IVB 1000 Well Chamber

Global standard for independently verifying prescribed brachytherapy patient dose.

Tailored for Calibration of Long Source Trains

The IVB 1000 Well Chamber is similar to the HDR 1000 Plus but has an active length which is four times longer, making it ideal for long source trains.

Why Perform Independent Verification?

  • AAPM TG-56, TG-40 and TRS-398 recommend independent verification of source strengths.
  • Without independent calibration, centers in the U.S. may be forgoing reimbursement income.
