Radiotherapy CR debuts
Orex Computed Radiography has developed a CR system optimized for use in radiotherapy. The Orex CR.RT captures megavoltage portal images for treatment verification as well as kilovoltage images for treatment simulation. Conventional portal cassettes
Orex Computed Radiography has developed a CR system optimized for use in radiotherapy. The Orex CR.RT captures megavoltage portal images for treatment verification as well as kilovoltage images for treatment simulation. Conventional portal cassettes cannot stand up to the high doses applied during radiotherapy, according to the company, requiring a technician to enter the room and replace the cassette at some point during delivery of the treatment. The Orex poRT CR cassette can remain in position for the duration of the treatment. The low-cost, compact new CR, which features an autoloading cassette, comes with a CR laser scanner, diagnostic cassettes for use with treatment simulators, portal cassettes for use with linear accelerators and cobalt-60 units, reusable phosphor plates, RT software, and PC-based review stations.
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.
