Triple redundancy marks new PACS controller

A portable, scalable, and fault-tolerant PACS controller was the highlight of an infoRAD exhibit at November's RSNA show. Known as a resilient continuous availability server, RCAS features three identical Unix machines running copies of the same operating system and application software. Its novel design could allow mission-critical image vendors to advertise near 100% availability, according to Brent Lui, who developed the machine at Saint John's Health Center in Santa Monica, CA.
To ensure nearly continuous operation, data transfers are sent to all three machines, which perform special "voting" routines that determine the operational condition of each machine. Operation is then executed step-by-step at the machine with the majority vote. This guarantees that no hardware failure can stop the execution of the operation. In a demonstration at the RSNA meeting, unplugging one of the three servers during image transmission caused less than a two-second interruption.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
