ing of the existing x-ray depart nent at St. Ann's Hospital required much planning and careful consid- eration on the part of the hospital personnel. B. O. Martenson, Gen. eral Electrical Engineer Radiation Physicist and x-ray Technologist arrived in Juneau from Seattle on September IA, started work inn mediately and finished his ob- jective on October IA. B. O. Mar tenson left for Seattle by plane the following day.
 During the five weeks of Mar tensons stay at St. Ann's Hospital the following x-ray equipment was installed: A General Electric 200 milliampere four-tube Kenotron, oil-immersed high voltage switch and transformer with mobile Gen. tralinear Control, including all necessary accessories; the last word in X-ray equipment"
 The above mentioned X-ray gen. orator was placed at the side rail of the combination photographic and Microscopic table, and shock proof high voltage cables were used to conduct the energy to the radio graphic and microscopic X-ray tubes, Stretcher or bed patients can be taken to the rail side of the X-ray table and photographed with out necessitating the transfer of the patient to the table.
 X-Ray Table
 The X-ray table, the latest model cbtainable is powerful, quiet motor drive unit. The motive power for elevating or lowering the table top is applied to both sides of the table through two sets of gears, one to each sector, thus obviating any twisting action of the table top and assuring perfect alignment.
 The gears, which extend from the motor housing to actuate the sup porting sectors, are enclosed within dustproof housing which insures long, trouble-free operation. The ample power of the heavy-duty motor provides for easy handling of the heaviest patients. An efficient braking system brings the table to stop at any desired point without "coasting" or vibration. Automatic stops are provided at the extreme vertical and Trendelenburg po- sitions.
 Ideal for Fluoroscospy, exceptional convenience and flexibility are pro- vided for microscopic procedures with this "last word" in X-ray tables. The operating field is clear of all Instructions and the screen can be positioned accurately for viewing the lung apices without dis comfort to the patient. The fluor- cscopic tube and screen move in unison, with the tube focal spot |centered to the screen. Two sets of Microscopic shutter controls are mounted on the screen support and che can direct all movements of the screen and tube with one gloved hand while the other is free for pal patton or again both hands can be used for palpation and adjustment of fractures. Every facility is pro- vided for simplicity of operation in the darkened room.
 Microscopic Vision
 The travel of the enclosed fluoroS- copic tube permits microscopic vis- ion anywhere in an area 52 by P inches d36 by 56 cm) on the table top, in all positions from vertical to Trendelenburg. The design of the screen staging allows free and easy movement of the screen and tube unit regardless of whether the pa tient is in a vertical, angular, or horizontal position. All positions of the screen staging and tube unit |are self retaining.
 Potter -Bucky Diaphragm has 'un- usually wide latitude. The built-in General Electric Potter -Bucky dia- phragm is a thoroughly-tested de- sign which includes new operating mechanism and a new type grid. The grid's construction is such that one can successfully employ much greater variations in Potter -Bucky diaphragm technics than was pos sible with its predecessors. This high-speed type unit is magnetically interlocked so that the grid is set in motion when one steps on the foot switch or press the push-button switch of the x-ray unit; the grid in turn starts the x-ray timer, and the exposure begins, and when the predetermined exposure time is completed, the K-ray is turned off automatically. Grid travel time is selected by means of an easy-to-read conveniently-1ocated calibrated dial. Despite the extremely small patient film distance movement of the Pot ter -Bucky diaphragm along the length of the table is free and easy, unique system of long roller-bear- ing supports eliminates binding regardless of the patients weight, or the amount of compression applied
