An embodiment of the invention provides a method and apparatus for registering two medical images with one another. A first medical image including a representation of a biological organ of a subject or for a population is obtained and the surface of the organ is identified in the first medical image. The identified surface is then used to construct a 3D geometric surface model of the organ. The geometric model is used to derive a motion model that incorporates information on the physical material properties of the organ and external forces that cause the organ to move and deform. A second medical image including a representation of the organ of the subject (or another subject, in the case that the first medical image is an atlas image) is obtained and an alignment is determined between a first surface normal vector field for the organ surface, derived from the geometric model, and a second surface normal vector field for the organ surface, derived by filtering the second medical image. The alignment accommodates deformation of the geometric model in accordance with the motion predicted by the motion model. The first and second medical images can then be registered with one another based on said determined model-to-image vector alignment (MIVA).

Devices and methods are provided for applying vacuum near to devices for delivering treatments to tissue adjacent a body cavity, effective to draw adjacent tissue near to such devices and to enhance treatment of the tissue. Body cavities include natural body cavities and cavities remaining after removal of tissue such as cancerous tissue. A device may include an inner balloon assembly with an inflation conduit. A sheath assembly having a fluid-permeable sheath wall may enclose the inner balloon assembly. Vacuum applied to the space between the sheath and the inner balloon is useful to draw tissue into contact with the device, improving treatment effectiveness. Methods for treating tissue with such devices and systems are also provided. Treatments may include providing radioactive material for radiation treatment, providing chemotherapeutic material for chemotherapy, providing thermal treatment, and combinations thereof. Systems may include devices of the invention and a vacuum source.

Provided is an inverted pendulum mobile vehicle such as a single-passenger coaxial two-wheel vehicle which is capable of turning with a small turning radius without causing discomfort to a rider or a vehicle occupant or causing a cargo or the like on the vehicle from shifting or falling off from the vehicle. The vehicle comprises a wheel supporting frame (12), a body frame (12) supported by the wheel supporting frame so as to be rotatable around a vertical axial line and carry a rider and or a cargo and a body coupler (52, 78, 70) that couples the body frame relative to the wheel supporting frame in a prescribed dynamic positional relationship. Thereby, even when the wheel supporting frame undergoes a rapid yaw movement either while traveling in a fore-and-aft direction or remaining stationary, the body frame that carries a vehicle occupant or a cargo is allowed to follow the yaw movement of the wheel supporting frame at a slower angular speed and / or acceleration / deceleration so that the vehicle occupant is prevented from experiencing discomfort and the cargo is prevented from shifting on the body frame or falling off from the vehicle.

A process cartridge detachably mountable to the main body of an image forming apparatus includes an electrophotographic photosensitive drum, at least one process device for acting on the drum, a cartridge frame holding the drum and the process device and exposing a portion of the drum, a shutter member provided for movement between a position to protect and a position to permit exposure the of the drum, and a shutter opening and closing link mechanism for moving the shutter member in operative association with the opening and closing operation of an openable and closable door when the process cartridge is mounted on the cartridge mounting portion of the main body of the image forming apparatus.

A visual tag having an imprinted image, a processor for calculating a response string corresponding to the content of the imprinted image and a challenge string, and a changeable screen to display the response string in machine-readable symbols. An authentication device reads the displayed symbols, and authenticates the displayed contents corresponding to the challenge string. The challenge string is generated either according to a random generator within the authentication device, or according to a real-time clock. A plurality of tags or objects can be authenticated and spotted within an image. The tag can also authenticate inputted messages and credentials.
