20090310836 | Automatic Learning of Image Features to Predict Disease - A method for training a computer system for automatic detection of regions of interest includes receiving patient records. For each of the received patient records a text field and a medical image are identified from within the patient record and the medical image is automatically segmented to identify a structure of interest. The text field is searched for one or more keywords indicative of a particular abnormality associated with the structure of interest. The medical image is added to a grouping representing the particular abnormality when the text field indicates that the patient has the particular abnormality and the medical image is added to a grouping representing the absence of the particular abnormality when the text field does not indicate that the patient has the particular abnormality. The groupings of medical images are used to automatically train a computer system for the subsequent detection of the particular abnormality. | 12-17-2009 |

A plurality of organs, such as heart, liver, kidneys, spleen, bladder, and prostate, are detected in a sense of a bounding box and segmented in the CT volume, detection of each organ bounding box constrained by the detected organ centers and anatomic landmarks. Organ segmentation is via a database-guided segmentation method. | 04-01-2010 |
20100094874 | Method and an apparatus for retrieving additional information regarding a patient record - A method and an apparatus retrieve additional information regarding a patient record. Applying the subject-matter of the present invention clinical experts, such as doctors, can be provided with domain specific background knowledge, and can, hence, be supported in making decisions regarding the treatment of patients. Said additional information can be structured and visualised, which makes the retrieved information understandable also for persons without advanced knowledge regarding data processing. The retrieval of additional information is accomplished by a comparison of data being stored in the patient record and data being stored in a predefined textual resource, such as a ontology, and an identification of further terms describing attributes of the patient record. This finds application in supporting the diagnosis of patients and healthcare related information retrieval tasks. | 04-15-2010 |

A patient-specific dynamic pulmonary trunk data is generated from 4D image data of a patient. The patient is automatically classified as suitable for PPVI intervention or not suitable for PPVI intervention based on the generated patient-specific dynamic pulmonary trunk model. | 09-23-2010 |
20110116698 | Method and System for Segmentation of the Prostate in 3D Magnetic Resonance Images - A method and system for fully automatic segmentation the prostate in multi-spectral 3D magnetic resonance (MR) image data having one or more scalar intensity values per voxel is disclosed. After intensity standardization of multi-spectral 3D MR image data, a prostate boundary is detected in the multi-spectral 3D MR image data using marginal space learning (MSL). The detected prostate boundary is refined using one or more trained boundary detectors. The detected prostate boundary can be split into patches corresponding to anatomical regions of the prostate and the detected prostate boundary can be refined using trained boundary detectors corresponding to the patches. | 05-19-2011 |
