Figure 3. Dose profile along the longitudinal axis of the small neonate phantom (10 cm long) from six thermoluminescence dosimeter positions (five positions at 3 cm depth). Data is given for Techniques 1 and 2 at 54 kVp. Dotted line delineates centre of single field. Region of field overlap for Technique 1 (limits of 10 cm x 10 cm fields) is also shown.
