During the last decade, echography has become as useful for the diagnosis of pathologic processes in soft tissues as the x-ray film became for bony structures eighty years ago. The production of the contact B-scan by Bronson and Turner has contributed greatly to the popularity of clinical echography. The advantages are obvious. The instrument is small and relatively inexpensive; it can be used without a water bath; and it gives echographic sections of the tissues with reasonably good resolution. In this little monograph, the authors describe the use of the instrument, outline its usefulness, and delineate its limitations. Anybody who has or plans to purchase the Bronson-Turner instrument should buy this booklet. While contact B-scan echography cannot compete in sophistication and refinement with the presently available immersion B-scan or the quantitative A-scan machines (for instance, no tissue differentiation is possible), it could serve
