Detailed Description

Data model for a single 2-D MRI volume slice.

Holds the greyscale slice image, orientation metadata, and the slice-to-world transform. Generates a textured quad and vertex/UV data for upload to a QRhi renderer via the slice.vert / slice.frag shaders.

setSlice()

void SliceObject::setSlice	(	const QImage &	image,

		int	sliceIndex,
		const Eigen::Matrix4d &	voxelToWorld )

Set the slice image data and orientation.

Parameters

[in]	image	Greyscale slice image (QImage::Format_Grayscale8 or 16).
[in]	orientation	Axial, Sagittal, or Coronal.
[in]	sliceIndex	Index along the perpendicular axis (voxel units).

		const Eigen::Matrix4d &	imageToWorld )

Set the slice image data with an explicit image-to-world transform.

Parameters

[in]	image	Greyscale slice image (QImage::Format_Grayscale8 or 16).
[in]	orientation	Anatomical orientation of the slice.
[in]	sliceIndex	Index along the perpendicular voxel axis.
[in]	imageToWorld	4x4 transform from image coordinates (column, row, 0) to RAS.
