Optimis – Precision Care

As a group of senior clinicians with a strong presence in the neurostimulation community, Optimis are very proud to provide world-class Repetitive Transcranial Magnetic Stimulation (rTMS). For optimal results in treating Depression, Pain, OCD, PTSD and other conditions, the accurate placement of the rTMS coil over the targeted brain area is critical. More conventional methods in rTMS are based merely on external landmarks of the head (5 cm rule, 10-20 EEG). This leads to inaccuracies in targeting of this brain area and henceforth suboptimal results in both rTMS research and therapies, with high variability in treatment outcome for different patients.

At Optimis – Precision Care we utilise MRI-guided neuro-navigation for precise and real-time delivery of rTMS pulses. Neuronavigation aligns the MRI scan acquired at an earlier point in time with the head of the patient, by measuring several fiducial points on the head with a tracker. The rTMS coil and the head of the patient are also tracked. This permits Neuronavigation software to accurately guide a rTMS pulse to the intended neuroanatomical structure with millimetre precision.

Several groups have now demonstrated clearly increased efficiency of MRI-guided neuro-navigation rTMS in treatment of e.g. depression (Fitzgerald, 2009). By using an individualized MRI scan of the subject, the rTMS coil can accurately be guided to the specific brain target and by doing so correct for differences in the shape and the size of that specific brain (Ruohonen, 2010) and the outer shape of the head.

Optimis is proud to offer the highest standard of rTMS, both for our expanding arenas of clinical treatment also for our developing professional affiliations within research.


Meet the team

Dr Davinder Hans


Davinder graduated in medicine from the University of Western Australia and completed his Postgraduate Training in Psychiatry in Western Australia. Davinder has done further Masters level training in Mood & Anxiety Disorders (University of Maastricht, The Netherlands) and Psychotherapy (RANZCP Cert Psychotherapy Psych). He has been credentialed for rTMS treatment by the Black Dog Institute, Sydney. Davinder has also done further training in Youth Mental Health and Autism Spectrum Disorder assessments.

He has a keen interest in teaching and research. Davinder has adjunct academic appointments at both University of Notre Dame Australia and University of Western Australia. Davinder has published research articles in psychiatry journals, and currently is the Principal Investigator at Hollywood Private Hospital for the Ramsay Health’s International Consortium for Health Outcome Measures (ICHOM) Depression and Anxiety Patient Reported Outcome Measures research study.

Davinder is the first author of the chapter on Anxiety Disorders (Chapter 8) in the Australian text, Foundations of Clinical Psychiatry 4th Edition 2017, and he has written academic material for undergraduate psychiatry teaching. Having a broad training in a range of disciplines including psychopharmacology and the psychotherapies, Davinder utilises these skills in assessment and treatment of his patients. In Hollywood Private Hospital, Davinder is the Clinical Lead of both the Trauma Recovery and Growth Program and the repetitive Transcranial Magnetic Stimulation (rTMS) Service. Outside Hollywood Private Hospital, Davinder is the Head of Clinical Services of Youth Mental Health in the Public Sector.

Dr Richard Magtengaard


Richard is a Consultant Psychiatrist with near 20 years of clinical and administrative experience, originating from working within the Public Mental Health arenas, later moving onto establish a broad set of interests within the Private Practice and Not for Profit setting.

Dr Magtengaard served for 10 years as a Commissioned Officer (Bridge/Harbour Watchkeeping and Navigation) within the Royal Australian Navy, before retiring to complete his Postgraduate Degree within Medicine (MBBS).

Richard is currently the Director of the Military Trauma Recovery Programme across 3 busy sites of care, namely Marian Centre Hospital - a 69 bed Tier 1 DVA Accredited private hospital in Wembley, Salvado - an interdisciplinary setting for specialist care within Subiaco and ANZAC House Veteran Central Perth. He remains dedicated to assisting Defence Personnel, our Veterans, First Responder Organisations and their families who have sustained physical and psychological traumas during the performance of their duties.

Richard values his role as the Operations Manager within Optimis, alongside being a senior member of the St John Ambulance Expert Advisory Group. He remains an active member of the Australasian Military Medical Association (AMMA) and has developed lasting affiliations with ADF Joint Health Command (JHC), Returned Services League WA (RSLWA), ANZAC House Veteran Central, St John Ambulance (SJA), West Australian Police (WAPOL), Department of Fire and Emergency Services (DFES) and numerous other Ex-Service Organisations (ESOs).

Richard is passionate about the future of evolving health technologies to improve outcomes in care, including neurostimulation with rTMS (repetitive transcranial magnetic stimulation).
