A new needle-based X-ray system for medical use employs a two-stage X-ray production. Experimental results confirm the system

Area of Science:

  • Medical Physics
  • Radiological Engineering
  • Biomedical Imaging Technology

Background:

  • Conventional X-ray systems have limitations in targeted medical applications.
  • A need exists for compact, adjustable X-ray sources for precise medical interventions.

Purpose of the Study:
