Med Physics

Medical physicists are integral part in radiotherapy team.
We perform following function


  • Absolute dose measurement for tele cobalt and Linac low and high energy photons and electron beams
  • Generation of beam data ( PDD,TMR,OUT PUT ,TPR ,WEDGE FACTORS ) for calculations and transfer to Eclipse treatment planning system .
  • Relative dosimetry checks in water phantom and solid phantom.
  • Weekly out put checks and energy constancy checks. Chamber constancy checksPostal dose audit of cobalt and Linac beams using TLD from IAEA.
  • Routine quality assurances of Cobalt, Linac, simulator and HDR Brachytherapy Varisource machine.
  • Manual simulator based planning and Calculations, and 3D CT based conformal radiotherapy planning, dose volume histogram, plan transfer to Varis and first day treatment set up, verifications and portal vision.
  • Preparation for IMRT physical data . Brach therapy ICR, Intraluminal, interstitial planning, dosimetry and treatment.
  • Radiation protection, safety survey and safety of staff, patents and general public. Personnel monitoring of radiation workers in hospital using TLD badges.
  • Participation in academic activities.
