Radiation: Applications

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Radiation Pressure: Problem Solving

Radiation Pressure: Problem Solving

The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

Background:

Intensity-Modulated Radiation Therapy (IMRT) uses multi-leaf collimators (MLCs) to deliver precise radiation doses.
MLC maximum leaf spread constraints can necessitate splitting large Intensity Maps (IMs) into smaller, overlapping sub-IMs for delivery.
This splitting process impacts treatment efficiency and delivery time.

Purpose of the Study:

To develop a computationally efficient algorithm for the optimal field splitting problem in IMRT.
To minimize the total complexity of sub-IMs generated during field splitting.
To simultaneously minimize the maximum beam-on time for the delivered sub-IMs.

Main Methods:

Formulated the field splitting problem as a shortest path computation in a directed acyclic graph with a Monge property.
Utilized the Monge property to develop a close-to-linear time algorithm for solving the shortest path problem.
Addressed the min-max beam-on time objective by solving a min-max slope path problem in a monotone polygon in linear time.

Main Results:

Developed a close-to-linear time algorithm for optimal field splitting.
The algorithm effectively minimizes the total complexity of sub-IMs.
Experimental results demonstrate fast performance and high-quality splitting on real and generated Intensity Maps.

Conclusions:

The proposed algorithm offers an efficient and effective solution for the optimal field splitting problem in IMRT.
This advancement can lead to improved treatment delivery efficiency and reduced beam-on times.
The underlying shortest path and min-max slope path algorithms may have broader applications.
