"First Steps in Eliminating the Need for Animals and Cadavers in Advanced Trauma Life Support®", Christoph Kaufmann, Scott Zakaluzny, Alan Liu. Published in Medical Image Computing and Computer-Assisted Intervention (MICCAI), Lecture Notes in Computer Science 1935 Springer 2000 ISBN 3-540-41189-5, pp. 618-623, 2000.
Abstract: The Advanced Trauma Life Support® course is designed to provide for optimal initial resuscitation of the seriously injured patient. The surgical skills component of this course requires the use of cadavers or anesthetized animals. Significant anatomical differences and ethical issues limit the utility of animals. The cost and difficulty in procuring cadavers makes widespread use of this option impractical. A combination of mannequin and computer-based surgical simulators is being developed to replace these animals and cadavers. The first of these simulators, a pericardiocentesis trainer, is complete.
"A computer-based simulator for diagnostic peritoneal lavage", Alan Liu, Christoph Kaufmann, Thomas Ritchie. Medicine Meets Virtual Reality 2001. Westwood J. D., et al., eds. IOS press, 2001. pp. 279-285.
Abstract: Diagnostic peritoneal lavage (DPL) is an emergency diagnostic procedure performed when intra-abdominal bleeding secondary to trauma is suspected. This procedure is part of the surgical skills section of the Advanced Trauma Life Support course. DPL is traditionally taught using anesthetized animals or cadavers. For reasons described below, these alternatives are not ideal. We have developed a computer-based diagnostic peritoneal lavage simulator. Our system addresses the shortcomings of the traditional method. We have used our system to teach ATLS®. Preliminary results suggests that our system is effective.
"An architecture for simulating needle-based surgical procedures", Alan Liu, Christoph Kaufmann, Daigo Tanaka. Medical Image Computing and Computer-Assisted Intervention (MICCAI), Lecture Notes in Computer Science 2208 Springer 2001, ISBN 3-540-42697Sat, January 27, 2007 11:47 PMLOCKQUOTE>
Abstract: Many surgical procedures use cannulas, guidewires, and catheters in the treatment of life threatening conditions (e.g. cardiac tamponade and tension pneumothorax), or for diagnosis (e.g. diagnostic peritoneal lavage). Simulator development is costly in time and resources. Most computer-based trainers are procedure-specific. Each trainer uses a different hardware configuration. The cost of using multiple simulators for teaching is prohibitive. A result is decreased acceptance of simulation for teaching. A generalized software architecture has been developed that simplifies the process of constructing trainers for needle-based surgical procedures. Different procedures use the same hardware platform. The architecture has been used to develop two trauma simulators. A third simulator is currently being developed using this architecture.
"The Evaluation of the Color Blending Function for the Texture Generation from Photographs", Daigo Tanaka, Alan Liu, Christoph Kaufmann. Medical Image Computing and Computer-Assisted Intervention (MICCAI), Lecture Notes in Computer Science 2208 Springer 2001, ISBN 3-540-42697-3, pp. 1199-1200, 2001.
Abstract: Mass-casualty triage simulation requires the realistic depiction of wounds and other signs of external injury on victims. Texture maps permit images of actual wounds to be rendered over computer models. Several images may be required to depict extensive injuries. Seamlessly combining these images requires an appropriate blending function. This paper compares two functions for their ability to create visually appealing integrations.
