A method to improve the accuracy of ultrasound geometrical measurements of boundaries in soft tissue

The geometric distortion due to the neglect of refraction in existing ultrasound scanners is demonstrated. An iterative technique to correct for refraction errors in B-mode ultrasound, denoted Second Order Refraction Transposition (SORT), is presented. In vitro experiments were performed that confir...

Zusammenfassung:The geometric distortion due to the neglect of refraction in existing ultrasound scanners is demonstrated. An iterative technique to correct for refraction errors in B-mode ultrasound, denoted Second Order Refraction Transposition (SORT), is presented. In vitro experiments were performed that confirm the calculated results.
