A brief description of the setup of an inexpensive densitometric analysis system is provided. This system uses a software package and scanner that can be obtained for a total of less than $1000 and that can be operated by any Macintosh computer, including a MacPlus. In the event that a scanner is already available, the software itself can be obtained for approximately $399. Several comparisons are presented of data obtained with this system, data obtained by other analytical methods and data obtained with more expensive, dedicated densitometric systems. These comparisons demonstrate the usefulness and accuracy of this system.
