Calculates the mean frame across the specified range of frames in the 4-dimensional PET data.

Parameters:

• pet_4d_data (np.ndarray) – 4-dimensional array representing the PET data.

• start_frame (int) – The starting frame index for the mean calculation.

• end_frame (int) – The ending frame index for the mean calculation.

Returns:

mean_frame (np.ndarray) – The mean frame calculated from the specified range of frames.
