| Popis: | The author describes: (1) a rapid method to produce solid lead shielding blocks with divergent walls to follow the supervoltage beam, which can be ordered from the workshop by a telephonic "blueprint" code; (2) a technique of supervoltage "combined portal filming" to avoid "burn-out" effect of the barium or iodine opacified organs; (3) a quick way to make patterns for irregular lead cut-outs in superficial therapy; and (4) a new moldable tissue density bolus material. |
