Abstract: A method of correcting errors in the output of an image detector is disclosed. The method comprises measuring an output signal (Vm) of a capacitor (Csh) holding a voltage corresponding to a signal detected by the image detector; comparing the value of output signal (Vm) to the value of the previously measured output signal (Vm?1) of the capacitor (Csh); calculating the error in the output signal (Vm) using a predetermined correction factor and the difference between the value of the output signal (Vm) and the value of the previously measured output signal (Vm?1); and providing a corrected output value (Vcrt) in accordance with the calculated error. Detectors, methods of calibrating detectors, image correction apparatus and guidance systems comprising the detectors are also disclosed.

Abstract: An automatic bone traction device for correction bone deformities is disclosed. The automatic bone traction device can include a main body, a step motor, a series of transmission gears, and connectors. In one implementation, the step motor operates at a speed of eight steps per second, and the series of transmission gears can step down the motion of the step motor to two revolutions per day. The generated driving torque is then transmitted to a bone distractor, such as a commercially available intermittent distractor. The automatic bone traction device is capable of activating the bone distractor continuously at a rate of two revolutions per day. Advantageously, a flexible shaft is used to connect between the transmission gear assembly and the bone distractor. The flexible shaft allows the main body of the bone traction device to be mounted away from the bone distractor at a convenient location for the user.
