Multispectral Method for Apple Defect Detection using Hyperspectral Imaging System Tao Tao‚ Master of Science‚ 2011 Directed By: Dr. Gang Qu‚ Associate Professor Hyperspectral imaging is a non-destructive detection technology and a powerful analytical tool that integrates conventional imaging and spectroscopy to get both spatial and spectral information from the objects for food safety and quality analysis. A recently developed hyperspectral imaging system was used to investigate the wavelength

Fusion Techniques for Multispectral and Panchromatic Images Abstract: Image fusion is the process of merging two or more images obtained from the same sensor at different times or from two or more sensors at the same instant. The objective is to obtain more information from the fused image than from the individual images. In satellite images‚ the lower spatial resolution multispectral images are fused with higher spatial resolution panchromatic images. The fusion should result in the transfer of

Diagnostic Imaging: X-Ray Diagnostic Imaging is medical tools used by doctors to see inside our bodies without actually opening the body. Diagnostic imaging can involve the use of radiation which could be dangerous if exposed to large amounts of. Diagnostic imaging allows doctors to find tumors‚ broken bones‚ pneumonia‚ etc. In general‚ diagnostic imaging is very helpful. X-Rays: This was one of the first types of diagnostic imaging. It uses radiation called Electromagnetic Waves. These

Magnetic resonance imaging (MRI) is a type of scanner that uses strong magnetic field and radio waves to produce complete images inside the body. An MRI scanner is a large tube that contains strong magnets. The patient lie inside the tube during the scan. The MRI scanner is used to observe almost any part of the body including the brain and spinal cord‚ bones and joints‚ breasts‚ heart and blood vessels and internal organs such as the liver‚ womb or prostate gland. The results of an MRI scan can

provide recommendations for turning around Kodak’s digital imaging business. Corporation Strategy Diversification in Medical and Commercial sector Between 1983 and 1993‚ Kodak adopted unrelated diversification strategy by expanding its business in health care and chemical industry with high profit potential. During that decade‚ Kodak acquired several pharmaceutical and bioscience companies‚ it also expanded its range of medical imaging products. This strategy could bring Kodak extra market share

The decision to perform CT/CBCT imaging depends on both the initial radiographic valuation and the clinical findings. If the plain radiographs are negative‚ with no signs of fracture‚ no fluid levels‚ no mucosal thickening of the sinuses‚ and no orbital or soft tissue emphysema and there is no indication of penetrating injury‚ then the chance of finding a significant midface fracture on CT/CBCT evaluation. There are very high incidence of intracranial damage in such patients‚ and there are important

Current Issues in Brain Imaging Technology Brain imaging technology has revolutionized the way doctors‚ scientists‚ and researchers are able to see the workings of this highly complex organ. The use of brain imaging techniques allows for discovery without the use of invasive surgical procedures. Now used throughout the globe‚ these techniques have matured dramatically in the last century. With its roots in the early twentieth century using low-tech devices‚ brain imaging has evolved dramatically

History and Science Behind MRI: Open or Closed Case? Magnetic Resonance Imaging (MRI) has been called one of the most comprehensive and efficacious diagnostic imaging modalities in medical history. It became a viable clinical technique in 1982 and during its relatively short lifetime has become the primary imaging modality for investigations of the brain‚ spinal cord‚ spine‚ cancellous bone‚ and joints. It is widely used for the identification and staging of tumors‚ investigations of large

Magnetic resonance imaging (MRI) is a type of scan that produces detailed images of the inside of the body using radio waves and strong magnetic fields without using radiation. An MRI scanner is a large tube that contains powerful magnets. During the scan‚ you lie inside the tube. Almost any part of the body can be examined using an MRI‚ including the brain and spinal cord‚ bones and joints‚ heart and blood vessels‚ internal organs‚ and breasts. MRI scans are safe and painless. Almost everyone
