An analysis of breast motion using high-frequency, dense surface points captured by an optical sensor during radiotherapy treatment delivery

This multidisciplinary paper reports the first clinical test of an optical measurement system which was developed as part of an EPSRC funded project (EP/D077702/1). The instrument in question, developed entirely within the submitted unit, provided the medical physics and clinical teams with unique insights into patient breast movement, during delivery of radiotherapy, at resolution levels unprecedented in both space and time. The data provided facilitated the first determination and study of clinically important parameters such as: detailed 4D (x,y,z&t) movement patterns in the breast, links to breathing and even phase relationships between movements in different parts of the breast.
