The detection of liver (hepatic carcinoma) image protocol using Research Proposal

The detection of liver (hepatic carcinoma) image protocol using 64-MDCT. The effect of contrast injection technique, patient size and low dose parameters on the image quality - Research Proposal Example The use of CT in detection of the liver has been there for several years. Parameters that control radiation calculation are many. For example, the default solutions, and iteration parameters, are used in most problems. The process of detection using the 64-MDCT requires patients that have lesions that are surgically proven. These patients then will have to undergo through the triple phase 64-MDCT process. The patients will be observed independently. Later, a thorough evaluation of MR and CT imaging process is required. This is done on a lesion-by-lesion point. According to Hayat (2009), the reproductively, negative and positive values and sensitivity are then evaluated. The diagnostic accuracy of the method is assessed against the alternative free response characteristics analysis. The main objective of the project is to develop a simple methodology. This is where users can establish exposure factors that can be practical to patients. This includes the patients with different body weights. The method is used instead of, relying on the current approach of using default values based upon standard sized patient. They developed a simple mAs prediction equation to optimize radiation dose for all patient weight categories. The results showed that patient weight can be a good predictor of required dose. In addition, an agreement can be reached, at a certain noise level, to be acceptable. Moreover, the value could be increased for larger patients. The radiation dose reduction requires the lowering of kV or mA settings, Schoenberg (2007). This will, however, increase the noise when all other settings are kept constant. The mA settings are adjusted continuously until the best results are achieved. The reduction of tube voltage is done. This is a strategy of reducing the dose as the image quality is improved. The attenuation of calcium and iodine levels is increased at lower kV.
