Yes. Kaplan.edu and Rochester Institute of Technology are two reputable ones. However, check with your state-- a degree, online or not, may not be enough to get a license to work. Some kind of residency (like an apprenticeship) is usually required in addition to a certification program or degree. This area of specialty is extremely narrow and the schools that offer such a program are few and far between. However, Florida Hospital College of Health Science offers an online bachelor's degree and Pima Medical Institute offers an associate''s degree in this area.
