The textbook "Alternative Breast Imaging" from Springer offers a comprehensive examination of innovative imaging techniques for breast examination. Over the past three decades, medical imaging has significantly advanced with the use of computed tomography (CT), magnetic resonance imaging (MRI), and improvements in X-ray and ultrasound technology. This book focuses on four novel, model-based approaches to breast imaging: MR elastography, electrical impedance spectroscopy, microwave imaging spectroscopy, and near-infrared spectroscopic imaging. It provides both theoretical and practical insights into these technologies and their application to enhance breast cancer diagnosis. The chapters are structured to first explain the theoretical foundations of each modality, followed by implementation and results chapters. The book concludes with a discussion on statistical methods for image analysis that are relevant to these alternative imaging techniques.
