Figure 5.

Isodose distributions of film‐measured dose (thin lines) and treatment planning system‐calculated dose (thick lines) over a range 2 to 13 Gy, in a plane anterio–lateral to a cervix treatment applicator brachytherapy dose distribution (shown inset), shown left with film flat on scanner plate and right with film naturally curled on scanner plate (in contact with the plate at 0 mm abscissa scale, rising to a maximum 1.5 mm above the scanner plate at maximum of the abscissa scale).
