An ultrasonic wave generating device includes a housing to seal an inside of a cartridge; a transducer to generate ultrasonic waves and disposed in the housing; a rotational force applying unit to receive a rotational force from an outside of the housing and perform a rotational motion; a conversion unit to convert the rotational motion of the rotational force applying unit into a rectilinear motion and provide the rectilinear motion to the transducer; and a controller to control an ultrasonic wave generating operation of the transducer.

An outer case for an ultrasonic probe that houses a module of the ultrasonic probe is provided. The outer case includes a grip case gripped by a user and a head case that engages with the grip case. The grip case has a first engaging portion where one or a plurality of convex portions are disposed. The head case has a second engaging portion where one or a plurality of depressed portions are disposed at positions where the one or plurality of depressed portions engage with the one or plurality of convex portions. The convex portion and the depressed portion are engaged to be locked.

Systems and methods of real-time augmented visualization of anatomical features are disclosed herein. The systems and methods can use concurrently collected and/or preexisting data regarding an anatomical structure to present an image of the anatomical structure to an operator in virtual space as overlayed in real space. The systems and methods can include acquiring image data from an anatomical structure of a subject. Visual image data of the subject can then be received, including non-rigid deformation of the subject. The device pose of the ultrasound device in real space can be determined using device pose data. Image pose of the image data can then be determined in virtual space. Then, a perspective pose of the image of at least a portion of the anatomical structure in virtual space can be mapped to the subject in real space.

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 is positioned distal to the center of motion. The apparatus includes a gimbal adapted to support the payload and allow for its rotational movement about the center of motion generating a load torque therefrom, and a resilient member adapted to engage the gimbal and supply a support torque to counterbalance the load torque. The method includes a step of supporting the payload with a gimbal adapted to allow rotational movement of the payload about the center of motion to generate a load torque therefrom, and a step of configuring a resilient member to engage the gimbal and supply a support torque to counterbalance the load torque.
