    Abstract: Disclosed is a counterbalance system for moving a payload and a method for counterbalancing the payload. The system and method comprise a resilient member that is in communication with the payload to be moved and two resilient members that are in communication with either end of the first resilient member. An actuator is in communication with the first and third resilient members and a payload arm, attached to the payload, is in communication with the first and second resilient members. The resilient members may be compressed and relaxed during movement of the actuator and the payload arm so that energy may be transferred between the system and the payload to counterbalance the weight of the payload.

    Abstract: An actuator for moving an ultrasound transducer has a main body configured to be positioned adjacent to a target region of interest to be examined; and, a motor mounted on the main body. The motor is configured to have an ultrasound transducer connected thereto to simultaneously translate and rotate the ultrasound transducer to perform a compound scan of the target region of interest when the ultrasound transducer is connected to the motor. An ultrasound device has an ultrasound transducer movably mounted on the actuator. The actuator requires only single motor to effect both translation and rotation of the transducer thereby simplifying operation and providing a more compact device.

    Abstract: Disclosed is a modular base link for use in a counterbalancing arm. The base link includes two base plates and four connection points. Two stabilizing members are connected to and extend between the base plates. Two resilient members, one of which is hingeably connected to and in communication with the two connection points, the other resilient member is hingeably connected to and in communication with the other connection points. The connection points are eccentrically and orthogonally disposed relative to each other. The resilient members are sufficiently resilient to permit movement of the base plates relative to each other so as to counterbalance the arm when a load is applied to either base plate.

    Abstract: A method for registering ultrasound (US) and computed tomography (CT) images, comprising: receiving US and CT images representative of a body portion comprising blood vessels and an initial approximate transform; enhancing the blood vessels in the US and CT images, thereby obtaining an enhanced US and CT images; creating a point-set for a given one of the enhanced US and CT images; determining a final transform between the point-set and the other one of the enhanced US and CT images using the initial transform; applying the final transform to a given one of the US and CT images to align together a coordinate system of the US image and a coordinate system of the CT image, thereby obtaining a transformed image; and outputting the transformed image.

    Abstract: 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 a vessel enhancement algorithm to derive two corresponding enhanced images. The enhanced images can undergo a registration process based upon minimizing a mean-square-difference metric to derive an enhanced rigid transform, which represents a transform that maps the first enhanced image onto the second enhanced image. The two enhanced images are seamlessly combined via a blending process (via the use of a distance transform based weighting of the voxel values) to derive an output image.
