What is heavy ion radiation?
Radiation releases energy while traveling through space or matters in the form of waves or particles. Radiation composed of particles heavier than electrons is called a particle beam, and radiation composed of particles heavier than helium is specifically called a “heavy-ion” beam.
What is ion beam therapy?
For certain kinds of cancer, the most effective therapy does not use x-rays or gamma rays but beams of ions, the electrically charged cores of atoms, including hydrogen ions (protons) and heavier ions such as carbon and neon.
How much does carbon ion therapy cost?
Proton therapy centers cost about $200 million; the more massive carbon ion centers run about $300 million. Carbon requires a longer pathway to reach its optimal speed in a particle accelerator and thicker shielding to prevent leakage of radiation.
Which ion is used in cancer treatment?
The power of carbon-ion radiotherapy to kill cancer cells is much stronger than photon and proton beams. Compared to photon beams and proton beams, carbon-ion radiotherapy is highly capable of killing cancer cells. It is therefore more effective on tumors which is resistant to conventional photon/proton radiotherapy.
What particles are used in radiotherapy?
Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells.
How does carbon ion therapy work?
What is carbon ion therapy / heavy ion therapy? With carbon ion irradiation, charged carbon nuclei are directed at the tumor. These are particularly heavy and loaded with energy; thus, this radiation is also called heavy ion therapy. HIT is one of a few centers worldwide offering heavy ion therapy.
How does heavy ion therapy work?
Heavy ions were initially proposed for clinical radiotherapy based on two key requirements for effective treatment: (1) to deliver a high killing dose to a localized tumor target while sparing normal tissue lying in the treatment volume, and (2) to reduce the radioresistance of hypoxic cells (i.e., to obtain an …
What are the advantages of ion therapy?
Heavy ion therapy can severely damage the tumor while minimizing damage to surrounding tissues. Heavy ion therapy has less toxicity (adverse effects) than conventional radiotherapy. Heavy ion beams have stronger biological effects than X-ray….Advantages of Heavy Ion Therapy.

Where is carbon ion therapy available?
While carbon ion therapy was discovered in the United States in the 1970s, there currently are no carbon ion therapy treatment centers in North America. The technology is available only at a handful of centers in Asia and Europe.
How does ion therapy work?
Once they reach our bloodstream, negative ions are believed to produce biochemical reactions that increase levels of the mood chemical serotonin, helping to alleviate depression, relieve stress, and boost our daytime energy.
What is beam radiation?
Beam radiation is the solar radiation received from the Sun without having been scattered by the atmosphere. Diffuse radiation is that received from the Sun after its direction has been changed by scattering by the atmosphere. Fig. 5.5. Solar energy components.
Does heavy ion therapy work through the immune system?
Heavy ions can effectively kill tumor cells independently of TP53 or Bcl2 status (7), a promising clue for enhanced cell death and potential enhancement of release of neoantigens or overexpression of immunogenic epitopes.
