Abstract
Methods and apparatus for high speed image acquisition rates in medical imaging are provided. An embodiment includes scanning an R-theta sector slice, wherein R denotes radius of the sector and theta denotes angle of the sector; varying a value of each of phi and theta, such that phi denotes an elevation location of the R-theta slice, and theta is a function of phi; and, iterating the scanning, acquiring by this method at least one image at an improved acquisition rate compared to that of scanning methods using a constant value of theta.
Claims15
A method of scanning at an improved acquisition rate a volume of interest in a subject, the method comprising:
- scanning an R-theta sector slice, wherein R denotes radius of the sector, theta denotes angle of the sector and is a function of phi, and phi denotes an elevation location of the R-theta slice, wherein the scanning is performed at first values of phi and theta;
- varying phi and theta to at least second values of phi and theta, wherein iterating the scanning at the varied values acquires at least one image at an improved acquisition rate compared to that of scanning methods using a constant value of theta.
A medical imaging device for scanning a volume of interest in a subject, the device designed to scan an R-theta sector slice, wherein R denotes radius of the sector, theta is a function of phi and denotes angle of the sector, and phi denotes an elevation location of the R-theta slice;
- and further designed to vary phi and theta over a plurality of values of phi and theta and iterate the scanning at the plurality of resulting varied values of phi and theta, wherein the device acquires at least one image at an improved acquisition rate compared to that of scanning methods using a constant value of theta.
