You may click on any of the following images for a larger version.
Biomedical Imaging
Explores the biomedical imaging technologies of X-ray radiography, X-ray CT, magnetic resonance imaging (MRI), positron emission tomography (PET), bone scanning, and sonography. Learn basic image processing techniques such as false colorization, brightness and contract enhancement and animation to evaluate medical images for their diagnostic value.
The Cell Factory
View cells and organelles at up to 100,000 times magnification with transmission electron micrographs. Set scales for these images and accurately measure the size of cellular structures. Use the cutting and pasting capabilities of NIH Image to copy, scale and paste images of organelles into your own model cell.
Tissue Study
Examine color light micrograph images of epithelial, connective, muscular and nervous tissue to learn important features. Use the measuring and profile plotting tools to quantify and visualize differences in tissue types. Test your ability to identify the tissue types with a Tissue Quiz at the end.
Thick and Thin
Observe and measure the layers of the skin to discover the structure and function of each layer in maintaining homeostasis. Measure the amount of melanin present in pigmented and nonpigmented skin to explore its protective effects.
All Stressed Out
Compare digital cross-sections of two femurs to explore factors related to bone structure and strength. Enhance the images to reveal stress lines in the trabeculae and measure the amount of bone in the necks of the femurs to determine which femur is stronger.
Articulations
Analyze joint motions using animated ³movies² and examine and measure joint structures in digital photographs from the National Library of Medicine¹s Visible Human Project.
Digital Brain Atlas
Use high quality digital photographs from the National Library of Medicine's Visible Human Project to learn cross-sectional brain anatomy. Use diagramming and color-tinting techniques to design and create your own digital brain atlases.
Brain's Blood Supply
Process a head and chest arteriogram to reveal details of the blood supply to the brain. Measure vessels to determine cross-sectional area and resistance to blood flow from the aorta to a capillary in the brain.
Blood Cells
Copy and past different blood cell types to a new image window to discover and compare the diagnostic features of each. Correlate size, shape, granularity and presence or absence of a nucleus with each formed element of blood.
Cardiac Dynamics
Use the copy and paste capabilities of NIH Image to overlay cardiac function graphs on top of one another to evaluate relationships between blood volume, blood pressure and electrical activity. Measure specific points along the curves of each graph to calculate important measures of cardiac function.
Up in Smoke
Measure the differences in proportion of alveolar air space to lung tissue present in normal and emphysematous lung tissue. Make hypotheses about the probable effects of emphysema based on your observations and measurements.
Digestive Landscapes
Investigate the tremendous increase in surface area due to the presence of plicae circulares, villi and microvilli. Use a geometric model of a cylinder to measure and calculate an estimate of the increase in surface area using light and transmission electron micrographs of these structures.
