| 20080208044 | COMBINED NUCLEAR AND SONOGRAPHIC IMAGING APPARATUS AND METHOD - The present invention relates to an apparatus for use in medical imaging and a medical imaging method. The apparatus comprises nuclear medicine imaging means including detector means for detecting radiation as emitted upon decay of a radiopharmaceutical injected into a living object's body as well as means for generating a nuclear medicine image of said living object based on the detected radiation. The apparatus further comprises ultrasonography imaging means for also generating an ultrasonography image of the same living object. | 08-28-2008 |
| 20090149760 | ULTRASOUND IMAGING PROBE FOR IMAGING A TEMPORARY CHANGE IN AN ENVIRONMENT - The invention relates to an ultrasonic imaging probe for imaging a medium ( | 06-11-2009 |
| 20090268952 | METHOD AND APPARATUS FOR AUTOMATICALLY DEVELOPING A HIGH PERFORMANCE CLASSIFIER FOR PRODUCING MEDICALLY MEANINGFUL DESCRIPTORS IN MEDICAL DIAGNOSIS IMAGING - A method for determining the presence or absence of malignant features in medical images, wherein a plurality of base comparison or training images of various types of lesions taken of actual patient is examined by one or more image reading experts to create a first database array. Low-level features of each of the lesions in the same plurality of base comparisons or training images arc determined using one or more image processing algorithms to obtain a second database array set. The first and second database array set are combined to create a training database array set which is input to a learning system that discovers/learns a classifier that maps from a subset of the low-level features to the expert's evaluation in the first database array set. The classifier is used to determine the presence of a particular mid-level feature in an image of lesion in a patient based solely on the image. | 10-29-2009 |
| 20100222678 | METHOD AND DEVICE FOR MEASURING A MEAN VALUE OF VISCO-ELASTICITY OF A REGION OF INTEREST - The invention relates to a method for measuring a mean visco-elasticity value for a soft material. Said method using a single probe carrying at least one transducer comprises the steps of: | 09-02-2010 |

| 20100168566 | METHOD AND A DEVICE FOR IMAGING A VISCO-ELASTIC MEDIUM - The invention relates to a method and a device for imaging a visco-elastic medium. The method comprises an excitation step during which an internal mechanical stress is generated in excitation zone and an imaging step of acquiring signals during the movements generated by the mechanical stress in the visco-elastic medium in response to the internal mechanical stress in an imaging zone that includes the excitation zone. According to the invention, the method further comprises a step of calculating a quantitative index associated with the rheological properties of the visco-elastic medium at at least one point of the imaging zone situated at a given depth outside the excitation zone. The quantitative index is representative of a comparison between signals acquired during the movements generated in response to the mechanical stress at at least one point of the excitation zone situated at the given depth, and signals acquired during the movements generated in response to the mechanical stress at at least the point of the imaging zone situated outside the excitation zone. | 07-01-2010 |

| 20090118670 | Cannula inserting system - The invention relates to a highly automated puncture system for inserting a cannula or a needle into a blood vessel of a person or an animal. The puncture system has an acquisition module that allows for determining at least a location of a blood vessel underneath of the surface of a skin and is further enabled to determine an optimal puncture location that is potentially suitable for inserting a cannula into the blood vessel. Further, the puncture system has tissue analysis means to analyse the skin surface in the proximity of the puncture location to check whether the skin is suitable for punctuation. This prevents puncturing the skin at locations where scars, wound and the like can be found. | 05-07-2009 |
