Lumisys has released version 4.0 of its DI-2000 acquisition and viewing software, which is included with the vendor’s Lumiscan film digitizers and ACR-2000 low-cost computed radiography system.
In version 4.0, the DICOM-compliant and Windows NT-based DI-2000 software includes advanced image processing algorithms that respond to anatomical characteristics, according to the Sunnyvale, CA-based firm. General image quality is improved by applying edge enhancement and more flexible contrast control. By improving contrast, Lumisys believes that its selective contrast enhancement capability further enables users to visualize particular anatomical details.
In other 4.0 improvements, image acquisition and review requires fewer steps than in previous versions. In addition, a "group send" capability routes a single image to multiple destinations, while a "speed send" feature allows users to send images from the image review window. An automatic window/level control has been added to further enhance user productivity, automatically adjusting images to optimum settings, according to Lumisys.

![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.
