Q

what is the radioresponsive phase of a tumor?

A

17
Q

what biological process is essential to radiation cell kill over time?

A

reoxygenation

18
Q

GTV

A

gross tumor volume - seen with naked eye

19
Q

CTV

A
  1. margin on GTV to account for tissue with presumed tumor / typical site of disease spread
  2. assumes no tumor cells outside this volume
20
Q

ITV

A

CTV plus internal margin for physiological movements / error

21
Q

PTV

A

CTV or ITV plus setup margin uncertainty / error

22
Q

what is IGRT?

A

a way to verify with greater precision the tumor’s position to allow for more accurate treatment

23
Q

what are the indications for IGRT?

A
  1. tumors that move

2. tumors abutting critical structures such as spinal cord and brainstem

24
Q

what are the two types of IGRT?

A
  1. stereoscopic / bony

2. cone beam / soft tissue

25
Q

what is stereoscopic / bony IGRT?

A

uses bone structure as template for alignment

26
Q

what is cone beam / soft tissue IGRT?

A

uses a same-day CT for fusion to simulation image
