CV Imaging process

CV Imaging process

Cardiac imaging which refers to a non-invasive imaging of the heart by which the ultrasound, magnetic resonance imaging (MRI), computed tomography (CT) and nuclear medicine (NM) imaging with the PET. The image process is a form of signal processing for the input which is an image and the output may either be an image or the set of characteristics which are related to the image. It is mainly used in areas like multimedia, computing, remote sensing, image compression and retrieval. The main needs of image processing in the medicine are produced by an equipment’s which are composed of the pixels in which discrete brightness and colour values are assigned. Image processing techniques that were originally developed for analysing remote sensing data can be modified to analyse the outputs of medicinal imaging systems to get the best way of the advantage to analyse the symptoms of patients with the ease. It also has the helped the doctors to make the keyhole surgeries without opening the too much of the body. The main tasks performed by the image processing unit which are in the changing the density of dynamic range between the images, Colour correction and manipulating of colours with in a colour image, Zooming of images, generation of negative images, Contour detection and the area calculation of the cells of a biomedical image and construction of 3-D images from 2-D images. The principles of the image processing are in an image can be usually a function of the two spatial variables which represent the brightness at the Cartesian location. It also be defined as the array as a square pixels arranged in columns and rows. The computing processing is used for an image enhancement, segmentation, recognition and Transformation. In the image proceeding can be of two type’s Analog image, Digital image in an analog can be described by the spatial distribution of brightness that reflects a distribution of detected energy. Black and white images are required only in one gray level image. In Digital Images the digital image is discrete in both spatial and intensity domains. A discrete spatial location of the finite size with a discrete gray – level which is called a pixel. The CVI group partners with other divisions including cardiology, cardiothoracic and vascular surgery, transplant teams, and the Lucile Packard Children's Hospital to support personalized and comprehensive patient care. Cardiograph, single-photon emission computed tomography (SPECT), positron emission tomography (PET), cardiac magnetic resonance, and cardiac computed tomography can be used for anatomic and functional imaging of the heart. All 4 methods are subject to continuous improvement. The Echocardiography benefits from the more widespread availability of 3-dimensional are imaging, and strain rate analysis, and contrast applications to the image proceeding. SPECT imaging continues which provides very valuable prognostic data, PET imaging, on the other hand, which permits quantification of coronary flow reserve, a strong prognostic predictor of the patient’s body. Computed tomography imaging of heart mainly concentrates on the imaging of the coronary artery lumen and the plaque and has made the substantial progress regarding outcome data of the process. Cardiac (heart) imaging procedures which include: CT Coronary Angiography (CTCA), Coronary Artery Calcium Scoring, MRI Heart (Cardiac MRI). These tests are used to screen the heart disease, determine what is causing your symptoms and monitor your heart and find out if your treatment is working.
