Checking image registration¶

This viewer and widget are designed to compare two images and check if the registration was correct.

class CheckboardView(render_window_interactor, reader, widget)[source]¶

Viewer to compare two images

change_space(*args, **kwargs)[source]¶

Change current coordinate system

new_space (str) : new coordinate system, see get()

get_number_of_image_slices()[source]¶

Gets the number of slices available in the current direction

Returns:	The number of available slices

reset_camera(*args, **kwargs)[source]¶

resets the current camera to standard locations.

Parameters:	position (int) – 0: initial 3d view 1: left 2: right 3: front 4: back 5: top 6: bottom

set_image_slice(*args, **kwargs)[source]¶

Set plane widget slice

Parameters:	new_slice (int) – Index of desired slice

set_img1(*args, **kwargs)[source]¶

Sets the first image

Parameters:	subj – Subject image code img_class (str) – image class (see `braviz.visualization.subject_viewer.ImageManager.change_image_modality()`) img_name (str) – image name (see `braviz.visualization.subject_viewer.ImageManager.change_image_modality()`) contrast (int) – contrast for fMRI images force (bool) – if `True` force reloading the data

set_img2(*args, **kwargs)[source]¶

Sets the second image

Parameters:	subj – Subject image code img_class (str) – image class (see `braviz.visualization.subject_viewer.ImageManager.change_image_modality()`) img_name (str) – image name (see `braviz.visualization.subject_viewer.ImageManager.change_image_modality()`) contrast (int) – contrast for fMRI images force (bool) – if `True` force reloading the data

set_number_of_divisions(*args, **kwargs)[source]¶

Set number of divisions in the checkboard pattern

Parameters:	divs (int) – Number of divisions

set_orientation(*args, **kwargs)[source]¶

Sets orientation of the plane widget

Parameters:	orientation_int (int) – 0 is x, 1 is y, 2 is z

class QCheckViewer(reader, parent)[source]¶

Wraps the CheckboardView so that in can be connected to Qt applications.

initialize_widget()[source]¶: Call this function after calling show on the widget or a parent

slice_change_handle(new_slice)[source]¶: Emits a qt signal when the current slice is changed from vtk
