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...

Response Surface Methodology

Response Surface Methodology

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Area of Science:

Medical Physics
Radiation Oncology

Background:

Historically, radiation oncology dose-outcome studies lacked spatial information, relying on dose-volume histograms.
Dose-surface maps (DSMs) are gaining traction for analyzing spatial dose distributions and identifying radiosensitive regions.
Limited adoption of DSMs is attributed to methodological variations and a lack of open-source code sharing.

Approach:

Developed rtdsm, an open-source software for calculating DSMs from DICOM data.
Incorporated user-customizable features for DSM calculation and analysis.
Included core functionalities such as DSM calculation, equivalent dose conversions, feature extraction, and accumulation.

Key Points:

rtdsm facilitates DSM calculation and analysis, improving reproducibility.
Implemented and demonstrated both planar and noncoplanar DSM slicing methods.
Showcased use cases for equivalent dose conversion and DSM feature extraction for treatment comparisons.

Conclusions:

rtdsm is a standalone, open-source software providing essential DSM-based study functionalities.
Freely accessible on Github to promote collaboration and community use in medical physics and radiation oncology.
Aims to increase access to and reproducibility of DSM-based research.
