What is conventional simulator?
Conventional simulation implies the use of a machine capable of the same mechanical movements as treatment units. Images obtained from these machines are essentially two dimensional with the facility to acquire a limited number of axial slices to provide patient contours and tissue density information.
Which of the following are benefits of CT simulation?
Terms in this set (42)
- The benefits of CT simulation include the ability to view all critical structures, which allows for more accurate treatment planning.
- Common artifacts in CT scanning are:
- What does spatial resolution measure?
What is a radiotherapy simulator?
A simulator is a diagnostic x-ray source configured to mimic the geometric beam delivery configuration of a radiotherapy linac. The x-ray source is mounted on a rotating gantry, similar to a linac, with a detector rotating in the opposite position on the far side of the patient.
What is CT simulation for radiation therapy planning?
CT simulation includes a CT scan of the area of your body to be treated with radiation. The CT images acquired during your scan will be reconstructed and used to design the best and most precise treatment plan for you.
What is a CT simulator?
A CT simulator ( CT -S) is a real-time, CT -linked, 3-D treatment planning system, which consists of a CT scanner, a multi-image display, a treatment planning device with real-time visual optimization, and a laser beam projector.
How long does a CT simulation take?
A CT scan will be taken to verify the anatomy and assure accuracy. If needed, immobilization devices such as a face mask or a leg mold will be made at this time. Your skin will be marked with small dots of permanent ink (tattoos) to ensure that the precise area is treated each time. The SIM visit takes about one hour.
What is CT best for?
CT scans are better for seeing complex fractures, spinal cord injuries, osteoporosis damage and bone tumors. Head conditions: Hemorrhaging, brain calcification, tumors and blood flow problems to the brain can be seen on a CT scan.
What is the purpose of a CT scan?
A CT scan can be used to visualize nearly all parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment.
What are the advantages of a CT scan?
Benefits of CT include more effective medical management by:
- determining when surgeries are necessary.
- reducing the need for exploratory surgeries.
- improving cancer diagnosis and treatment.
- reducing the length of hospitalizations.
- guiding treatment of common conditions such as injury, cardiac disease and stroke.
Why do a CT scan before radiation?
Most patients have a CT before starting radiation treatments as part of the simulation procedure. The scan utilizes a low radiation dose protocol and often does not involve contrast in the bloodstream.
What can I expect from a radiation simulator?
During your simulation, you will have x-rays and your skin will be marked with little tattoo dots. These marks identify the area that will be treated. Your simulation will take at least an hour, but can be longer depending on the treatment your doctor has planned for you.
What can I expect from CT simulation?
The purpose of the CT simulation is to determine the exact location, shape and size of the tumor to be treated. This appointment will take approximately one hour. The CT technician will come and get you from the waiting room and take you to the CT room. A signed consent will be obtained before you start the scan.
How does radiation therapy feel?
Most people feel little to no discomfort during this treatment. But some may experience weakness or nausea from the anesthesia. You will need to take precautions to protect others from radiation exposure.
What are the side effects of radiotherapy?
Ask your care team about the side effects you might get.
- Sore skin. In some people, radiotherapy can make the skin sore and red (similar to sunburn), darker than normal or dry and itchy.
- Hair loss.
- Feeling sick.
- Problems eating and drinking.
- Stiff joints and muscles.
- Sex and fertility issues.
What are the steps of radiation therapy?
Overall, there are five basic steps of radiation therapy that we can share to give patients an idea of what to expect. These steps include initial consultation, simulation, treatment planning, treatment delivery and post treatment follow-up.
