Shimadzu Medical Systems has installed its first Sonialvision G4 multipurpose radiography/fluoroscopy (R/F) system in the U.S. at Union Hospital in Maryland.
Sonialvision G4 provides a variety of exams from endoscopy and videofluoroscopy for gastrointestinal and swallowing exams to orthopedic and general radiography exams, Shimadzu said. Its high-resolution images are acquired at low radiation doses, according to the company.
Sonialvision's ergonomic design focuses on patient safety and hygiene, accommodating both ambulatory and stretcher- or wheelchair-confined patients, Shimadzu said. The system combines a 17 x 17-inch flat-panel detector with a digital imaging platform, Shimadzu 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.
