20100098214 | Methods and Systems for Treating Breast Cancer Using External Beam Radiation - A radiation apparatus includes a radiation source movable in translational and/or rotational degrees of freedom, and a structure adapted to support a body. The structure is provided with an opening to allow a portion of the body passing through to be exposed to at least a portion of the therapeutic radiation while in use. | 04-22-2010 |
20120027271 | KNOWLEDGE-BASED AUTOMATIC IMAGE SEGMENTATION - A method for medical image segmentation. The method includes accessing and updating a knowledge-base in accordance with embodiments of the present invention. The techniques include: receiving a medical image and computing a sparse landmark signature based on the medical image content. Next, a knowledge-base is searched for representative matches to form a base set, wherein the base set comprises a plurality of reference image sets. A portion of the plurality of reference image sets of the base set is deformed to generate mappings from the base set to the medical image set. Finally a weighted average segmentation for each structure of interest of the medical image set is determined. | 02-02-2012 |
20120027273 | KNOWLEDGE-BASED AUTOMATIC IMAGE SEGMENTATION - A method for medical image segmentation includes accessing and updating a knowledge-base. First, a medical image is received and a sparse landmark signature is computed based on the medical image. Next, either a representative or a cohort average reference image set is selected. A portion of either representative reference image set or the cohort average reference image set is deformed to generate mappings to the medical image set. A segmentation for each structure of interest of the medical image set is determined. The knowledge-base is searched for representative matches to form a plurality of sub-volume base sets comprising a plurality of reference image set sub-volumes. A portion of the plurality of reference image set sub-volumes of the plurality of sub-volume base sets is deformed to generate mappings from the plurality of sub-volume base sets to corresponding structures of interest of the medical image set. A weighted-average segmentation for the plurality of structures of interest in the medical image set is calculated. | 02-02-2012 |
20120197656 | RADIATION THERAPY KNOWLEDGE EXCHANGE - A method for implementing a radiation therapy knowledge exchange starts with searching a database of cases studies and selecting a case study. The selected case study is downloaded. The downloaded case study is applied to a medical case, wherein the downloaded case is applied using deformable image registration to deform reference images of the downloaded case to medical images of the medical case. After application of the downloaded case study, the medical case is uploaded to the network, wherein uploading the medical case allows at least the submitting clinician to download, review, and edit at least a portion of the medical case to create a reviewed medical case. Finally, the reviewed medical case is downloaded and applied to the medical case to create a final medical case. | 08-02-2012 |
20130077752 | RADIATION THERAPY TREATMENT PLAN IMPROVEMENT THROUGH USE OF KNOWLEDGE BASE - A radiation therapy dose distribution method starts with selecting a treatment type. Then an organ at risk (OAR) distance to target map is determined. The OAR distance to target map comprises distances to a target organ for portions of an OAR. The OAR distances are determined from at least one segmented patient organ image. A cohort average dose distance to target histogram is selected. A dose value to the portions of the OAR are assigned to form a first 3D dose distribution map. The dose values are from the selected cohort average dose distance to target histogram. A second 3D dose distribution map is determined based on a field arrangement determined by the treatment type and the first 3D dose distribution map. A dose distance to target histogram is calculated using the second 3D dose distribution map and the distance to target map. | 03-28-2013 |
20130085343 | SEMANTIC RADIATION TREATMENT PLAN OPTIMIZATION GUIDANCE - A method for radiation therapy treatment plan optimization, comprising generating a first radiation therapy treatment plan for a patient using a selected treatment type from a database and optimizing the first radiation therapy treatment plan. A selection of metrics from the first radiation therapy treatment plan are identified and compared to metrics from aggregated prior patient records selected from the database. At least one parameter is identified that affects the ability of the first radiation therapy treatment plan to meet an identified metric. The at least one parameter for the identified metric is compared to at least one parameter for a competing metric and at least one alternative treatment step for the treatment plan is determined that will change the identified at least one parameter to improve the identified metric. | 04-04-2013 |
20140275710 | RADIATION THERAPY TREATMENT PLAN IMPROVEMENT THROUGH USE OF KNOWLEDGE BASE - A method for determining a radiation therapy dose distribution starts with selecting and downloading a treatment type from a database. Then an organ at risk (OAR) distance to target map is determined, wherein the OAR distance to target map comprises distances to a target organ for respective portions of at least one OAR, and wherein the OAR distances are determined from at least one segmented patient organ image. Now a cohort average dose distance to target histogram is selected and downloaded from the database. After which, a dose value to the portions of the at least one OAR are assigned to form a first 3D dose distribution map, wherein the dose values are from the selected cohort average dose distance to target histogram. Now a second 3D dose distribution map is determined based on a field arrangement determined by the treatment type, and the first 3D dose distribution map. Finally, a dose distance to target histogram is calculated for the patient using the second 3D dose distribution map and the distance to target map. | 09-18-2014 |
20150045604 | SYSTEM AND METHOD FOR PATIENT-SPECIFIC MOTION MANAGEMENT - A medical method includes: determining a first probability density function related to a first uncertainty in hitting a target in a treatment of the target; determining a second probability density function related to a second uncertainty, wherein the first uncertainty is attributable to a first source of uncertainty, and the second uncertainty is attributable to a second source of uncertainty that is different from the first source of uncertainty; processing at least the first probability density function and the second probability density function using a processing unit; and outputting a result of the processing. | 02-12-2015 |
