About Advanced Centre for Radiation Oncology (ACRO)
Advanced Centre for Radiation Oncology (ACRO) is the new wing of the Division of Radiation Oncology at Nanavati Hospital. The new wing situated at third level basement boasts of dual energy photon linear accelerator from Elekta, a Swedish company. Precise Digital Linear Accelerator not only has 6 & 15 MV photons but six levels of electrons as well. LA is also equipped with MLC for intensity modulated radiation with online imaging. Virtual wedge is a unique feature of this machine. In vivo digital dosimeter monitors actual delivery of planned radiation. Precise plan is a high end computerized planning system connected to CT & MRI scans to facilitate virtual simulation and IMRT planning is done on this machine with a special algorithm using inverse planning.
What does it all mean to the patient? This is about high precision delivery of high energy radiation to cancer embedded deep in the entrails of the body, but at the same time sparing radiation injury to normal tissues. It is much like snugly fitting stocking on a delicate leg, high dose of radiation enveloping tumour. The advantage for the patients would be to reduce acute and late toxicities while enhancing chances of cure.
Prostate cancer, Head and neck cancers and cervical cancer are eminently suitable for IMRT.
