(1) D O P P L E R U L T R A S O N I C E V A L U A T I O N O F CEREBROVASCULAR DISEASE by ROBERT W. BARNESand MICHAELR. WILSON. 196 pp. $25.00. (2) D O P P L E R U L T R A S O N I C E V A L U A T I O N O F PERIPHERAL ARTERIAL DISEASE by ROBERT W. BARNESand MICHAELR. WILSON. 296 pp. $25.00. (3) D O P P L E R U L T R A S O N I C E V A L U A T I O N OF VENOUS DISEASE by ROBERT W. BARNES, HENRY E. RUSSELL and MICHAELR. WILSON. 251 pp. $25.00. All three books for $60.00. Audio-Visual Center, University of Iowa, Iowa City, Iowa 52242 (1977). Each of these books which comes accompanied by a cassette recording and stethoscope headset for stereophonic listening is a programmed learning course in its respective field. After an introductory chapter to the subject, the three books describe, in very similar chapters, the ultrasonic velocity detector and then proceed after a description of normal anatomy and the relevant normal ultrasonic examinations, to a description of the clinical application of these techniques in their respective fields. These latter demonstrations are accompanied, where appropriate, by stereophonic recordings of the corresponding Doppler audio signals. The three courses are designed to give a comprehensive overview of their respective subjects to persons with little or no preceding medical or ultrasonic expertise. Under these circumstances, as is always the case with programmed learning, persons with prior knowledge may find it somewhat tedious that each fact that is enunciated is immediately followed by a rather elementary question to determine whether the reader really understood what he read. When, however, the subject matter deals with less elementary matters this method of reinforcement may be found to be useful and of course the expert can always skip those sections which be believes he well understands. The authors undoubtedly succeed in providing to the reader a most comprehensive review of Doppler technology as it is currently practised in the clinical setting. Even though the reader may feel at times that the material contained in these three courses could readily be condensed into a much smaller span of written text there is no doubt that the repetition involved in programmed learning and that the accompaniment of the Doppler signals being described both by an audio and also a video display in the text insures that any reader with the patience to work through the three courses will emerge with a
solidly based foundation in the clinical use of ultrasonic Doppler technology. Each book ends with a summarizing chapter describing the current state of the art in their respective fields and largely based upon the authors' own work at the University of Iowa. While the critical reader might wish for somewhat broader coverage the workers at the University of Iowa have been so pre-eminent in the development of the clinical applications of ultrasonic Doppler techniques that the reader can have little quarrel with such a description of their own work and opinions. These books should be made mandatory reading for any technologist or physician who intends to start using Doppler techniques in a clinical setting and will provide them with the basic information that they will need for practising such techniques in a responsible fashion. The books are printed by the photographic technique and are remarkably free of typographical errors save for the misplacement of the exponents in Poiseuille's equation. There are numerous simple but adequate illustrations including simplified video displays of the audio signals recorded on the tape and illustrating the Doppler signals under discussion. The stereophonic tapes are of excellent quality even though that supplied to this reviewer had an annoying background of partially unerased conversation. The absence of an index will be regretted by those who wish to refer to specific points illustrated in the text. In summary these are three programmed learning texts that can be unreservedly recommended to all novices interested in using ultrasonic Doppler technology in a clinical setting and which will even be beneficial as a source of review and discussion for established workers in the field.
