What is KVCT imaging?

What is KVCT imaging?

™ ClearRT™* helical kVCT imaging provides clinicians with clear high-fidelity images for use in radiation therapy treatment delivery and planning. The enhanced image clarity provided by ClearRT, enables clinicians to efficiently see more, know more, and do more in comparison to conventional treatment systems.

What is step and shoot IMRT?

Present IMRT technology affords the ability to treat patients using several different modes. The static modes, step-and-shoot (SS) and sliding window (SW), deliver dose from a discrete number of beam angles.

What is KVCT in radiotherapy?

Generally, all contours for radiotherapy planning are delineated on kilovoltage computed tomography (KVCT) scans without contrast. Improvements in KVCT technology allow accurate contouring, planning of radiation therapy (RT) and individualization of therapy for each patient.

How is IMRT delivered?

Intensity-modulated radiotherapy (IMRT) uses linear accelerators to safely deliver precise radiation to a tumor while minimizing the dose to surrounding normal tissue. Your radiation oncologist will speak with you to determine whether IMRT is the most appropriate treatment for you.

What type of radiation is IMRT?

Intensity-modulated radiation therapy (IMRT) is an advanced type of radiation therapy used to treat cancer and noncancerous tumors. IMRT uses advanced technology to manipulate photon and proton beams of radiation to conform to the shape of a tumor.

How long does IMRT treatment take?

How Long Does IMRT Treatment Last? IMRT is usually given to you five days a week for four to eight weeks. The total dose of radiation and the number of treatments you need will depend on the size of your prostate cancer, your general health, and other medical treatments you may need.

Is IMRT therapy safe?

IMRT is a tremendous advance in the safe and effective delivery of radiation. However, it also requires much more time and resources from cancer clinics, radiation oncologists, physicists, radiation therapists, dosimetrists, nurses and their support staff to be done correctly.

What are the side effects of IMRT?

Depending on the treatment area, other early side effects of IMRT may include:

• Hair loss in the treatment area.
• Difficulty swallowing.
• Problems with eating and digestion.
• Diarrhea.
• Nausea and vomiting.
• Headaches.
• Soreness and swelling in the treatment area.
• Urinary and bladder changes.

How successful is IMRT?

The majority of patients who were treated with intensity-modulated radiation therapy (IMRT) remained alive with no evidence of disease after an average follow-up period of eight years. Researchers followed 561 men who were treated for prostate cancer with IMRT at Memorial Sloan-Kettering Cancer Center.
