Different data preprocessing in baselines and 3DSAM-adapter

[csp2002]

I find that when creating the dataloader for baseline models, the value range of the input is 0 to 1 using the following code:
transforms = [
ScaleIntensityRanged(
keys=["image"],
a_min=self.intensity_range[0],
a_max=self.intensity_range[1],
b_min=0,
b_max=1,
clip=True,
),
]

But in 3DSAM-adapter, the value range is the same as the intensity range using the following code:
transforms = [
ScaleIntensityRanged(
keys=["image"],
a_min=self.intensity_range[0],
a_max=self.intensity_range[1],
b_min=self.intensity_range[0],
b_max=self.intensity_range[1],
clip=True,
),
].

Could you please explain more about this difference? Thanks!
