Abstract:

The present invention discloses a method, apparatus, and article of manufacture for creating a report on a computer. In accordance with an embodiment of the present invention, one or more nodes of a decision tree are displayed to a user. Information about the displayed nodes are then received from a user. The information includes at least one selected node. The structured report is converted into a report based on the selected nodes. In another embodiment of the present invention, the structured report is stored in a database that is connected to the computer.

Abstract:

The invention relates to an acrylic alloy composition that can be 3-D printed by a material extrusion additive manufacturing process, to an acrylic filament that has a very uniform diameter useful in the extrusion additive manufacturing process, to acrylic articles made from the acrylic alloy composition by a material extrusion additive process, and to a material extrusion additive manufacturing process for producing the acrylic articles. The acrylic alloy composition is an alloy of an acrylic polymer, and a low melt viscosity polymer, such as polylactic acid. The alloy may optionally be impact modified, preferably with hard core core-shell impact modifiers.

Abstract:

Embodiments described herein are directed to polymerization-induced phase-separating (PIPS) compositions for enhancement of impact resistance and rheological properties in photocurable resins for 3D printing, such as for inks, coatings and adhesives. Embodiments described herein are advantageous with respect to properties such as impact resistance, shear adhesion and cohesive strength. The PIPS compositions may include components X, Y and Z, wherein X includes an acrylic based monomer; Y includes a copolymer of block A and block B; and Z includes a multifunctional cross-linker. Methods of using the PIPS compositions are also described. Also described are methods of screening potential acrylic based monomeric or oligomeric additives that yield improved impact resistance.

Abstract:

For liver modeling from medical scan data, multiple modalities of imaging are used. By using multiple modalities of imaging in combination with generative modeling, a more comprehensive and informed assessment may be performed. The generative modeling may allow feedback of effects of proposed therapy on function of the liver. This feedback is used to update the liver function information based on the imaging. Based on the computerized modeling with information from various imaging modes, an output based on more comprehensive information and patient personalized modeling and feedback may be provided to assist the physician.
