3-D Ultrasound Vascularity Assessment for Breast Cancer Diagnosis
Abstract
Several developments were undertaken to improve ultrasound imaging for breast cancer diagnosis and management. Techniques to align and reshape 3-D ultrasound image volumes were explored using MIAMI Fuse(Trademark) software to display 3-D studies of the breast to make subtle image features and changes over time more easily detected, evaluated and quantified. Applications studied included: (1) creation of composites from volumes acquired from differing viewpoints; and (2) combination of multiple, slightly-overlapping 3-D image volumes to allow display of large-scale breast architecture as well as large masses and their change. Measurement of scan head motion based on the rate of changes in images resulted in initial commercial implementation of simple 3D imaging in real time. Software was also developed to enable researchers to better study mapping of lactic ducts in 3D ultrasound. Further, this project also contributed to a larger clinical study of quantitative vascularity as a discriminator between benign and malignant breast masses. Recently, an ultrasound breast vascularity measure was found to be as good as subjective evaluation of nonvascular structures, and the combination of the vascularity and a scale measures were very promising.
