Hey, I hope you are doing great? In this video, we will talk about medical imaging, we will see the analog and digital signs, and discuss the concepts of pixels, voxels, and matrix. Finally, we will see some characteristics of the medical image including: spatial resolution, contrast, and noise. and we will see the representation of the image.
