Q

is a clinical modality that deals with the use of ionizing radiation, in the treatment of patient with malignant (occasional non-malignant) neoplasms. The aim of radiotherapy is to delivery a precise dose of radiation to a defined tumor volume with a minimal damage as possible to the surrounding healthy tissues.

Q
  • The dose that can be tolerated by the normal tissue in the treatment zone varies with the total time over which the dose is given.
  • For a given volume, the size of each fraction dose and the time interval between fraction alters the biological effect.
  • The higher the fraction dose (Dose Rate) the greater the damage potential.
  • Missed treatment may lead to an overall treatment period which significantly longer than intended.
A

DOSE RATE / DOSE PER FRACTION / FRACTION DOSE

17
Q

TARGET VOLUME / VOLUME IRRADIATED

A
  • GROSS TUMOR VOLUME (GTV)
  • CLINICAL TARGET VOLUME (CTV)
  • PLANNING TARGET VOLUME (PTV)
18
Q

Is the gross palpable or visible/demonstrable extent location of malignant growth. Corresponds to the parts of the tumor in which the tumor density is greatest.

A

GROSS TUMOR VOLUME (GTV)

19
Q

Volume that contains a demonstrable GTV and subclinical microscopic malignant disease that must be eliminated.

A

CLINICAL TARGET VOLUME (CTV)

20
Q

Contains the tissues to be irradiated with specified time dose pattern. This volume consist of a tumor and adjacent tissue in which tumor is presumed to be present, in some instances also the regional lymph nodes.

A

PLANNING TARGET VOLUME (PTV)

21
Q

CLINICAL METHODS OF TREATMENT

A

PROTRACTION/FRACTIONATION

22
Q

The dose is delivered continuously but at a lower dose rate, it is much less effective because of lower dose rate and longer irradiation time.

A

PROTRACTION

23
Q

The administration of a course of radiation treatment in a planned series of fractions of total dose

A

Fractionation

24
Q

The administration of a course of radiation treatment in a planned series of fractions of total dose
