Mould Room


The goal of the mould room rotation is the integration and application, by the second year radiation

therapy student, of the theory and skills utilized in the mould room/machine shop.

If no mounted blocks are being used in this department, student will schedule a visit with personnel

to develop mounted blocks for a “mock or simulated” case.
Accomplishment of this goal will be evaluated by the mould room technicians and the completion

of the following:


a. one custom mounted cerrobend block (from start to finish)

b. one custom electron block

c. bolus (discuss and/or make various depths)

d. compare custom block theory to MLC blocking (parameters, limitations etc.)

Students shall demonstrate:
a. the ability to report on time to the assigned area

b. professional attitudes and respect for staff

c. constructive use of time to complete objectives

d. understanding and application of safety procedures
