What Combines Optical Imaging with MRI?
Optical imaging and MRI reveal tissue through different physical signals. Combining them can add complementary detail, though the methods have different strengths, scales, and practical limits.
Light & Lasers
The ways light reveals tissue, carries signals, and delivers precisely controlled energy.

Photodynamic Therapy Is More Than Shining a Lamp
Photodynamic therapy depends on a photosensitizing drug, a carefully chosen light exposure, and oxygen-driven chemistry. Its local action can spare surrounding tissue in some settings, while limited light penetration constrains which tumors it can reach.
Fiber Optics as a Route for Medical Light
A hair-thin glass fiber can carry light around bends and into places a straight beam cannot reach. In medicine, that route enables both internal viewing and carefully aimed local treatment, with distinct limits and purposes.
What Makes Laser Light Useful in Surgery?
A laser concentrates light into a narrow, controlled beam that can transfer energy to selected tissue. Wavelength, delivery path, and tissue response shape its surgical uses and its limits.
