A computer-implemented method for combining two 3-dimensional ultrasound images of a patient's body part containing blood vessels into a single 3-dimensional ultrasound image of that body part with a greater field of view. Blood vessels within the body part are used for registration. The two ultrasound images are preprocessed using... The University Of Western Ontario
A counterbalancing gimbal joints and/or a counterbalancing a load on a gimbal joint
Disclosed is a counterbalance apparatus, and a method for counterbalancing using an apparatus, having a center of motion that is internal or external to the apparatus. The apparatus and method are adapted to support a payload, having a load vector applied in a direction of the vector or gravity, that... The University Of Western Ontario
A counterbalance apparatus and/or supporting a load
A counterbalance apparatus for supporting a load includes a base, a load bearing arm, a toggle linkage, and first and second resilient members for applying a force to the load bearing arm. The load bearing arm has pivot points forming a parallelogram linkage, and is adapted to support the load... The University Of Western Ontario
The present disclosure provides a navigation method and system which does not require a remotely located tracking system, or additional targets or other devices to be installed on the patient or object being tracked. The system uses one flexible component in physical contact with the patient/object and measures relative position... The University Of Western Ontario
Reactor and multifunctional riser and downer simulator incorporating the same
A reactor comprises a reactor vessel defining a confined reactor volume, a support assembly extending about a periphery of the confined reactor volume, a basket positioned within the reactor vessel and supported by the support assembly, the basket having an interior surface and an exterior surface, a downflow zone being...
