Measurement and calculated dose in breast phantom
The aim of this study was to compare the dose calculated by NUCLETRON PLATO treatment planning computer with thermoluminescence dosimeter (TLD) measurement in breast cancer radiotherapy. The absorbed dose distribution for one-field technique and two-field techniques were discussed. The study was...

| description |
The aim of this study was to compare the dose calculated by NUCLETRON
PLATO treatment planning computer with thermoluminescence dosimeter (TLD)
measurement in breast cancer radiotherapy. The absorbed dose distribution for
one-field technique and two-field techniques were discussed. The study was
done by comparing interest point dose values calculated by treatment planning
computer with dose values measured by LiF TLDs. Utilizing an anthropomorphic
phantom, TLDs were placed inside a breast phantom and were irradiated with
6MV SIEMENS MEVATRON linear accelerator. One-field technique and two-field
techniques were used for the irradiation. Readings from irradiated TLDs were
analyzed. Absorbed dose distributions for one-field and two-field techniques were
obtained from the computer. Based on the results, dose values for the four points
of interest in which calculated by the treatment planning computer and measured
by TLDs were within 13%. Inexact location of points of measurement during
phantom's set up caused large deviation between the calculation and TLD
measurement. TLD measurement and the calculation do not comply to ICRU
recommendation. |
