Lossless compression is a method of reducing the size of image files without compromising any data or fidelity from the original image. This means that after the compression process, the resulting image retains all the pixel information and details of the original, making it an exact replica. As a result, any loss of quality, which can occur with lossy compression methods, is entirely avoided.

Understanding the context of other options clarifies why they do not apply. When discussing lossless compression, it is essential to recognize that it is designed specifically to prevent any alteration in image quality. The method distinctly maintains the integrity of the original file, ensuring that professionals, such as CT technologists, can rely on the accuracy of the images for diagnostics and analysis. Thus, lossless compression is instrumental in preserving high quality in precision medical imaging.
