchscreen user interface on the x-ray tube head, which enables radiologic technologists to remain at the patient's side for longer periods. Patients can also be monitored with the system's myExam 2D camera.
Siemens introduced both systems at the RSNA 2020 meeting.
![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&dpr=2&fit=crop&h=167&q=70&w=250)
