The Food and Drug Administration has cleared Bio-Scan’s digital IRIS (Interactive Radiotherapy Imaging System) for use in radiation therapy. IRIS is a portal imager for patient-positioning control during treatment.
IRIS uses an amorphous silicon flat-panel detector. The Geneva, Switzerland-based vendor said the detector will be available in two sizes, 20 x 20 cm and 41 x 41 cm. Also available is a viewing console, IRIS-View, which interfaces with a standard PC using a Microsoft Windows operating system and a standard color monitor.

![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)
