Notes to Financial Statements
Subsequent Events [Text Block]	On July 1, 2012, we completed the sale of a 41% ownership interest of one of our consolidated joint ventures to our existing partner in that joint venture for $1.8 million.  After the sale, we will retain a 49% ownership interest in this joint venture. The result of this transaction will be our de-consolidation of this joint venture and our recording of the fair value of our remaining investment as a non-consolidated joint venture accounted for under the equity method.  On July 23, 2012, we completed our acquisition of a multi-modality imaging center, Orthopedic Imaging Center, LLC. located in Redlands, California, for cash consideration of $700,000.
