Alliance Imaging, Inc. (NYSE:AIQ), a leading national provider of outpatient diagnostic imaging and radiation therapy services, has named Richard J. Hall President of Alliance Oncology and Mark Carol, M.D., as Chief Medical Officer for Alliance. Both executives will join Alliance on November 3, 2008 and will report to Paul Viviano, Chairman of the Board and Chief Executive Officer.

"These appointments fill key positions that will support our business performance and strategic growth initiatives," said Viviano. "Rick and Mark are proven leaders who bring strong managerial skills as well as in-depth and industry-recognized expertise in health care. Their track record of success reinforces our vision of being the recognized leader in advanced medical imaging and radiation oncology, setting the standard for quality patient care, customer service and team member satisfaction."

Mr. Hall's extensive health care background includes more than 25 years experience in both the public and private sectors, including approximately four years as Senior Vice President of Business Development and Marketing for US Oncology, the nation's largest oncology services provider. US Oncology is affiliated with more than 1,200 physicians practicing in approximately 472 locations, including 91 cancer centers and radiation facilities in 39 states. Mr. Hall began his career with American Hospital Supply and has also held senior leadership positions with General Medical Corporation, McKesson Corporation, PatientKeeper and BrightStar Healthcare.

Mr. Hall earned a bachelor's degree in health care administration from Pennsylvania State University, and completed studies in the executive health care program at Duke University.

Dr. Carol is an industry veteran with more than 20 years experience in radiation oncology. Although he is a neurosurgeon by training, he followed his passion for research and innovation early in his career by founding and serving as President and Chief Technology Officer and eventually Chief Executive Officer of his own medical device company that developed and sold novel technology for use in neurosurgery and radiation therapy. In 1993, this company became known as NOMOS Corporation, where Dr. Carol pioneered the development and clinical application of intensity modulated radiation therapy (IMRT) and image guided radiation therapy (IGRT). Most recently, Dr. Carol served in an executive leadership position within Xoft.

Dr. Carol has published in the fields of radiation therapy and neurosurgery, holds patents in radiation therapy, neurosurgery and cardiology, and has been elected to honorary membership in the American Association of Physicists in Medicine. He recently was the inaugural recipient of the Ira Sohn Conference Foundation Prize in Pediatric Oncology, part of the Gotham prize, for his innovative ideas in the field of radiation therapy.

Dr. Carol earned a bachelor's degree as an Independent Scholar from Amherst College, an M.D. with distinction in research from the University of Rochester, and served his residency in neurosurgery and a fellowship in trauma at the University of Maryland.
