The three separate volumes of the first edition, each designed to stand alone, have been combined into a single volume. Several chapters have been consolidated and additional information added, specifically in the ares of treatment planning, electronic charting, CT stimulation, dose distribution, and education. Pedagogical features, designed to enhance comprehension and critical thinking, are incorporated into each chapter. Elements include chapter outlines, key terms, and a glossary that includes significant terms from both editions. Of particular note are the Review Questions and Questions to Ponder at the end of each chapter.
