MOSAIQ® is an oncology information system used to manage workflows for treatment planning and delivery. It supports information flow among healthcare facility personnel and can be used wherever radiotherapy and/or chemotherapy are prescribed. Users can configure MOSAIQ® for Medical Oncology use, Radiation Oncology use, or the two together. It lets users:

• Assemble electronic patient charts and treatment plans, order diagnostic tests, and prescribe medications.

• Generate and keep medication formulary lists and calculate applicable medication dosages for medical oncology.

• Import, view, annotate, adjust, enhance, manage and archive images.

• Compare radiation treatment plans and evaluate dose coverage.

• Design leaf plans for operation with radiotherapy treatment machines that have multi-leaf collimators.

• Make sure radiation treatment plans imported from treatment planning systems agree with treatment machine constraints. MOSAIQ® reads actual settings from the treatment machine through the machine communication interface. It compares these settings with predefined values. If a mismatch occurs between the planned values and the actual machine settings, the system warns the user.

• View reference images to setup treatment. MOSAIQ® refers to predefined settings to help treatment machine setup and communicates patient and machine setup instructions.

• Record actual delivered radiation values in an electronic chart to track treatment.

• Use stereotactic localization to calculate set-up coordinates for treatments.

• Monitor Intrafractional motion with real time image overlay.

MOSAIQ® is not intended for use in diagnosis.

Indications for use as stated in the FDA summary.
