Data Driven Image Analyses#

Data driven image analyses, including PCA analysis and input function extraction.

Functions#

`temporal_pca_analysis_of_image_over_mask`(...)	Perform temporal PCA (Principal Component Analysis) on a 4D PET image using a specified mask.
`extract_temporal_pca_components_of_image_over_mask`(...)	Extract principal components from temporal PCA on a 4D PET image using a specified mask.
`extract_temporal_pca_projection_of_image_over_mask`(...)	Compute and extract the temporal PCA projections for a masked region in a 4D PET image.
`extract_temporal_pca_quantile_thresholded_tacs_of_image_using_mask`(...)	Extract quantile-thresholded time-activity curve (TAC) values for temporal PCA components from a 4D PET image.
`generate_temporal_pca_quantile_threshold_tacs_of_image_over_mask`(...)	Extract and compute time-activity curves (TACs) for an image using components of PCA projections
`_generate_quantiled_multi_tacs_header`(...)	Generate the header for outputting multiple TACs generated by the quantile threshold function.
`_gen_reshaped_quantiled_tacs`(→ numpy.ndarray)	Generate the aggregated multiple-tacs array for quantile threshold obtained tacs.
