A decision about which specific piece of screening or diagnostic equipment is best for a particular situation is dependent on many factors that must be weighed and evaluated by the person(s) making the decision. The information provided in this section is the opinion of NCHAM staff members and is provided to assist people in selecting equipment that is appropriate for their needs. Nothing here should be construed as an endorsement by NCHAM or any of its funding sources for one brand of equipment over another. This list is for information purposes only.
