Abstract
Computed tomography devices, systems, and associated methods are disclosed. The device can include a radiation source coupleable to a rotating gantry to emit radiation from an adjustable focal spot toward a volume of interest. The device can also include a dynamic collimator associated with the radiation source and located between the focal spot and the volume of interest. The dynamic collimator can define an aperture that is adjustable to permit radiation to pass through the volume of interest. The focal spot can be adjustable to maximize resolution within the volume of interest.
Claims22
A computed tomography device, comprising:
- a radiation source coupleable to a rotating gantry to emit radiation from an adjustable focal spot toward a volume of interest;
- and
- a dynamic collimator associated with the radiation source and located between the focal spot and the volume of interest,
- wherein the dynamic collimator defines an aperture that is adjustable to permit radiation to pass through the volume of interest, and
- wherein the focal spot is adjustable to maximize resolution within the volume of interest.
A computed tomography system, comprising:
- a rotating gantry configured to rotate about a volume of interest;
- a radiation source coupled to the gantry to emit radiation from an adjustable focal spot toward the volume of interest;
- a dynamic collimator associated with the radiation source and located between the focal spot and the volume of interest;
- and
- a radiation detector positioned opposite the radiation source and dynamic collimator to receive radiation that has passed through the volume of interest,
- wherein the dynamic collimator defines an aperture that is adjustable to permit radiation to pass through the volume of interest, and
- wherein the focal spot is adjustable to maximize resolution within the volume of interest.
A method of radiologic imaging, comprising:
- emitting radiation from a focal spot of a radiation source toward a volume of interest;
- adjusting an aperture of a dynamic collimator located between the focal spot and the volume of interest to permit radiation to pass through the volume of interest;
- and
- adjusting the focal spot to maximize resolution within the volume of interest.
