| Abstract | Purpose – During the process of needle insertion for interstitial gynecologic brachytherapy, the needles may bend secondary to tissue deflection. Variability in tissue resistance may arise from fat, water, bone or muscle coursed through in the path of the needle. In this work we provide a fast and accurate method to extract and display needles from MR images acquired during MR-guided gynecological cancer brachytherapy. Compared to CT, needle artifacts are less easily identifiable in T2w MR, the sequence of choice for visualizing gynecologic cancer. In previous work [1], we introduced the use of a customized SSFP MR sequence to enhance needle artifacts in these procedures, and in this work we provide a post-processing method that reliably and accurately extracts the needles from images acquired using these SSFP MR images. |
