Radiation: Applications

2.1K
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...

Area of Science:

  • Radiation Oncology
  • Medical Physics
  • Patient Care

Background:

  • Historically explored, upright radiotherapy is gaining traction for stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT).
  • Conventional supine/prone positioning has limitations, particularly for certain patient groups.

Purpose of the Study:

  • To explore the technological advancements, clinical implications, and adoption steps for upright radiotherapy.
  • To highlight the potential of upright SRS/SBRT to improve patient comfort, accessibility, and treatment efficacy.

Main Methods:

  • Review of technological advancements in patient simulation, immobilization, image guidance, and treatment planning for upright delivery.
  • Assessment of recent developments in upright imaging systems and specialized positioning equipment.
  • Analysis of studies demonstrating accuracy and feasibility of upright SRS/SBRT.

Main Results:

  • Technological progress in imaging, immobilization, and planning supports safe and effective upright SRS/SBRT.
  • Upright positioning achieves sub-millimeter accuracy comparable to supine techniques.
  • Economic benefits include reduced infrastructure costs and potential for compact centers.

Conclusions:

  • Upright radiotherapy, supported by technological innovation, is a viable and potentially advantageous approach for SRS/SBRT.
  • Addressing imaging system limitations and further research will facilitate widespread adoption.
  • Upright SRS/SBRT can expand treatment accessibility while maintaining high precision and efficacy.
