Bringing the power of virtual instrumentation to the biomedical community.
Bringing the power of virtual instrumentation to the biomedical community.
Virtual instrumentation allows medical researchers and practitioners to combine the traditional diagnostic tools with advanced technologies such as databases, Active X, and the Internet. In both laboratory and clinical environments, users can interact with a wealth of disparate systems, facilitating better, faster, and more informed decision making. Virtual Bio-Instrumentation: Biomedical, Clinical, and Healthcare Applications in LabVIEW is the first book of its kind to apply VI technology to the biomedical field.
Both students and practicing professionals will appreciate the practical applications offered for modeling fundamental physiology, advanced systems analysis, medical device development and testing, and even hospital management and clinical engineering scenarios.
