4D Brachytherapy™ offers prostate cancer patients all the benefits of a stranded implant but the accuracy and flexibility of a real-time procedure in a time efficient manner.


Find out more about 4D Brachytherapy™ by viewing the video below.

4D Brachytherapy™ is a one-stage implant technique using a combination of pre-loaded stranded seeds around the periphery of the prostate gland and seeds optimally placed within the centre. From a simple clinic-based scan, a web-based nomogram allows the calculation of the number of stranded and central seeds required for the procedure.


Using this novel combination technique the procedure can normally be performed within 45 minutes. Improved dosimetry and clinical outcomes together with reduced side effects have been demonstrated over traditional two-stage approaches.


4D Brachytherapy™ benefits:


  • Real-time technique utilising stranded seeds around the periphery to optimise the dose

  • Time efficient, taking approximately 45 minutes in theatre

  • Avoids the risk of seed migration to the chest by using stranded seeds

  • Minimised pre-operative physics preparation and planning

  • Utilises a library of web-based nomograms

  • Central seeds are implanted in the centre of the gland to optimise dosimetry

  • webBXT, our web-based online seed ordering platform, minimises physics time

  • By reducing the time to perform the implant it improves efficiency and reduces potential complications

  • It avoids the risk of seed migration using stranded seeds peripherally yet maximises radiation coverage

  • Using optimally placed seeds at the apex of the gland it reduces radiation dose to the bulb of the penis and membranous urethra, so reducing morbidity

  • A more intuitive technique not relying on coordinates but implanting the prostate in an easily learnable technique
