Abstract

Biomedical imaging focuses on the capture of images for both diagnostic purpose and therapeutic purposes. These technologies utilize radioactive pharmaceuticals (SPECT, PET), x-rays (CT scans), ultrasound, magnetism (MRI), or endoscopy, OCT to assess the current condition of an organ or tissue and can monitor a patient over time over time for diagnostic and treatment assessment. Imaging has become a very important part in diverse fields of medical and laboratory research. Analysis of these different image types requires knowledgeable computerized quantification and visualization tools. Until recently, 3D visualization of images and quantitative observation could only be executed with help of expensive workstations and customized software. Today, much of conceptualizing and inspection can be executed on an inexpensive desktop computer equipped with the appropriate graphics hardware and software. In this review paper, we studied the concept of wiener filter and bilinear filter which help in denoising X-ray and MRI images. Besides this also studied about types of images and various domain of filtering, for example, spatial domain and frequency domain which will help in to carry out research. Image quality will be observed using PSNR and MSE parameters
