Title: Medical Dosimetry


1
Medical Dosimetry
Presented by (Add Hospital name) in conjunction
with The American Association of Medical
Dosimetrists
2
  • We invite you to join us in celebrating National
    Medical Dosimetrists Day by allowing us to
    describe our role in your care.

3
Soyou might be thinking - What is medical
dosimetry?
4
  • Medical Dosimetry, also known as treatment
    planning, is the process where the radiation
    oncologist (doctor) and the medical dosimetrist
    work together to create and calculate your
    treatment plan. This determines where the
    radiation will be targeted while minimizing the
    radiation dose to the surrounding healthy organs
    and tissue.

5
Soyou might be thinking When does this happen?
6
  • This happens behind the scenes after your CT
    Simulation and before the start of your radiation
    treatments.

Treatment Planning
Consultation
CT Simulation
Quality Assurance

Soyou might be thinking How is this done?
8
  • When the CT Simulation is complete, the CT images
    are sent to a special treatment planning
    computer. From the computer, the radiation
    oncologist contours or maps on the CT images the
    target area that will be treated with radiation.

9
  • Occasionally, a diagnostic CT, MRI, or PET scan
    is also used to aid the radiation oncologist with
    visualizing and defining the target area.

  • Prior to developing the plan, the medical
    dosimetrist identifies all organs near the target
    so the doses of radiation to those organs are
    monitored.
  • The radiation oncologist communicates the
    prescription of how much radiation will be needed
    to the medical dosimetrist.

11
Soyou might be thinking How do you know when
my plan is complete?
12
  • The process of creating the optimal plan to
    deliver the prescription dose to the target while
    minimizing the surrounding dose varies from
    patient to patient in treatment plan type and
    complexity.
  • The medical dosimetrist communicates with the
    radiation oncologist to provide the best plan
    based on your medical history and diagnosis.

13
Soyou might be thinking How is my plan
evaluated?
14
  • Many medical dosimetrists began as radiation
    therapists and with additional training have
    specialized in the machine characteristics and
    clinical knowledge to provide the best plan
    possible.
  • Specialized computer systems and tools aid in
    monitoring dose to the target and normal tissue.
    They assist in evaluating how the radiation is
    distributed.
  • The radiation oncologist approves every treatment
    plan prior to the first radiation treatment.
  • Several quality assurance checks are done on each
    treatment plan to verify all parameters are
    correct and ensure patient safety.

15
Sowe are thinking How did we get so fortunate
to be involved in your care plan?
16
  • Thank you and we sincerely wish you the best. It
    is our pleasure to take this journey along side
    each of you.
