Biography
Mohib created Radulator to make commonly used radiology and clinical calculators faster,
clearer, and easier to verify at the point of learning or care. His work spans interventional
radiology, medical device design, AI-assisted clinical tools, and browser-based software for
medical education.

What is Radulator?
Radulator is a collection of medical calculators focused on radiology, neuroradiology, trauma, cardiac imaging, breast imaging, women's imaging, clinical decision, hepatology/liver, urology, interventional, and nephrology. Each calculator is built using formulas from
peer-reviewed literature, with references to the original studies.
All calculations are performed locally in your browser. We never collect, store,
or transmit any patient data or clinical information you enter.
