Three-dimensional radiation dosimetry using polymer gel and solid radiochromic polymer: From basics to clinical applications

Table 5 Comparison of dose quantification techniques

Method	Pros	Cons
MRI	Commonly available at a hospital Easily accessible scan protocol Known accuracy and precision Linear dose response	Low SNR Image artifacts Limited spatial resolution Long scan time
OCT	High spatial resolution Small physical size or compact Easy and free access if owned	Optical artifacts Needs refractive index matching
XCT	Easy access at hospital High SNR Very fast scan	Low image contrast

SNR: Signal-to-noise ratio; MRI: Magnetic resonance imaging; OCT: Optical computer tomography; XCT: X-ray computed tomography.
