Computer-aided simple triage (CAST) are computerized methods or systems that assist physicians in initial interpretation and classification of medical images.
CAST software systems perform a fully automatic initial triage (classification) of diagnostic medical imaging studies.
CAST is primarily intended for emergency diagnostic imaging, where a prompt diagnosis of critical, life-threatening condition is required.
Unlike traditional CAD, mainly used to detect malignant lesions, CAST deals with acute, life-threatening conditions, when a prompt diagnosis is time critical.
The clinical benefit is achieved: Traditional CAD system usually plays the role of a "second reader" and is used after or during the interpretation performed by physician.
Since CAST operates in a fully automatic mode, it should be able to deal with any study, regardless of image quality, patient anatomy, etc.
