2 Dimensional Conventional Radiotherapy
Long established technique of radiotherapy. This type of radiotherapycanbe delivered with Cobalt machineorLinear Accelerator (LA). At our centre we have additional facility for CT scan based planning and verification with portal imaging
3 Dimensional Conformal Radio Therapy (3D-CRT)
Tumors are not regular, they come in different shapes and sizes. 3D-CRT, uses computers and high definition software with special imaging techniques to simulate the size, shape and location of the tumor.Computer Assisted Tomography (CT Scan), Magnetic Resonance Imaging(MRI Scan) and/or Positron Emission Tomography ( PET Scan) are used, individually or by fusion, to create detailed, three dimensional representations of the tumor and the surrounding organs. This therapy, uses a multileaf collimator (MLC) to frame precise radiation beam to atargeted area. The MLC is a device with a series of computer-controlled leaf-like plates. As the radiation beams are very precisely directed, adjacent normal tissues receives less radiation and are able to heal quickly. Hence, this treatment is superior to the conventional 2D treatment.
Intensity Modulated Radiation Therapy (IMRT)
IMRT is an advanced mode of high precision radiation. In IMRT, MLCs are used to subdivide (modulated) radiation beams into many beamlets aimed at the tumor, from various directions. Also, intensity of each of these beamlets can be adjusted individually. Thus, it is a specialized form of 3D-CRT that allows radiation to be shaped exactly to fit the tumor. Using IMRT, it is possible to further limit the amount of radiation that is received by healthy tissues near the tumor as compared to 3D-CRT. In many situations, this may also allow a relatively higher dose of radiation to be delivered to the tumor, increasing the chance of cure. As this method of treatment delivery is very accurate, proper positioning of the patient becomes crucial.

Image Guided Radiation Therapy (IGRT) helps to improve the delivery of radiation. It is a advanced type of IMRT which involves conformal radiation treatment guided by a CT scan (called Cone Beam CT), taken in the treatment room just before the patient is given the radiation treatment. The imaging information from the planning CT scan done earlier is overlapped on this Cone Beam CT. With this technique, movement of the tumor due to differences in organ filling or breathing or reduction in size can be tracked. Variations as small as one mm in daily positioning of the patient is detected and corrected instantly. IMRT improves the precision of radiation delivery while IGRT improves the accuracy of radiation delivery by incorporating temporal changes. Hence,

IGRT is by far the most advanced form of radiotherapy today and Nirali Memorial Radiation Centre is the first to install and use it in Southern Gujarat.

Somatom Emotion 6 CT Simulator for EBRT planning and Virtual Simulation
CT Simulator and radiotherapy softwares are used for computerised planning of high precision External Beam Radiotherapy

For virtual simulation patient images are acquired with patient on couch and image reconstructions are done by software. Based on these images radiotherapy can be planned in the absence of patient

Three orthogonal moving lasers are used to extrapolate point of reference for plan execution and radiotherapy delivery

Precise delivery of radiation to target organs and maximum sparing of adjacent critical structures thus maximises therapeutic gain

Brachytherapy is also known as internal radiation. It involves placing radioactive material inside applicators which are inserted into a tumor itself or into it’s surrounding tissue. As the radiation sources are placed closed to the tumor cells, a large dose of radiation can be delivered. At NMRC, high-dose-rate remote after loading machine (Nucletron) is used for this purpose. Following this imaging CT scan is done and the scan is transferred to the Radiotherapy planning system . A specific plan is selected and transferred to HDR machine after the detailed study. Empty applicators are then connected to the radiotherapy source machine, which automatically moves the Ir-192 radioactive source inside and outside the applicator at predetermined intervals and dwell position. During the entire treatment, the radioactive source does not come in direct contact with the patient’s body or the organs. Subsequently, the applicators areremoved and the patient is discharged. NMRC is one of the few hospitals using CT Scan based planning (3D planning brachytherapy).

Brachytherapy is useful mainly for treatment of cancers of Breast, Gynaecological sites, Head & Neck region, GI region. Fully equipped dedicated operation theatre has been constructed for brachytherapy procedures.

Atomic Energy Regulatory Board has recognized One Year Internship /Medical Physics Residency Programme.
