Pixels and Matrix - Video Lesson

This lesson is about pixels and the digital matrix in CT imaging. CT was digital before digital was cool. CT has always been a digital technology. Here's how it works. The information from the detector array is divided into thousands of tiny little squares called pixels. Each pixel represents one small part of the CT image. All pixels together form what we call the image matrix. The word pixel is actually an acronym that stands for picture element because that's exactly what a pixel is. It's one tiny part or elements of a larger picture. Pixels in a matrix are kind of like the tiny tiles in a mosaic. Here's an example of a mosaic. When you zoom in, you can see that tiny tiles make up the larger image. And that's just like picture elements or pixels inside of the digital matrix. Nor
