Abstract
A method and system for reducing radiation exposure from an imaging system including determining an entry location, operating the imaging system so as to cause the imaging system to emit radiation having a radiation intensity, controlling the radiation intensity in a manner responsive to the entry location so as to create image data and processing the image data so as to create processed image data. In an alternative embodiment, a medium encoded with a machine-readable computer program code for reducing radiation exposure from an imaging system, the medium including instructions for causing a controller to implement the aforementioned method.
Claims36
A method for reducing radiation exposure from an imaging system comprising:
- determining an entry location;
- operating the imaging system so as to cause the imaging system to emit radiation having a radiation intensity;
- controlling said radiation intensity in a manner responsive to said entry location so as to create image data;
- and
- processing said image data so as to create processed image data.
A medium encoded with a machine-readable computer program code for reducing radiation exposure from an imaging system, said medium including instructions for causing controller to implement a method comprising:
- determining an entry location;
- operating the imaging system so as to cause the imaging system to emit radiation having a radiation intensity;
- controlling said radiation intensity in a manner responsive to said entry location so as to create image data;
- and
- processing said image data so as to create processed image data.
A method for reducing the physician's radiation exposure from an imaging system while maintaining patient dose and image quality comprising:
- obtaining an object to be scanned;
- operating the imaging system so as to create image data;
- displaying said image data on an output device;
- and
- processing said image data using a processing device, wherein said processing device, determines an entry location;
- operates the imaging system so as to cause the imaging system to emit radiation having a radiation intensity;
- controls said radiation intensity in a manner responsive to said entry location so as to create image data;
- and
- processes said image data so as to create processed image data.
A system for reducing the physician's radiation exposure from an imaging system while maintaining patient dose and image quality comprising:
- a gantry having an x-ray source and a radiation detector array, wherein said gantry defines a patient cavity and wherein said x-ray source and said radiation detector array are rotatingly associated with said gantry so as to be separated by said patient cavity;
- a patient support structure movingly associated with said gantry so as to allow communication with said patient cavity;
- and
- a processing device, wherein said processing device, determines an entry location;
- operates the imaging system so as to cause the imaging system to emit radiation having a radiation intensity;
- controls said radiation intensity in a manner responsive to said entry location so as to create image data;
- and
- processes said image data so as to create processed image data.
A system for reducing the physician's radiation exposure from an imaging system while maintaining patient dose and image quality comprising:
- an imaging system;
- a patient support structure movingly associated with said imaging system so as to allow communication between said imaging system and a patient, wherein said imaging system generates image data responsive to said patient;
- and
- a processing device, wherein said processing device, determines an entry location;
- operates the imaging system so as to cause the imaging system to emit radiation having a radiation intensity;
- controls said radiation intensity in a manner responsive to said entry location so as to create image data;
- and
- processes said image data so as to create processed image data.
