A Review on Image Processing Applications in Medical Field

The digital image processing involves the following steps[2]. * Image Acquisition: It is a basic step which involves capturing images through sensors and various image modalities and is represented by a matrix. * Image Enhancement: It is a fundamental supporting aid for reviewing atomic region in MRI and Ultrasound in medical field by decreasing noise and used to enhance visual representation of an image. * Correction/manipulation of color within an image: DIGITAL IMAGE PROCESSING ADVANTAGES IN MEDICAL APPLICATIONS: * Digital data is non changeable and always retains its originality; irrespective of how many times the data is reproduced. * Digital processing is a powerful tool to the doctors that moderate the search for representative images. * Once the image is acquired then immediately it displays. * Physicians can easily interpret the enhanced/intensified images. * It quantifying the changes over time. * Quick comparisons of images can be done. Stereoscopic technology aid the medical and clinical field in improving the accuracy of surgery and operational requirements. with reduction in operation time and assures patient safety with the help of realistic depth perception of 2D imaging technology [6]. A few signs for performing electrocardiography incorporate suspected pulmonary embolism, fainting or collapse, seizures, cardiac stress testing, atrial flutter.
