Varian to start shipping LAST units
Varian Associates of Palo Alto, CA, plans to begin commercial shipments in June of its VIP-9-QR/1 digital fluoroscopy detector, which is based on the company's Large Area Sensing Technology (LAST) amorphous silicon digital detector. The company's Varian
Varian Associates of Palo Alto, CA, plans to begin commercial shipments in June of its VIP-9-QR/1 digital fluoroscopy detector, which is based on the company's Large Area Sensing Technology (LAST) amorphous silicon digital detector. The company's Varian Imaging Products subsidiary is supplying the detectors to OEMs for incorporation into complete fluoroscopy systems.
The VIP-9 detector is designed to replace image intensifier tubes in fluoroscopy systems. Image intensifiers are bulky and weigh up to 100 lb, which compares with a weight of about 15 lb for the Varian receptors. Picker International, for example, is using a Varian detector in its Venue interventional CT/x-ray suite to create more room for healthcare personnel working near patients (see story, page 3). In addition to fluoroscopy, VIP-9 supports digital radiography, and can also be used for nonmedical applications, such as nondestructive testing.
The VIP-9 detectors have not yet been cleared by the Food and Drug Administration and thus are limited to investigational use in medical applications. Varian will sell the detectors to OEMs at a list price of $98,000.
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.
