Smart arc and dynamic treatment planning

Smart Arc Therapy in Rangapani, Siliguri for Advanced Cancer Care

Smart Arc Therapy is an advanced form of rotational Intensity-Modulated Radiation Therapy (IMRT). In this technique, radiation is delivered continuously as the linear accelerator’s gantry rotates around the patient. The intensity and shape of the beam are dynamically modulated by using multileaf collimators, allowing for very conformal dose delivery to the tumour while sparing as much healthy tissue as possible.

At Manipal Hospital, Smart Arc Therapy in Rangapani, Siliguri is delivered through the latest linear accelerators and treatment planning systems. The oncology team combines deep clinical expertise with cutting-edge technology to ensure patients receive accurate, safe, and comfortable treatment with minimal side effects.

Why Is Smart Arc Therapy Performed?

Smart Arc Therapy in Rangapani, Siliguri, is used for patients with tumours located near critical organs. This is particularly beneficial for patients who cannot tolerate an extended treatment session.

It is used to:

• Deliver Radiation from multiple angles using a single arc

• Dynamically shape and adjust the beam intensity in real time

• Increase the precision of Radiation dose delivery

• Reduce overall treatment time without compromising outcomes

• Effectively treat tumours in complex or sensitive locations

What Is Dynamic Radiation Planning?

Dynamic Radiation planning in Rangapani, Siliguri is a sophisticated method of tailoring Radiation treatment by continuously modulating beam parameters based on the tumour’s shape and surrounding anatomy. This technique involves real-time adjustment of:

• Dose rate

• Beam angle

• Multileaf collimator (MLC) positions

It is to deliver radiation that precisely conforms to the tumour while reducing exposure to healthy tissues. It forms the planning foundation for advanced rotational IMRT techniques such as Smart Arc Therapy, ensuring enhanced tumour targeting, better dose conformity, and reduced toxicity.

What Happens Before the Therapy?

Before the therapy, a personalised treatment plan is developed by the Radiation oncologists and medical physicists.

This process includes:

• Detailed imaging (CT or MRI) to map the tumour and nearby anatomy

• Advanced software that calculates the optimal beam angles, arc paths, dose rate, and MLC movements

• Quality assurance checks to ensure the treatment plan is safe and accurate before the first session

What to Expect During the Smart Arc Therapy

Smart Arc Therapy in Rangapani, Siliguri,  is delivered in a modern Radiation suite using linear accelerators equipped with dynamic MLCs and real-time image guidance. During each session:

• Patients are positioned comfortably using custom-made devices that help them stay still during the session

• The gantry rotates around the patient, delivering modulated Radiation from multiple angles

• Beam shape and intensity are adjusted in real time based on the treatment plan

• Each session typically lasts only a few minutes

• This streamlined approach offers both efficiency and precision.

What Happens After the Treatment?

Post-treatment, patients are placed on a structured follow-up plan managed by a multidisciplinary oncology team.  

Post-treatment care includes:

• Periodic imaging to assess the tumour response

• Monitoring for and managing any treatment-related side effects

• Regular consultations to evaluate long-term outcomes and ensure recovery

• Rehabilitation support to encourage optimal recovery after treatment 

What are the Pros and Cons of Smart Arc therapy? 

Benefits of Smart Arc Therapy in Rangapani, Siliguri, include:

• High-precision targeting of the tumour

• Shorter and more comfortable treatment sessions

• Reduced toxicity to nearby healthy tissues

• Applicable for tumours in anatomically challenging locations

• Treatment is provided through careful planning and proper monitoring.

Potential Risks include:

• Mild fatigue or skin irritation

• Organ-specific side effects depending on the treatment area

• Rare long-term effects, particularly in sensitive tissues

At Manipal Hospitals, with dynamic Radiation planning in Rangapani, Siliguri, these risks are minimised through accurate treatment design and continuous monitoring.
