A system and method enables the creation of medical images using data
related to ghost artifacts. The method thus allows components of an
imaged subject to be segmented based on state changes in the components
that lead to the controlled production of ghost artifacts. This is
achieved in MR by performed a pulse sequence so that multiple sets of MR
data are acquired in which the signals from a target tissue vary across
the data sets while the signals from a background tissue do not vary
across the data sets. A composite data set is generated by populating
selected k-space lines of the composite data set with information from a
first MR data set and populating the remaining k-space lines of the
composite data set with information from a second MR data set. An MR
image is then reconstructed from the composite data set. The MR image
contains ghost artifacts that faithfully reproduce the 2D or 3D anatomic
detail of the target tissues without signal contributions from the
background tissues, allowing for background-suppressed or segmented MR
images of a target tissue without the need for image subtraction.
