Icon clinicians recognised among world’s top experts in stereotactic treatment

Icon Writers / 28 Jan, 2026

Icon Group clinician Professor Shankar Siva and Icon Group Deputy Chief Medical Officer Associate Professor Matthew Foote have been named among the Top Scholars global list of 100 of leading experts in stereotactic (precision) brain and body radiotherapy. 

They are the only Australian clinicians to be included on the list, with Prof Siva ranked third in the world and A/Prof Foote making his debut at number 95.

The prestigious list highlights the significant contribution of clinicians to the international academic field of stereotactic radiotherapy over the past five years.  Icon Group CEO Mark Middleton said the recognition reflects the exceptional standard of expertise shared across Icon’s 350+ specialist network. 

World leading care 

“It’s an important endorsement of the quality of expertise and care we bring to our patients,” said Mark. 

“Shankar and Matthew are both driving the next generation of precision cancer treatment. Shankar is a world leader in stereotactic body radiotherapy and is considered an international thought leader in stereotactic body treatment in a range of primary tumours as well as the metastatic setting.  

“Matthew is internationally recognised in the management of a benign, malignant and vascular brain and base of skull conditions, and has been instrumental in the establishment of Gamma Knife programs here in Queensland, Australia.  

“This recognition simply reinforces the clinical strength we have across our Icon network and the reason patients trust us foremost with their care.” 

Together, Prof Siva and A/Prof Foote lead two of Icon’s flagship stereotactic programs, bringing worldclass capability to patients through CyberKnife and Gamma Knife technology respectively.

Recognising next generation leadership – Dr Mihir Shanker 

The announcement coincides with the appointment of Dr Mihir Shanker as the Australian Ambassador for the International Stereotactic Radiosurgery Society (ISRS). 

This prestigious role reflects Dr Shanker’s growing influence in the stereotactic community and underscores Icon’s commitment to developing the next generation of global clinical leaders. 

“The fact that Mihir has been asked to take on that role shows that not only do we have world leaders in the stereotactic space, but we also have the next generation of talent coming through,” Mark said.  

Our clinicians are taking an active role internationally, and that positions Icon not just locally but as a global leader in stereotactic treatment. 

Best care possible 

Mark added that these combined achievements should give patients additional confidence in the expertise behind their care. 

“Our patients can be confident they truly are receiving the best care possible across our global network.”
