About Sonosis

Sonosis is a specialised ultrasound practice focused on delivering high-quality, patient-centred diagnostic imaging in a more personal and efficient setting.

Founded by Caroline van Graan, Sonosis was built with the vision of creating an alternative to traditional radiology — one that prioritises accuracy, accessibility, and meaningful clinical collaboration.

We provide a wide range of ultrasound (sonar) services, including pregnancy scans, musculoskeletal imaging, abdominal and pelvic studies, Doppler examinations, and ultrasound-guided procedures.

A More Personal Approach to Ultrasound

At Sonosis, every scan is performed with attention to detail and clinical context. We take the time to understand each patient’s symptoms and concerns, ensuring that imaging is not just performed, but interpreted meaningfully.

Our reports are delivered on the same day, allowing referring doctors and patients to make informed decisions without unnecessary delays.

Working Closely With Your Healthcare Team

We work in close collaboration with general practitioners, physiotherapists, specialists, and other healthcare providers to answer specific clinical questions and guide patient management.

This approach allows us to go beyond routine imaging and provide targeted, relevant insights that support better outcomes.

Accessible, High-Quality Care

Sonosis is built on the principle that patients deserve both high-quality imaging and a personalised healthcare experience.
