Provides Positioning System For Breast Cancer Research
Researchers at Dartmouth
College, Thayer School Engineering, are seeking new ways to
diagnose breast cancer.
Using the diffuse
near infrared tomography, researchers hope to detect pre cancerous
changes in breast tissue. To accomplish this, they needed
to coordinate an array of fiber optics in a radial pattern
around the breast.
The system designed by Velmex includes
16 small UniSlide® positioners spaced in a radial pattern
to position the fiber optics. The entire array is also movable
in a vertical direction using a Velmex BiSlide® system.
A control system provides for synchronized,
simultaneous movement of the 16 linear positioners using low
voltage step motors. A separate control is provided for vertical
motion. Joystick operation is standard with computer control
Used for Fiber optic Manufacturing
Co in Finland is a leading manufacturer of optical fiber draw
towers. Sondek Oy. provide them with this instrument called
Pullman that allows the operators to control the draw tension
of the bare, hot fiber (dia. = 0.125 mm) while the fiber is
moving at speeds of 1000 m/min or more. The apparatus uses an
A40 Series (knob facing camera) and A60 Series (on edge, in
back). The Pullman is clearly improving the yield and provides
better quality control of the fiber.
