Brachytherapy in cancer cervix: Time to move ahead from point A?

Figure 1 Schematic representation of antero-posterior and lateral radiographs with the applicator for estimation of various applicator components. IUTL: Intrauterine length; VDL: Vertical displacement; ADL: Antero-posterior displacement; ROV: Right ovoid to os; LOV: Left ovoid to os LOV; BP: ICRU bladder point; RP: ICRU rectal point; ICRU: International Commission on Radiation Units and Measurements.
