Reflecting the latest ARRT® content specifications, Radiographic Image Analysis, 6th Edition provides a guide to evaluating and adjusting images to produce diagnostic-quality radiographs. It helps you to identify the error in positioning or technique that may have caused a poor image, then shows how to correct the problem, so you can reduce the need for repeat radiographs. Each projection includes an optimal radiograph along with examples of unacceptable images. Written by radiology expert Kathy McQuillen Martensen, this text builds your critical thinking skills and helps you prepare for success on the ARRT certification examination.Chapter objectives, key terms, outlines, and summaries reinforce the most important material.Image analysis g

Simulated process printing is an intricate, high-quality method transforming the garment and screen printing industry. By enabling the replication of detailed, photorealistic images on textiles, it has significantly broadened the possibilities for fashion and textile design.

Screen printers are usually given very low-resolution and low-quality pictures and designs downloaded directly from websites for production. These images are, however, not sufficient for direct reproduction because web graphics are designed to be a size as small of a file size as possible. The reason for this is that this way, the web page, the images are lifted from, has a faster loading speed. Such images are then more than often have to re-drawn with the help of a vector program, for example, Adobe Illustrator or similar software. Or they are exposed to a number of Photoshop filters in order to try to enhance them, or sometimes both.
