20130343512 | ADAPTIVE CONTROL OF SAMPLING FREQUENCY FOR COMPUTED TOMOGRAPHY - A method of contrast-enhanced computed tomography (CT) imaging can include repeatedly scanning a target region at a frequency during a session, the frequency initially being a first rate. After detecting an increase of the attenuation of radiation by a contrast-enhanced first structure within a target region, the frequency can be increased to a second rate. After detecting a subsequent decrease in the attenuation, the frequency can be decreased to a third rate. | 12-26-2013 |
20130343513 | GRATED COLLIMATION SYSTEM FOR COMPUTED TOMOGRAPHY - A collimator for a computed tomography imaging device can include first and second leaves positioned on opposing sides of a primary radiation delivery window. The first and second leaves can include first and second gratings having a plurality of attenuating members with a plurality of secondary radiation delivery windows extending between adjacent attenuating members. | 12-26-2013 |
20130343514 | DYNAMIC POWER CONTROL OF COMPUTED TOMOGRAPHY RADIATION SOURCE - A method of contrast-enhanced computed tomography (CT) imaging can include repeatedly scanning a target region an applied power during a session. The applied power can be a first power for a first scan. After the first scan, the applied power for each of a plurality of scans can be selected based on an algorithm. The algorithm can be based on, for example, the attenuation indicated from a preceding scan in the session. | 12-26-2013 |
20130343518 | DYNAMIC COLLIMATION FOR COMPUTED TOMOGRAPHY - A collimator for a computed tomography imaging device can include first and second leaves positioned on and bounding opposing sides of a radiation delivery window. The first and second leaves can be movable to adjust at least one of a size or a location of the primary radiation delivery window relative a the radiation source in a direction non-parallel to an axis of rotation of the radiation source. | 12-26-2013 |
