Hey guys, welcome back to my channel. So today we're going to be talking about how to use Gemini Flash.

/X-ray human bodynX-ray radiography (projectional radiography) produces images by passing high-energy electromagnetic radiation through the body onto a detector. The resulting image displays structural densities based on how strongly different tissues attenuate (absorb) the X-ray beam:nn• Bone & Calcified Tissue (White/Radiopaque): High physical density and atomic number (calcium) absorb the most X-ray photons.nn• Soft Tissue & Muscles (Grayscale): Intermediate absorption creates varying shades of gray across organs, muscle groups, and fat layers.nn• Air & Gas (Black/Radiolucent): Low density allows X-ray photons to pass through unhindered (e.g., lungs, digestive tract).nnChest X-ray detailing key thoracic anatomical structures.
