1. A computer-implemented method to correct shadow regions in a current scan of a patient; the method comprising: receiving biomedical imaging data and patient demographic, data corresponding to the current scan of a patient; checking the biomedical imaging data in real-time to determine if an artery of the patient has a calcium deposit in a proximal wall of the artery; acquiring arterial data of the patient as a combination of longitudinal B-mode and transverse B-mode data; using a data processor to automatically recognize the artery in a distal wall; using the data processor to calibrate a region of interest around the automatically recognized artery using edge flow, the region of interest being automatically calibrated; determining, automatically, the intima-media thickness (IMT) of an arterial wall of the automatically recognized artery; and using the data processor to correct the IMT in the shadow regions in longitudinal B-mode ultrasound images by use of information from transverse B-mode ultrasound images.
