2D Display

Visualization of imaging volumes is essential for controlling the loaded DICOM objects. The espadon package allows this display, with the possibility of using the color palettes of your choice.

The display.kplane function displays a slice plane of the imaging volume in the slice plane geometric frame of reference.

CT <- load.obj.from.dicom(ct_dicom_file_path)
display.kplane (CT, k =10, col = pal.RVV(1000), 
                breaks = seq(-1000, 1000, length.out = 1001),
                ord.flip = TRUE, interpolate = TRUE) 
Slice display of the CT, with the palette developed by Silverstein & al [1].

The display.plane function displays transverse, frontal or sagittal views in the patient’s frame of reference. It allows the superposition of images and contours.

Transverse (a), frontal (b), and sagittal (c) views of the overlay of MR, rt-dose and part of rt-struct RoI (regions of interest), in the frame of reference of rt-dose and rt-struct, displayed using the display.plane function. The display.palette function is used to display palettes.
