Common Phantoms

Séances, clairvoyance, and telepathy captivated public imagination in the United States from the 1850s well into the twentieth century. Though skeptics dismissed these experiences as delusions, a new kind of investigator emerged to seek the science behind such phenomena. With new technologies like the telegraph collapsing the boundaries of time and space, an explanation seemed within reach. As Americans took up psychical experiments in their homes, the boundaries of the mind began to waver. Common Phantoms brings these experiments back to life while modeling a new approach to the history of psychology and the mind sciences. Drawing on previously untapped archives of participant-reported data, Alicia Puglionesi recounts how an eclectic group of investigators tried to capture the most elusive dimensions of human consciousness. A vast though flawed experiment in democratic science, psychical research gave participants valuable tools with which to study their experiences on their own terms. Academic psychology would ultimately disown this effort as both a scientific failure and a remnant of magical thinking, but its challenge to the limits of science, the mind, and the soul still reverberates today.

The purpose and subject of this book is to provide a comprehensive overview of all types of phantoms used in medical imaging, therapy, nuclear medicine and health physics. For ionizing radiation, dosimetry with respect to issues of material composition, shape, and motion/position effects are all highlighted. For medical imaging, each type of technology will need specific materials and designs, and the physics and indications will be explored for each type. Health physics phantoms are concerned with some of the same issues such as material heterogeneity, but also unique issues such as organ-specific radiation dose from sources distributed in other organs. Readers will be able to use this book to select the appropriate phantom from a vendor at a clinic, to learn from as a student, to choose materials for custom phantom design, to design dynamic features, and as a reference for a variety of applications. Some of the information enclosed is found in other sources, divided especially along the three categories of imaging, therapy, and health physics. To our knowledge, even though professionally, many medical physicists need to bridge the three catagories described above.

In this book, Barbara Ellison and Thomas B. W. Bailey lay out and explore the mystifying and evanescent musical territory of 'sonic phantoms': auditory illusions within the musical material that convey a 'phantasmatic' presence. Structured around a large body of compositional work developed by Ellison over the past decade, sonic phantoms are revealed and illustrated as they arise through a diverse array of musical sources, materials, techniques, and compositional tools: voices (real and synthetic), field recordings, instrument manipulation, object amplification, improvisation, and recording studio techniques. Somehow inherent in all music--and perhaps in all sound--sonic phantoms lurk and stalk with the promise of mystery and elevation. We just need to conjure them.

Featuring an abundance of illustrations, succinct, straightforward explanations and clear, step-by-step guidance, it includes the fundamental physics, technical principles, and imaging strategies and procedures involved in CT scanning. Over the course of twenty four, concise modular chapters, CT at a Glance covers all the bases for entry-to-practice students, including: The basic physics underlying CT scanning State-of-the-art multi-slice technologies Data acquisition strategies Equipment components—their functions and applications Image reconstruction and image quality control CT dose and dose optimization procedures Quality control fundamentals CT at a Glance is an indispensable learning resource for students in medical imaging technology courses, including those covering radiography, nuclear medicine, and radiation therapy, as well as for biomedical engineering technology students.

This book presents cutting-edge research and developments in the broad field of medical, biological engineering and computing. It gathers the second volume of the joint proceedings of the Mediterranean Conference on Medical and Biological Engineering and Computing (MEDICON) and the International Conference on Medical and Biological Engineering (CMBEBIH), which were held together on September 14-16, 2023, in Sarajevo, Bosnia and Herzegovina. Contributions report on innovative research and practices in molecular biology, tissue engineering and biotechnologies, covering not only medical but also industrial applications. Further, they describe advances in health technologies and medical devices, telemedicine, and robotic applications in clinical medicine and rehabilitation.

Phantom limb pain is one of the most intractable and merciless pains ever known—a pain that haunts appendages that do not physically exist, often persisting with uncanny realness long after fleshy limbs have been traumatically, surgically, or congenitally lost. The very existence and “naturalness” of this pain has been instrumental in modern science’s ability to create prosthetic technologies that many feel have transformative, self-actualizing, and even transcendent power. In Phantom Limb, Cassandra S. Crawford critically examines phantom limb pain and its relationship to prosthetic innovation, tracing the major shifts in knowledge of the causes and characteristics of the phenomenon. Crawford exposes how the meanings of phantom limb pain have been influenced by developments in prosthetic science and ideas about the extraordinary power of these technologies to liberate and fundamentally alter the human body, mind, and spirit. Through intensive observation at a prosthetic clinic, interviews with key researchers and clinicians, and an analysis of historical and contemporary psychological and medical literature, she examines the modernization of amputation and exposes how medical understanding about phantom limbs has changed from the late-19th to the early-21st century. Crawford interrogates the impact of advances in technology, medicine, psychology and neuroscience, as well as changes in the meaning of limb loss, popular representations of amputees, and corporeal ideology. Phantom Limb questions our most deeply held ideas of what is normal, natural, and even moral about the physical human body.
