The design and implementation of an online guide system were presented for patients. Thesystem offers a website that makes it easier for patients, or any ordinary visitor to diagnose their diseaseby simply uploading their MRI image, the website also assists the patient in determining the doctor theyneed to see, and finding the nearest hospital or blood bank. To build the website, SQL Server, MATLAB, and Adobe Dreamweaver were utilized. The rapid increase in digital images produced in hospitals using medical imaging techniques such as X-Ray, CT scans, MRI, and ultrasound has increased the demandfor efficient image retrieval systems. Personal description, and annotation of each image in a large databaseusing text-based indexing (also known as the Metadata approach) is time-consuming, and impractical,making Content-based Image Retrieval (CBIR) a better option. CBIR system proposed returns results basedon visual features of the image, such as color, texture, and shape.
