See & Treat™ Cancer Care is a revolutionary breakthrough in imaging and radiotherapy systems. Industry leaders GE Medical Systems and Varian Medical Systems have combined resources to provide a single, comprehensive suite of integrated imaging, information management and treatment solutions.

See and Treat Cancer Care is more than just equipment. With superior service and information management systems, GE and Varian are raising convenience and accessibility to new heights.









CT is the standard of care for imaging for radiation therapy planning. CT provides excellent anatomical information.

PET/CT adds metabolic information to anatomical structures, allowing better visualization of lesions for more precise treatment planning.

MR/MRS (Magnetic Resonance Spectroscopy) provides excellent soft tissue resolution. MRS shows molecular changes that can signal the presence of cancer.



Multi-modality image registration combines different kinds of images so clinicians can better visualize lesions and critical structures.

The clinician imports DICOM image sets from CT, PET, or MR to the image registration software. The images from each data set are co-registered, enabling the clinician to better localize the target.

Using virtual simulation software, the clinician delineates the target and defines the isocenter.

Conventional simulation can be used to define the isocenter with fluoroscopy before the planning CT. For patients undergoing palliative care, conventional simulation is used for accurate, efficient isocenter definition.


The patient setup is verified by imaging the patient in the treatment position. This may be static or fluoro imaging. Patient positioning, reproducibility of the setup, and isocenter verification are completed at this time. Verification allows for analysis of motion and its effect on the treatment plan before delivering any treatments.

Clinicians can prepare reference images (simulation image or a DRR created during treatment planning) for treatment. In addition, the clinician can view the treatment field parameters and the room's eye view all from the same workspace.

For IMRT pre-treatment QA, the linac creates a portal dose image for comparison to the treatment planning dose map.


The clinician sets up the patient using parameters from the plan, and compares portal images with DRRs that were generated during the planning and verification steps. Reference images are used at the treatment unit to compare daily portal images.

The therapist sets up the patient for treatment by visualizing the field with a DRR and loads parameters from the approved plan.

Dose delivery can be gated to mitigate respiratory motion during treatment.

In the future, clinicians could have the ability to re-position the patient utilizing kV imaging. The image data could then be used for verification and re-planning. This could be a fluoro-based imaging modality to manage and monitor motion in the treatment room.


Multi-modality imaging may again be utilized to check the results by tracking progress of treatment and verifying treatment outcomes.

CT provides excellent anatomical information.

PET/CT combines metabolic activity with anatomical information.

MR/MRS provides excellent soft tissue resolution. MRS shows molecular changes that can signal the presence of cancer.
