Which of the following represents the relationship between the dose and the PDD at a point?

The value of TMR is never greater than:

Calculate the percentage of the dose attenuated if the measured dose with the wedge is 95 cGy and the dose without the wedge is 125 cGy.

In calculating dose to points of interest for isocentric problems, What does SCPD mean?

A patient’s prescription requires a total of 180 cGy to be delivered per day to equally weighted to POP fields (Parallel Opposed Ports).  The treatment time to deliver 100 cGy is 2.15 minutes.  What treatment time must be delivered to each field to follow the prescription?

PDD is dependent on which of the following? I.   Energy II.  Depth III. Field size IV. SSD

A patient is to be treated with 6 MV and a depth of 5 cm.  The linear accelerator is calibrated to 100 SAD.  The patient has a separation of 28 cm.  At midplane, the field size is 14 x 14 cm.  The field size on the patient’s skin is?

The depth of maximum equilibrium is another term for which of the following? 

When using a wedge in the radiation beam, the degree of tilt in the iso dose curve is equal to:

What is the primary communication tool between the radiation oncologist and the treatment planning and delivery team?
