Sagittal view of the MR brain image used in image segmentation examples. To read: >> img = imread(‘brain.png’);

Color image of green fluorescent cells. Image courtesy of Dr. Abu Al-Khabar. They can be used in image segmentation and correction of the nonuniform background. It is used in Application 1. To read: >> img = imread(‘gfp.png’);

Color image of retina captured by a fundus camera. These images can be used to test various image processing algorithms. To read: >> img = imread(‘leftretina.tif);

Gray-level image of an embryo. To read: >> img = imread(‘embryo.tif);

Color image of islet cells To read: >> img = imread(‘isletcells.png);

CT slice from a whole-body image at the abdomen level saved in DICOM format. To read: >> img = imread(‘CTabdomen.dcm);

CT slice from the image of the NEMA image quality phantom in Dicom format. It shows a cross section through the middle of small hollow spheres inside the phantom. To read: >> img = dicomread(‘CTnemaiq.dcm);

X-ray image of a left knee To read: >> img = imread(‘knee.tif);

Flood-field uniformity captured by a gamma camera system and saved in DICOM format. A similar image was used in Chapter 2 to demonstrate the pixel binning operations. To read: >> img = dicomread(‘gcuniformity.dcm);

These are planar images of a dual line source with and without a scattering medium. They were acquired by a gamma camera to test its extrinsic resolution. We have used similar images in Application 2. To read the images: >> img = dicomread(‘duallinesource_ woscatter.dcm); >> img = dicomread(‘duallinesource_ wscatter.dcm);

The reconstructed SPECT images of a triple-point and triple-line source phantoms acquired by a gamma camera system. The former is used to measure the resolution of a SPECT system on air while the latter is used to calculate the resolution with scatter. To read the images: >> img = dicomread(‘SPECTresolution_ onair.dcm); >> img = dicomread(‘SPECTresolution_ wscatter.dcm);

Image of kidney glomeruli captured by an electron microscope and scanned from a hardcopy. Image courtesy of Dr. Abdulgani Thabakhi. To read the image: >> dh = imread(‘glomeruli.tif);
