Hologic has introduced Explorer, an entry-level fan-beam bone densitometry system. Explorer combines Hologic’s OnePass fan-beam technology and internal reference system with complete procedure automation, according to the Bedford, MA-based vendor.
Using a multidetector array, Explorer acquires a two-dimensional x-ray image with a single-detector pass along the patient’s length, the company said. The system offers conventional spine, hip, and whole-body density measurements, international language support, and productivity tools, according to the vendor.
An Express Exam feature automates scan and analysis workflow, and can be combined with the firm’s IRIS connectivity suite. Hologic showcased Explorer at the annual Journées Françaises de Radiologie (JFR) 2003 meeting in Paris. Commercial availability of the system is subject to regulatory approvals, including from the Food and Drug Administration.

![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)
