Absolute Dosimetry, Dosimetry Phantoms

Stationary Water Phantom

Completely closed stationary water phantom for high energy photon dosimetry with PTW Farmer chambers

  • Makes it possible to perform quick and reproducible photon calibration measurements
  • Accommodates a PTW Farmer chamber at a fixed measuring depth of 50 mm
  • Beam markers on the top plate
  • Compensates changes of the water volume caused by ambient temperature changes
 
Water Phantom 4322 for Horizontal Beams

Small size water phantom for absolute dosimetry in photon and electron beams with horizontal beam incidence

  • Suitable for calibration of ionization chambers in high-energy photon and electron beams
  • Suitable for monitor calibration in water
  • Makes it possible to irradiate up to three chambers simultaneously
  • Makes it possible to vary the measuring depth from 15 mm up to 250 mm in increments of 5 mm
 
Water Phantom 41001 for Vertical Beams

Small size water phantom for absolute dosimetry in photon and electron beams with vertical beam incidence
  • Suitable for calibration of ionization chambers in high-energy photon and electron beams
  • Suitable for monitor calibration in water
  • Makes it possible to irradiate a thimble chamber in water with vertical beam incidence
  • Makes it possible to vary the measuring depth by water level adjustment
