Patent number: 6449340Abstract: The present disclosure provides an adjustable collimator for collimating a beam of energy emitted from a focal spot of a beam source. The collimator is particularly intended for collimating an x-ray beam of a computed tomography scanner after the x-ray beam has passed through a patient being scanned. The collimator includes two elongated parallel plates arranged side by side to define a collimating slit between the plates. At least one of the plates is movably relative to the other plate for varying a width of the collimating slit. The collimator also includes a movable cam operatively arranged with respect to the at least one movable plate such that movement of the cam in a first direction causes the width of the collimating slit to increase, while movement of the cam in a second direction causes the width of the collimating slit to decrease.Type: GrantFiled: January 18, 2001Date of Patent: September 10, 2002Assignee: Analogic CorporationInventors: Andrew P.

Patent number: 6188743Abstract: In an improved computed tomography scanner drive system and bearing configuration, a gantry disk (30) is sheaved about its perimeter (65) such that the gantry is operable as a driven pulley rotatable about an object to be scanned. A motor (46) assembles mounted to a stationary frame (33) includes a similar sheaved drive pulley (80). A belt (64) tensioned between the drive pulley (80) of the motor assembly and the driven pulley of the gantry disk (30) transfers rotational motion of the motor to drive the gantry rotationally about the object. In a preferred embodiment, the belt comprises a V-belt or poly-V-belt (64), and the bearing comprises a wire bearing (59) located proximal to the gantry center of mass. In this manner, the present invention provides a simple and effective technique for driving the gantry about the object, providing sufficiently accurate angular positioning in a reliable and cost effective drive system. Various embodiments of an improved bearing system are also disclosed.Type: GrantFiled: July 26, 1999Date of Patent: February 13, 2001Assignee: Analogic CorporationInventors: Andrew P.

Patent number: 5982843Abstract: A computed tomography (CT) scanner includes an enclosure which forms a substantially sealed chamber around the rotatable disk carrying the radiation source and the radiation detectors. The CT scanner further includes an air conditioning system for controlling the temperature and humidity of the air inside the chamber. The air conditioning system can be a closed loop system whereby only air from inside the chamber is processed through the air conditioning system and no outside air is introduced to the chamber. Thus, the CT scanner can be operated in a wider range of environmental conditions. In an alternate embodiment, the air conditioning system can produce a positive pressure inside the chamber to prevent outside air from entering through openings in the enclosure. In this embodiment, the air conditioning system can include an input port in order to draw sufficient outside air to produce a positive pressure inside the chamber.Type: GrantFiled: October 10, 1997Date of Patent: November 9, 1999Assignee: Analogic CorporationInventors: Eric M.

Patent number: 5937028Abstract: In a computed tomography (CT) scanner, an X-ray shield is mountable to a gantry for absorbing randomly scattered X-ray radiation. The shield is rotatable with the gantry disk for regulating the emission of X-ray radiation near its source. The shield is preferably lined with an energy-absorbent material to provide safe energy levels in the environment external to the system. By minimizing the surface area of the shield, the present system results in significant weight reduction and ease of installation over prior shielding systems.Type: GrantFiled: October 10, 1997Date of Patent: August 10, 1999Assignee: Analogic CorporationInventors: Andrew P.

Patent number: 5769432Abstract: A wheel lock assembly for an in-line skate includes an axle assembly for supporting a skate wheel and defining an enclosed cavity, and an actuator assembly comprising an actuator member disposed in the cavity movable by a control member disposed externally of the axle assembly. The lock assembly further includes a lock pad assembly comprising a lock pad adapted to engage an inside surface of the skate wheel mounted on the axle assembly, a support beam extending from the pad inwardly through a portion of the axle assembly and into the cavity, and a spring urging the lock pad and support inwardly to bias a free end of the support against the actuator member. Manipulation of the control member causes movement of the actuator member in the cavity, to cause movement of the support, to cause radial movement of the lock pad selectively into and out of engagement with the skate wheel inside surface.Type: GrantFiled: December 13, 1995Date of Patent: June 23, 1998Inventors: Andrew P.
