Radiotherapy

What is Radiotherapy

Radiation therapy is the use of radiation to treat diseases. It is typically used to treat of cancer. It may use a radioactive material or particle accelerator or other source of ionizing radiation that can kill or damage cancerous cells.

Benefits of Radiotherapy

The advantages of radiation therapy include: death of a large proportion of cancer cells within the entire tumor (there are minimal, if any, cancer cells are left behind in small tumors; thus, radiation alone may be used to cure certain small tumors).

RADIOTHERAPY DEPARTMENT OF THE HOSPITAL

The objective of Radiotherapy, since it was recognized for cancer treatment has been maximum delivery of dose to the tumor without excessive side effects resulting in improved local control. The only way of delivering higher doses to the tumor are brachytherapy, stereotactic radiotherapy, radiosurgery, intensity modulated radiotherapy and Intraoperative radiotherapy out of this external radiotherapy is still the main modality used by the radio-oncologists world over.

When the Lucknow Cancer Institute became operational in the year 2001, Radiotherapy was provided by the Cobalt 60 Unit Elite-80 model, which was the latest in the market and first in the Private Sector in the country. The model could take up a very high source of virtual stimulated in the treatment was started by Lucknow Cancer Institute only. For this ORFIT immobilizing device was used for all the patients as a routine at Lucknow Cancer Institute, a pioneering effort in the treatment of cancer cases.

The cancer care facility at the Lucknow Cancer Institute was further upgraded in February 2019 and HalyonTM, introduced by Varian, an entirely new device for cancer treatment was installed.

High Quality of care: Halcyon is an advanced treatment system re-envisioned for the future of radiotherapy. It is designed with a 6-point system for patient safety. This contributes to a faster, simpler, more convenient, more efficient and more accessible experience for the people who are working together to achieve victories over cancer.

Simple, efficient, and purposeful, Halcyon offers the potential to replicate the treatment from machine to machine, practice to practice—putting patients and staff more at ease and delivering a high standard of care. Its advanced design is optimized to deliver quality cancer therapies for every appropriate patient and every care center around the world.

POTENTIAL BENEFITS:

CORE TECHNOLOGIES ENABLE
EXCELLENT QUALITY TREATMENTS

 

  • -System capabilities allow for advanced techniques such as Multi-arc VMAT, Many-field IMRT.
  • -Powerful 800 MU/min dose rate, 6MV, Flattening Filter Free (FFF) beams.
  • -A gantry that rotates up to four times faster Collimator rotation between fields enhances treatment conformity.
  • -New linear motor design for shifting patients smoothly and quietly.

 

NEW GENERATION MLC

 

  • -Fast leaf speed of up to 5cm/sec that’s specifically engineered to support the faster gantry rotation.
  • -Dual-layer offset leaf technology with 100% overtravel capability enables more efficient treatments.
  • -Stacked and staggered” approach provides optimized modulation and reduced interleaf leakage.

 

100% IMAGE GUIDANCE (IGRT), IMRT, VMAT(Rapid ARC)

-Fast, sharp, ~15-second CBCT image capture; 7 seconds for a 2-D image.
-100% image guidance enables consistent & confident workflow.
-Imaging dose is included in the treatment plan.
-Beam-on time typically about *2 minutes whether RapidArcTM or IMRT( *may differ from plan to plan).
-Rapid imaging and treatment duration to limit time on couch for patient.

HDR BRACHYTHERAPY

Brachytherapy is a procedure that involves placing radioactive material inside the body of the patient. It is also known as internal radiation. This facility is available in the Hospital and is most commonly used in vaginal, cervical/uterine cancers.
