Abstract: Systems and methods for visualization and interactive navigation of virtual images of internal organs are provided to assist in medical diagnosis and evaluation of internal organs. In one aspect, an image data processing system (105) includes an image rendering system (111) for rendering multi-dimensional views of an imaged object from an image dataset (106) of the imaged object, a graphical display system (112) for displaying an image of a rendered view according to specified visualization parameters, an interactive navigation system (107) which monitors a user's navigation through a virtual image space of a displayed image and which provides user navigation assistance in the form of tactile feedback by a navigation control unit (115) operated by the user, upon an occurrence of a predetermined navigation event.

Abstract: A system and method are provided for generating a three-dimensional visualization image of an object such as an organ using volume visualization techniques and exploring the image using a guided navigation system that allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order, for example, to identify polyps, cysts or other abnormal features in the visualized organ; where imaging data sets are acquired using conventional two-dimensional scans of the object in both a supine and prone orientation, and correspondence between the respective data sets is determined to permit jumping from one visualization orientation to the other while remaining at the same virtual location within the organ.

Abstract: A paint roller tray is provided adapted for use with a flexible paint container. In one embodiment, the tray is provided with an orifice in a side wall portion that can be connected by way of a conduit to the paint container. By merely lifting the paint container above the level of the tray, paint flows into the tray in a completely enclosed path, whereby drips or spills are precluded. In another embodiment, a unitary package is provided that combines a roller tray with container means to hold a quantity of liquid paint, and conduit means to direct paint from the container into the tray portion of the apparatus. The apparatus is preferably disposable.
