FDA clears Toshiba's Asteion CT scanner
A new CT scanner from Toshiba America Medical Systems has received 510(k) clearance from the Food and Drug Administration. The system, called Asteion, is a subsecond scanner, and Toshiba has positioned it just below the Tustin, CA, vendor's new Aquilion
A new CT scanner from Toshiba America Medical Systems has received 510(k) clearance from the Food and Drug Administration. The system, called Asteion, is a subsecond scanner, and Toshiba has positioned it just below the Tustin, CA, vendor's new Aquilion half-second CT unit (SCAN 9/16/98). Toshiba will introduce Asteion at the upcoming Radiological Society of North America meeting.
Asteion features a 0.75-second rotation speed and solid-state detectors, according to Charles Corogenes, director of the CT business unit at TAMS. The system will carry a 4-million-heat-unit HeliCool x-ray tube and a 48-kW generator. It has a similar graphical user interface to the Aquilion scanner. It will also come standard with Aspire CI, Toshiba's CT fluoroscopy package. Asteion shipments will begin in January, Corogenes said.
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.
