.. py:function:: 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.

   :param input_image_path: Path to input PET image.
   :param output_image_path: Path to which SUV image is saved.
   :param weight: Weight of the participant in kg.
   :param dose: Dose injected during the scan in MBq.
   :param start_time: Start time for the SUV calculation in seconds.
   :param end_time: End time for the SUV calculation in seconds.

   :returns: *suv_img (ants.ANTsImage)* -- The standard uptake value calculated on the input image.
