The FDA has given 510(k) clearance for Marconi Medical Systems to market its latest version of the Acqsim CT simulation scanner with a larger bore and a larger field-of-view.
The Acqsim scanner has an 85-cm bore, compared with 70 cm for earlier versions. It also features a 60-cm display field-of-view, up from 48 cm, along with laser positioning lights and oncology-specific scanner protocols and controls.
Marconi says the new scanner simplifies treatment planning for difficult cases such as breast tumors, Hodgkins lymphoma, and large patients. The company said it has more than 50 customers interested in the simulator.
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.
