Connectivity to MOSAIQ® OIS

Confidence for you and your patients

  • Contributes to paperless brachytherapy workflow information
  • Automated scheduling and billing process
  • Documented dose and structure sets
  • Automatically exchange breast cancer treatment plans created with Oncentra Brachy and treatment records generated by the afterloader
  • Perform dose tracking based on the treatment plan and treatment record for the selected and verified patient
  • Provide a more efficient and electronic way to capture information that will be included in the patient's Continuity of Care Document (CCD), data as required for meaningful use (Stage 1 and beyond)

OncoSmart catheter system

A full package for accelerated partial breast irradiation (APBI). Elekta offers a range of brachytherapy options to treat breast cancer cells. The combination of the OncoSmart Catheter System and the Breast CT/MR Template Sets offers excellent breast cancer treatment options.

OncoSmart catheter system

“The applicator enables the user to create large volume breast implants. The adjustable template has an integrated guiding template, which ensures the exact placement of needles and flexible implants or OncoSmart catheters. Also, the single large template has a special hole geometry. This applicator allows for excellent coverage of the target volume and optimized conformity with the patient's anatomy.”

Oncentra Brachy

Comprehensive treatment planning software

Designing the optimal dose distribution can be a time-consuming job. The latest version of Oncentra Brachy offers a series of useful tools that simplify many repetitive tasks, such as contouring and reconstruction. Oncentra Brachy buys you time to focus on what counts: creating the optimal dose distribution.

Oncentra Brachy also helps you optimize breast cancer treatment plan accuracy, providing easy navigation to any plane that offers the most relevant information per region of interest.

Reduce implant reconstruction time

  • Instant applicator reconstruction in relation to anatomy
  • Contains the complete geometry of Elekta's gynecological applicators
  • Includes the measured source paths of ring applicators
  • Accounts for dose attenuation resulting from shielding during planning and shields are fully visible

Dose distribution calculated by ACE

  • Algorithm based on the TG-186 recommendations published by the AAPM workgroup in 2012
  • Discriminates between tissue, air and bone
  • Accounts for tissue heterogeneities, lack of backscatter from areas with no tissue, applicator attenuation and shielding

Implant modeling tool

  • Reconstruct multicatheter implants immediately
  • Drag & Drop 3D applicator geometry for accurate and fast reconstruction
  • Extra Coordinate System (ECS) allows quick and easy navigation to the correct plane views

Automatic dose optimization


  • Paired with the Dwell Time Deviation Constraint (DTDC)
  • Limits high variation in dwell times


  • Improves plan optimization with Dwell Time Gradient Restriction (DTGR)
  • Control high and low peaks in dwell times
  • Focus optimization where it is needed with needle locking

Radiation therapy treatment delivery

Safe, simple, intuitive brachytherapy workflow

View Brochure

Five simple features are the basis for the Flexitron way of working, introducing a new standard in treatment delivery

  • Standardized transfer lengths, less prone to human errors during reconstruction as there is only one indexer length.
  • Reference zero at entrance of applicator, no need to measure the distal tip.
  • Metric dwell position numbering, 1 mm step size in a treatment window of 400 mm.
  • Forward stepping results in a reproducible source positioning within 0,5mm accuracy
  • Intuitive user interface, smooth navigation saves time.

Why Flexitron?

  • Simple quality assurance
  • 40-channel option for large implants
  • Connected to major oncology systems such as MOSAIQ®
  • Safe investment with future upgrade potential
  • Available in either Iridium-192 or Cobalt-60*

* Not available in all countries.
