What is Radiation Treatment?
 
 
 
Advantages of  Linear Accelerator OVER COBELT    

 

S. No. Linear Accelerator Cobalt
1
Multiple Energies
Low Energy and Single Energy
2
Able to Treat Depth
Unable to reach  Deeper Tissues
3
Skin Sparing Effect therefore less Skin Toxicity
More Skin dose leading to more Normal / Critical Structure side Effect
4
Less Penumbra therefore less Normal Tissue side Effects
More Penumbra therefore More Normal / Critical Structure side Effect
5
Shielding Via Multileaf Collimator (MLC) – More Accurate; More Precise
Shielding of Normal Tissues by External Blocks – Crude and less Accurate
6
Simulation is 3 Dimensional
Simulation in 2 Dimensional
7
Field matching Easier Because of Independent Asymmetric Jaws
Field Matching is Difficult
8
Latest Techniques like 3DCRT / IMRT / IGRT Possible
Advance Techniques Not Possible
9
Treatment Verification Via Online Portal Imaging (2D or Cone Beam CT)
Treatment Verification Not Possible
10
Able to deliver High Doses to the Tumor with Minimum Doses to the Normal Tissues therefore Increasing Chance of Cure.
Escalation of Doses Difficult without Damaging Normal Tissues
11
More Radiology Safety
Possibly of Radiation Leakage
