J2 Medical of Pittsburgh has released an upgrade to its Akucal calibration tool.
Akucal Evolution features a solid Rollee marker, as well as Ball Claw, a removable marker holder that allows users to sanitize and autoclave. It also includes new comolded lead figures that reference the marker size in every image, according to J2.
Next month, the company plans to release a flexible image receptor holder that can hold both computed radiography cassettes and digital radiography panels. Gymie-R clamps to the table to hold cassettes of various sizes; it allows users to take images on the table, beside it, or under it, the company said.

![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)
