摘要：
Methods and systems for imaging calcium in a subject are provided. In one aspect a method for imaging one or more micron-sized calcium deposits in a tissue of a subject can include delivering a transmission ultrasound wave field from a transmission transducer array to a body part of a subject, receiving transmission data from the transmission ultrasound wave field at a transmission receiver array, delivering a reflection ultrasound wave field from a reflection transducer array to the body part of the subject, receiving reflection data from the reflection ultrasound wave field at a reflection receiver array, generating speed of sound data from the transmission data, and refraction correcting the reflection data using the speed of sound data to generate a corrected reflection image showing a micron-sized calcium deposit image.
