| 20080240532 | System and Method for Detection of Fetal Anatomies From Ultrasound Images Using a Constrained Probabilistic Boosting Tree - A method for detecting fetal anatomic features in ultrasound images includes providing an ultrasound image of a fetus, specifying an anatomic feature to be detected in a region S determined by parameter vector θ, providing a sequence of probabilistic boosting tree classifiers, each with a pre-specified height and number of nodes. Each classifier computes a posterior probability P(y|S) where yε{−1,+1}, with P(y=+1|S) representing a probability that region S contains the feature, and P(y=−1|S) representing a probability that region S contains background information. The feature is detected by uniformly sampling a parameter space of parameter vector θ using a first classifier with a sampling interval vector used for training said first classifier, and having each subsequent classifier classify positive samples identified by a preceding classifier using a smaller sampling interval vector used for training said preceding classifier. Each classifier forms a union of its positive samples with those of the preceding classifier. | 10-02-2008 |

| 20090010509 | Method and system for detection of deformable structures in medical images - A method and system for detection of deformable structures in medical images is disclosed. Deformable structures can represent blood flow patterns in images such as Doppler echocardiograms. A probabilistic, hierarchical, and discriminant framework is used to detect such deformable structures. This framework integrates evidence from different primitive levels via a progressive detector hierarchy, including a series of discriminant classifiers. A target deformable structure is parameterized by a multi-dimensional parameter, and primitives or partial parameterizations of the parameter are determined. An input image is received, and a series of primitives are sequentially detected using the progressive detector hierarchy, in which each detector or classifier detects a corresponding primitive. The final detector detects configuration candidates for the deformable structure. | 01-08-2009 |

| 20110023970 | DEVICE FOR CREATING A MICROFLUIDIC CHANNEL STRUCTURE IN A CHAMBER - A device for creating a microfluidic channel structure includes two plates forming a chamber between the two plates. The chamber has at least one inlet for feeding a fluid into the chamber and at least one outlet for discharging the fluid out of the chamber. A cooling element is associated with at least one of the two plates for converting fluid disposed in the chamber into a solid. A plurality of heating elements is associated with at least a first of the two plates and distributed so as to provide, by a heating up of some of the heating elements so as to convert areas of the solid that are in a vicinity of the heating elements to the fluid, a channel structure leading from the at least one inlet through the chamber to the at least one outlet. The channel structure is configured to convey fluid flow. | 02-03-2011 |

| 20100062066 | Formulations of Tetrahydropyridine Antiplatelet Agents for Parenteral or Oral Administration - A pharmaceutical composition for the oral or parenteral administration of a compound of Formula (I) comprising an oil in water emulsion, wherein the oil phase comprises the free base of or a pharmaceutically acceptable salt thereof of a compound of Formula (I), and one or more surfactants which are soluble in the oil phase and/or the aqueous phase. The emulsion optionally contains one or more excipients that are soluble in the oil phase and/or the aqueous phase, such as pH modifying agents such as buffers, osmolality/tonicity modifying agents, emulsifying agents, water-soluble polymers, and preservatives. The compound of Formula (I) can be formulated as a solid material and stored until needed. Kits for forming the emulsion are provided. Prior to administration, the solid material can be reconstituted in an aqueous medium to form the emulsion. | 03-11-2010 |
