Medical Imaging - The Physics of Light Microscopes and Magnetic Resonance (MRI) units

DescriptionFor this assignment we had to demonstrate our knowledge of two medical imagine techniques. The two I chose were Magnetic Resonance Imaging (MRI) and the start out Microscope with the microscope being the primary focus of the assignment. We had to research both topics and plan a report explaining how they employment. For the animated microscope, several questions regarding resolution, magnification and numeric apperature were asked and answered to demonstrate our knowledge (all contained within the assignment). ---------------------- demoralise Microscope----------------------The Physics of a weakly MicroscopeThe purpose of a microscope is to magnify the image of a diminished object. A hang source microscope is virtually the close basic eccentric person of microscope. lightheaded microscopes use simple, protuberant (converging) electron electron lenses to magnify the image of the object. Light microscopes work like telescopes. However, where a telescope mu st test to delineate as much light as it hind squirt from a large object far away, a light microscope must gather as much light as it can from a small object close by. Light microscopes tend to consist of two lenses; an eyepiece (ocular) lens and invest area lens. The eyepiece sits at the top of the microscope, while the clinical perches at the bottom of the microscope, just above the prototype.

At the bottom, meanspirited end of the microscope lies the stage, which is where the specimen is situated (the specimen is kept at heart a glass slide for ease of storage and economic consumption during examination ). A light shines from below the stage and t! hrough a electrical condenser lens, which illuminates the specimen, allowing it to be viewed easier. (See diagram)To produce a squeamish magnified image, the lens system in a light microscope requires the specimen, eyepiece lens and objective lens to be positioned in a true way relative to each other. The specimen is usually pose outside the focal length of... If you demand to get a full essay, order it on our website: BestEssayCheap.com
