A combination of sophisticated diagnostic imaging devices such as a CT Scan, a 4D CT scan, a PET scan and MRI imaging, will be utilized to customize your treatment. The use of diagnostic imaging devices in conjunction with the treatment planning CT scan makes it possible to achieve greater accuracy in defining the region to be treated.

CT Simulation with the Phillips Wide Bore CT Scan

CT Simulation is done with sophisticated computers using mathematical models based on the digital imaging scans of the patient. With these models and visualization software, the patient anatomy and radiation beams are emulated.

4D CT Scan

A 4D CT scan, in which the fourth dimension is time, accounts for motion due to breathing. The use of the 4D CT allows WMCC to treat lung tumors to higher doses with greater certainty of tumor location with time.

Positron Emission Tomography (PET) scan creates colored pictures of chemical changes (metabolic activity) in tissues. Because cancerous tumors are usually more active than normal tissue, they sometimes appear as “hot spots” on the PET scan. CT uses special x-ray equipment to obtain cross-sectional pictures of areas inside the body. A computer then assembles these pictures into detailed images of organs, bones and other tissues. A PET/CT scan is a new technology that joins the two imaging tests into a single procedure that provides a more complete picture of the location and growth of cancerous tumors than either test alone.


Magnetic Resonance Imaging (MRI) scanning requires an imaging machine that uses a large magnet, a sophisticated computer and high frequency radio waves to image the hydrogen in the body. The information is gathered and organized by the computer into detailed pictures of specific body parts. MRI produces better soft-tissue images than x-rays and may be requested by your physician.

Image Fusion

Some tumors are visualized better with different modalities such as PET or MRI. With image fusion technology the PET or MRI data is overlaid and registered (aligned) with the treatment planning CT to delineate the tumor.
