How to draw isodose curve from the MCNP program?
What is an isodose curve?
An isodose diagram for a given beam consists of a family of isodose curves, usually plotted with an increasing depth dose percentage. It shows the change in dose as a function of depth and distance from the central axis.
Isodose diagrams are used in radiation therapy to represent the dose distribution within a given volume. These diagrams consist of isodose curves, which are lines that connect points receiving the same dose of radiation. Here's a brief overview:
Key Points
-
Definition: Isodose curves represent levels of absorbed dose similar to isotherms representing temperature.
-
Purpose: They help visualize the dose distribution within a patient or phantom, ensuring that the target area receives the prescribed dose while minimizing exposure to surrounding healthy tissues.
-
Representation: Curves are typically drawn at regular intervals of absorbed dose (e.g., 100%, 90%, 80%, etc.).
-
Applications: Used in treatment planning to optimize radiation delivery and verify that the treatment plan meets the desired dose distribution
