b. Preserve surrounding tissue function

c. Eradicate the malignancy

d. Prolong side effects as tissue recovers

Prolong side effects as tissue recovers

Radiotherapy treatments:

Are treated us prescriptions, Require a physicians order, and start with a consultant

The radiotherapy prescription includes

1. treatment field angles

2. protraction period

3. radiotherapist designated to deliver treatments

4. total dose administered

5. fractionalized dosages

6. patient's mental altitude

7. treatment techniques

8. treatment fields and dimensions

9. patient side effects

1, 2, 4, 5, 7, and 8

Radiotherapy treatment plans require

an informed consent

The treatment planning process is typically completed

using a simulator

Palliative treatment plans

require fewer treatment sessions than curative plans.

PET/CTs are considered:

a. Hybrid machines

b. Essential to fusion imaging

c. Integral to treatment planning and staging

d. All of the above

All of the above

Radiotherapy treatment plans

are prescribed by a radiation oncologist

Radiotherapy treatment plans

are carried out by the radiotherapists

X-rays used for radiotherapy

are in the MegaVoltage range of energies

When radiographic images are produced during portal imaging using megavoltages,

Compton interactions predominate and very low contrast images are produced

Linear accelerators are capable of:

a. 360-degree rotation.

b. x-ray and electron therapy.

c. measuring dose rate in real time.

d. all of the above

All of the above

Proton radiotherapy is particularly beneficial because of:

a. protons depositing their total energy within the target tissue.

b. the positive charge of protons.

c. the minimal scatter radiation produced with protons.

d. all of the above

All of the above

This most common therapy unit is the:

Linear accelerator

The invention of the _____________ tube allowed for high voltage ranges and pentration of tissues possible?

Coolidge

What are the two goals of the treatment planning simulator?

Accuracy and reproducibility

What is the difference between pallative and curative?

Curative treatment is used with the intention to cure the disease in question. Pallative is used to either shrink the disease or ease some pain the patient may be going through. Due to the fact that pallative is not used to treat the disease, it will require less treatment sessions than a curative treatment plan would.
