evice has been materi-ally improved by the construction of ametallic funnel through which all sec-ondary and side radiation is effectivelyheld back. T he gray appearance ofthe fluoroscopic image which very oftenmakes the fluoroscopic examination ofheavy patients difficult or impossible iseffectively checked. Examination of this shutter reveals that a decidedly bet-ter and clearer fluoroscopic image canbe obtained with this improved shutterand shield. The screen itself is abso-lutely flexible. It can be placed in anydesired position and the area coveredby the fluoroscopic tube and shield islarge enough that the entire trunk ofa patient can be examined fluoroscopi- cally without shifting the patient. For radiographic work the screenarm can be removed. After changingthe high tension switch the radiographictube can be used above the table andall radiographic examinations feasiblewith the thirty ma. radiator type Cool-idge tube can be made accurately andsecurely with a minimum loss of time

197 involved in changing from one positionto the other or from the fluoroscopic tothe radiographic setting. The floorspace required for this unit is ten andone-half by four feet. If the unit isrequired only for fluoroscopic work itcan be connected to an existing houseline, but if the thirty ma. radiographictube is to be used for radiographicwork a line with a carrying capacityof about thref k.w. must be provided. The x-rays, with full justification,have become known as a positive meansfor diagnosis and their successful ap-plication depends to a very large extenton the design and development of ap-paratus applicable to the great varietyof examinations which the medicalpractitioner is required to make. Thus,for establishing accurate and correctdiagnosis a number of different methodsof applying the x-rays must be feasible.As an example, for the examination ofthe visceral organs, especially with re-gard to their position and mobility,there is reouired a fluoroscopic devicewhich enables on
