[Finite element analysis on the effect of lateral wedge insole intervention on the contact characteristics of the subtalar joint].

Objective: To establish a three-dimensional finite element model of the lower limb bones, and investigate the changes of the contact characteristics of the subtalar joint after using laterally wedge insole intervention.

Methods: Using the reverse modeling technology, the lower limb bones of normal adult volunteers was scanned by CT. Mimics 10.

Simultaneous integrated boost in breast conserving radiotherapy: is replanning necessary following tumor bed change?

Tumor bed (TB) change is often seen during the whole breast irradiation (WBI) in early breast cancer patients. The aims of this study were to evaluate change in seroma volume on repeat CTs and to explore whether replanning is necessary in breast conserving radiotherapy (RT) using the intensity modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB). Thirty patients underwent WBI with 84 CT scans (24 with 3 CTs (CT1, CT2 and CT3) and 6 without CT3) during the 6 weeks of RT were reviewed.
