Some applications of holography to medical assessment. Part II.

This is the second and final part of the article begun in the previous issue. The same format as before has been followed-the main article describes the techniques of holography used in the Department of Medical Photography at the Royal Sussex County Hospital, while the tutorial which follows explains the physical concepts necessary to full understanding of the method. On this occasion the author discusses the use of holography in volumetric assessment of tumours revealed by CAT scan pictures, analysis and storage of dental models, together with the equipment involved and operating technique. Photographic materials and processing are described and suggestions for future applications of holography in medical assessment discussed.
