- Introduction: The Evolution of Hybrid Medical Imaging
Medical imaging has undergone major leaps over the past few decades—from CT scans to MRI, PET, and molecular imaging. Yet, each modality has certain limitations. Optical imaging provides high contrast but poor depth; ultrasound offers good depth but low molecular specificity.
Photoacoustic imaging bridges this gap by using pulsed laser light to generate ultrasound waves through thermoelastic expansion inside tissues. These signals are captured by ultrasound transducers, forming high-resolution images that display structural, functional, and molecular information simultaneously.
As the healthcare ecosystem shifts toward personalized medicine, minimally invasive diagnosis, and cost-effective imaging workflows, PAI is increasingly recognized as a technology with transformative potential.
