petpal.preproc.standard_uptake_value.suv(input_image_path: str, output_image_path: str | None, weight: float, dose: float, start_time: float, end_time: float) → ants.ANTsImage

Compute standard uptake value (SUV) over a pet image. Calculate the weighted image sum then divide by the dose and multiplying by the weight of the participant.

Parameters:

• input_image_path – Path to input PET image.

• output_image_path – Path to which SUV image is saved.

• weight – Weight of the participant in kg.

• dose – Dose injected during the scan in MBq.

• start_time – Start time for the SUV calculation in seconds.

• end_time – End time for the SUV calculation in seconds.

Returns:

suv_img (ants.ANTsImage) – The standard uptake value calculated on the input image.
