TI  - The daily reproducibility of large, complex-shaped radiotherapy fields to the 
      thorax and neck.
PG  - 39-41
AB  - A series of patients treated with complex fields to the thorax and neck utilising 
      individually tailored shielding blocks made from low-melting-point alloy (LMPA), 
      were investigated using treatment verification film to identify field placement 
      errors. A total of 19 patients yielded 171 machine verification films, which were 
      analysed. It was found that on 21% of occasions the intended treatment volume was 
      partially shielded, by more than 1 cm, by the lead blocks prescribed to protect 
      the lungs. On half of these occasions (11% of the total), the areas erroneously 
      shielded contained known disease. Suggestions are made for minimising such errors 
      in the future.
