Cold Plasma: Chemistry, Dose, and Wound Healing
A close examination of how a cool electrical discharge could influence wound repair, what randomized trials actually measured, and why seconds of exposure do not define a transferable biological dose.

MRI: From Spin Resonance to K-Space
Follow the signal from a small imbalance in nuclear spins to spatial encoding and reconstruction, with worked examples showing why frequency, resolution, field of view, noise, and scan time are different quantities.
Proton Therapy Beyond the Bragg Peak
A better dose distribution is a powerful starting point. Range uncertainty, tissue biology, and contrasting randomized trials explain why it is only the beginning of the clinical argument.
Focused Ultrasound: Heat, Bubbles, and Evidence
How focused sound deposits heat or drives mechanical bubble activity, why imaging and motion control matter, and how indication-specific FDA authorizations differ from evidence of clinical benefit.
