Carestream Health has delivered digital radiography (DR) systems to Indiana University Health Bloomington Hospital in Bloomington, IN.

The hospital installed two DRX-Revolution mobile x-ray systems with DRX-1C detectors to provide portable exams for patients in all areas of its 250-bed facility, according to Carestream. The hospital performs up to 1,200 portable x-ray exams each month, Carestream said.

(c) Training data is generated through manually labeling using SLEAP’s graphical user interface. (d-e) Neural network detection schematic. For each quadrant a series of two networks were used. The first identifies the quadrant center, the second using input of the first, then identifies individual anatomical landmarks within a quadrant. (d) Four neural networks were trained, each with the objective of identifying a chest quadrant centroid. The four separate quadrants are visualized as colored boxes (right upper quadrant, green; right lower quadrant, blue; left upper quadrant, red; left lower quadrant, yellow). (e) Serial centroid then anatomical identification. Two quadrant examples showing confidence maps of trained neural networks identifying quadrant centroids (left) and then anatomical confidence maps (right).

It is worth noting the confusion of a consolidation with mammary tissue and of two nodules with the two mammary areolae. Image courtesy of Scientific Reports.
