How do proton beams work?
How does proton therapy work? 1 The proton begins its journey at the ion source. Within fractions of a second, hydrogen atoms are separated into negatively charged electrons and positively charged protons. 2 The protons are injected via a vacuum tube into a linear accelerator and in only a few microseconds, the protons’ energy reaches 7 million electron volts. 3 Proton beams stay in the vacuum tube as they enter the synchrotron, where acceleration increases their energy to a total of 70 million to 250 million electron volts, enough to place them at any depth within the patient’s body. 4 After leaving the synchrotron, the protons move through a beam-transport system comprised of a series of magnets that shape, focus and direct the proton beam to the appropriate treatment room. 5 To ensure that each patient receives the prescribed treatment safely and efficiently, the facility is controlled by a network of computers and safety systems. The gantry can revolve 360 degrees, allowing the beam to be delivered at any angle. 6 As protons come through the nozzle, a custom-made device (the aperture) shapes the beam of protons, and another custom-made device (the compensator) shapes the protons into three dimensions, delivering them to the depth of the tumor. 7 At maximum energy, a proton beam travels 125,000 miles per second, which is equivalent to the two-thirds the speed of light. 8 From the hydrogen canister to the patient, a proton typically travels 313,000 miles.
What is the advantage of proton beam therapy?
The advantage of proton therapy (also called proton beam therapy) is that the physician can control where the proton releases the bulk of its cancer-fighting energy. As the protons move through the body, they slow down and interact with electrons, and release energy. The point where the highest energy release occurs is the “Bragg peak.”.

What is the best radiation therapy for cancer?
Stereotactic radiation therapy delivers a high dose of radiation very precisely to a tumor. Stereotactic radiation therapy uses many different angles to focus the radiation at one small point, like a magnifying glass. There are two types of stereotactic radiation therapy: 1 Stereotactic radiosurgery (SRS). 2 Stereotactic body radiation therapy (SBRT).
What is IMRT in cancer?
IMRT is another way to deliver photons to treat a tumor, but with the benefit of sparing more healthy tissue. Planning IMRT also begins with a simulation. Similar to 3D conformal therapy, the tumor and normal organs are outlined on the CT in 3D (figure III, below). Multiple beams are positioned around the person to deliver the radiation. However, in IMRT, these beams are divided into a grid-like pattern, separating the one big beam into many smaller "beamlets."
What is external radiation therapy?
External radiation therapy: a beam of radiation is directed into the body. This may also be called x-ray therapy, 3D conformal radiation, intensity modulated radiation therapy (IMRT), cobalt, photon, or proton therapy.
How are X-rays used in radiation therapy?
When 2D, or conventional radiation therapy is used, X-ray films are used to guide and position the radiation beams. A machine called a “fluoroscopic simulator” is often used to plan the radiation treatments. The bones seen on the X-ray are used as landmarks to find where the tumor is and where to position the radiation beams in order to treat the tumor, while avoiding areas where there is no cancer. Planning does not take a long time and patients can usually start treatment quickly, compared to other kinds of radiation therapy that need more in-depth (and time consuming) planning. This type of treatment is often used for urgent treatments.
What is volumetric modulated arc therapy?
Volumetric modulated arc therapy (also known as RapidArc). Photon beams are the same type of beam used in X-ray machines, like those used to take chest X-rays. However, in radiation therapy, much higher energy photon beams are used.
How does IGRT work?
During treatment with IGRT, imaging scans are done over and over to guide treatment. The scans are read by computer software to find changes in a tumor’s size and location. This allows for changes in position of the patient and/or the planned radiation dose. The many images can increase the accuracy of the radiation treatment and decrease the amount of radiation to the nearby normal tissue.
What is a CT scan for tumors?
Many hospitals now have the ability to use a CT scan (Cat Scan) to plan radiation treatments for tumors. This process is called 3D conformal radiotherapy. CT-guided therapy allows the tumor and normal organs to be defined in three dimensions, as opposed to using the "flat" image of an x-ray (in “conventional” radiation therapy).
