This study introduces a 4D beta-probe signal for improved intraoperative tumor detection, enabling simultaneous imaging and instrument guidance. This molecular imaging modality enhances minimally invasive cancer surgery by visualizing residual tumor cells.

Area of Science:

  • Medical physics
  • Surgical oncology
  • Nuclear medicine

Background:

  • Minimally invasive tumor resection aims for complete cancer cell removal.
  • Intraoperative nuclear medicine probes aid in detecting residual tumor cells.
  • Current methods lack simultaneous scanning and treatment application.

Purpose of the Study:

  • To extend the 1D signal of a beta-probe to a 4D signal, incorporating spatial information.
  • To develop a system for simultaneous intraoperative molecular imaging and surgical instrument guidance.
  • To enhance the precision of tumor resection in minimally invasive procedures.

Main Methods:

  • Extended a 1D beta-probe signal to a 4D signal, including spatial data.
  • Generated a color-encoded surface map of scanned activity.
