preview




  1. Note that the preview parameter has a nested-cumulative behaviour, i. e. if one specifies VoCentering's preview parameter together with NxtomoLoader's preview parameter, then VoCentering will effectively be selecting a subset from NxtomoLoader's own subset (rather than the entire dataset). Note also that VoCentering's subset must always be specified by indexing NxtomoLoader's own subset (rather than the entire dataset). For instance, one must set VoCentering's preview parameter to [:, 0, :] in order to select the first slice of any dataset previously loaded by NxtomoLoader, which may, for example, be the [:, 123:456, :] subset of the entire dataset.
  2. If you use any kind of parameter tuning before applying VoCentering, then the latter will receive a dataset of order higher than 3, in which case you must slice the incoming dataset by specifying the preview parameter of VoCentering to be your a desired rank-3 sub-set of that higher-rank dataset. For instance, if you generate a dataset of shape (D, img_W, img_L, T) from (D, img_W, img_L) by applying a single parameter-tuning operation, then you need to slice this new dataset in the last dimension (axis=3), e. g. [:, mid, :, 0] selects the middle slice of (D, img_W, img_L) that corresponds to the first value of the tuning parameter of that operation.

start_pixel




An initial estimate for the pixel coordinate of an optimal CoR.

search_area




If the value of the search_area parameter is set to the default interval of (-50, 50), then VoCentering will attempt to search for an optimal value of CoR in the (start_pixel - 50, start_pixel + 50) interval. For some datasets, this default range of search (100 pixel) may be not sufficiently large to include an optimal value of CoR, leading to subsequent sub-optimal reconstruction. Therefore, if the value of CoR determined by VoCentering is found to coincide with one of the search-interval limits (i. e. either start_pixel - 50 or start_pixel + 50), then this value of CoR may not necessarily be optimal, and one should re-run VoCentering with a larger value of the search_area parameter to confirm this result.
