Intro Radiation Therapy

Front 1

Antoine-Henri Becquerel

Back 1

discovered that certain elements spontaneously emitted rays or subatomic particles from matter, a property which came to be known as radioactivity.

Front 2

Pierre and Marie Curie

Back 2

Building on the work of Becquerel, Pierre and Marie Curie discovered the radioactive elements polonium and radium.

Front 3

Credited with the first use for treatment of breast carcinoma

Back 3

E. H. Grubbe

Front 4

Treatment may be better tolerated and more effective if delivered more slowly with modest doses per day over several weeks.

Back 4

Claude Regaud

Front 5

Henri Coutard

Back 5

Pioneered the use of fractionated Radiotherapy in a wide variety of tumors

Front 6

Robert Jemison Van de Graaf

Back 6

built the first electrostatic generator

Front 7

a system of measuring radiation

Procedures for cleaning up accidental radioactive spills

Back 7

Edith Quimby

Front 8

built the betatron – 2MeV – 40MeV
Creating a radiation beam that produced electrons and photons for treatment

Back 8

Donald A Kerst

Front 9

Cobalt 60

Back 9

Faster at delivering the dose and more cost effective.
Provided a significant dose below the skin surface which enabled the skin sparing harsh effects.

Front 10

Linear Accelerators

Back 10

capable of producing high energy, deeply penetrating beams, allowing for the very first time treatment of tumors deep inside the body without excessive damage to the overlying skin and other normal tissues

Front 11

Deliver high doses to a small tumor
Uses extremely accurate image guided tumor targeting and patient positioning
Small tumors with well defined edges

Back 11

Stereotactic radiosurgery – SRS

Front 12

Treats tumors that lie outside the brain and spinal cord
Small isolated tumors
Lung, liver, prostate
Immobilization devices

Back 12

Stereotactic body radiation therapy – SBRT

Front 13

Proton therapy

Back 13

Protons deposit much of their energy at the end of their path
Reducing exposure of normal tissue

Front 14

Interstitial Brachytherapy

Back 14

Radiation source placed with the tumor tissues
Breast and prostate

Front 15

Radiation source placed within a surgical cavity or body cavity
Chest

Back 15

Intracavitary Brachytherapy

Front 16

Orthovoltage

Back 16

150 kv to 500 kv

Front 17

Van de Graff

Back 17

2 MeV

Front 18

Betatron

Back 18

2 MeV to 40 MeV

Front 19

Optimize both radiotherapy and radiosurgery
Seamlessly integrates respiratory gating, imaging and treatment techniques

Back 19
