A cohort of 30 consecutive locally advanced cervical cancer (LACC) patients, whose both the 2-D orthogonal X-Ray images on a conventional simulator and 3-D volumteric images on a CT simulator were simultaneously obtained during each HDR-ICB fraction.

Data pertains to a prospective cohort study to find correlation between the doses to the traditional ICRU points and contemporary 2cc volumes of the rectum and bladder in HDR brachytherapy for cervical cancer. Out of total 118 ICB fractions administered to these patients the data pertaining to 12 fractions is excluded. The reason for exclusion is that CT simulation images could not be acquired due to logistic issues for 11 fractions and for 1 fraction 2-D data could not be retrieved.
