Velocity measurement of MR-Imaged fluid flows
First Claim
1. A computer-implemented method for measuring velocity of MR-imaged fluid flows, said method comprising use of at least one programmed computer to:
- generate data representing a measure of distance traveled by flowing fluid appearing in at least two MR images of a subject'"'"'s tissue taken at different respective imaging times;
generate data representing at least one fluid velocity measurement of said flowing fluid by calculating at least one instance of distance traveled by said fluid divided by elapsed time during said travel based on said different respective imaging times; and
output said data representing at least one fluid velocity measurement to at least one of;
(a) a display screen, (b) a non-transitory data storage medium, and (c) a remotely located site.

Abstract
Velocity of MR-imaged fluid flows is measured. Data representing a measure of distance traveled by flowing fluid appearing in at least two MR images of a subject'"'"'s tissue taken at different respective imaging times is generated. Data representing at least one fluid velocity measurement of the flowing fluid is generated by calculating at least one instance of distance traveled by the fluid divided by elapsed time during travel based on different respective imaging times. Data representing at least one fluid velocity measurement is then output to at least one of: (a) a display screen, (b) a non-transitory data storage medium, and (c) a remotely located site.
