Manually selected skin (a) and rib (b) maximal point doses for a Contura® plan after a comprehensive review of 3D planning CT images.

(a) One hundred manually measured OARs (skin and rib) maximal point doses (, ordinate) compared with the true (reference value) maximal dose (, abscissa) extracted from dose volume histogram data. The straight solid line represents the ideal case where equals . The data were presented for four different groups: manual maximal skin (circle) and rib (square) point doses for 25 MammoSite® patients; manual maximal skin (triangle) and rib (star) point doses for 25 Contura® patients. (b) Schematic diagram for three different cases in manual measurement method: a manually selected dose point is located exactly on the surface of skin (case B); off the skin surface either toward the balloon (case C) or in a direction away from the balloon (case A).

Tables

Generic image for table
TABLE I.

Skin and rib maximal dose relative to the prescribed dose (34 Gy) for 50 balloon-based HDR brachytherapy patients (25 MammoSite® and 25 Contura®); for each patient, two data points (maximal skin and rib dose) were acquired and the total number of data was 100. The absolute and relative maximal dose differences between the manual selection method and the objective method.

Generic image for table
TABLE II.

Comparison of the absolute and relative maximal dose differences between two different groups of data presented in Table I.
