What is the difference between IMRT and VMAT?
- Highly conformal target volume dose with lower dose to critical structures than IMRT or 3DCRT, as dose is spread over more angles.
- Faster delivery times and lower MU's (especially single arc IMAT) when compared with IMRT.
- Non-co-planar arcs possible.
- Comparable plans to helical tomotherapy, but performed with a conventional linac.

Most side effects generally go away within a few weeks to 2 months of finishing treatment. But some side effects may continue after treatment is over because it takes time for healthy cells to recover from the effects of radiation therapy. Late side effects can happen months or years after treatment.

Missed Radiation Therapy Sessions Increase Risk of Cancer Recurrence. Patients who miss radiation therapy sessions during cancer treatment have an increased risk of their disease returning, even if they eventually complete their course of radiation treatment, according to a new study.
What is radiation simulation?
Before you begin radiation treatment, your radiation therapy team carefully plans your treatment in a process called radiation simulation . Treatment planning usually involves positioning your body, making marks on your skin and taking imaging scans.

How long does it take to relax after radiation?
After simulation, you’ll have a few days to a few weeks to relax while your radiation oncologist creates a unique plan of treatment taking into account your diagnosis, the type of radiation machine that will be used, the amount of radiation needed and the number of treatments to be given.
How long does it take for a doctor to review a cancer case?
It may take several minutes for the doctors to thoroughly review your case before they speak with you. After this visit you may be scheduled to start the radiation process, or you may be asked to return for a follow-up visit depending on the type of cancer and your individual treatment plans.
What is a sim appointment?
For most types of treatment, a simulation (SIM) appointment will be scheduled. The purpose of this visit is to outline or map the exact area to be treated.
What is informed consent for radiation?
Giving permission for radiation therapy. If you choose to receive radiation therapy, your health care team will ask you to sign an "informed consent" form. Signing the document means: Your team gave you information about your treatment options. You choose to have radiation therapy.
What is simulation in radiation therapy?

LCRP dosimetrist explains the process of how your radiation therapy starts before you even get there
There’s a team at the Nancy N. and J.C. Lewis Cancer & Research Pavilion that you may never meet. But if your cancer diagnosis requires radiation therapy, they are the ones planning your treatment. Their commitment is to ensure the highest quality of care.
The process
It starts with a CT scan called a simulation. Imagines will be taken in preparation for planning the treatment. Those images will help the dosimetry team tailor the treatment to each patient’s body and the specific machine that they will be treated on. At the LCRP, those machines include the TrueBeam and CyberKnife.
The patient experience
If radiation treatment is needed, each patient can expect to go through a thorough planning process, Wynn says. Even patients with benign conditions that need radiation therapy will start treatment with a plan.
Treatment Planning Process
- After simulation, details are reviewed by the medical dosimetrists and physicists. They calculate the exact dose and course of treatment with the goal of killing the cancer while limiting dose to healthy tissue. They use treatment planning software to help them design the best possible treat…
Quality Assurance
- After the radiation oncologist approves your treatment plan the physicists will check that your specific plan works on the treatment machine it was created for. Once this is done you can start your radiation treatments.
Set-Up
- You will be placed on the treatment table in the same position you were in for your simulation. The therapists will align your tattoos to the lasers in the treatment room and take a set of X-ray films. These films will be matched with the simulation films to make sure the treatment is given to the right area. You may be asked to move your body to align yourself for treatment. Your oncologist …
Daily Treatments
