CAT3D is a Radiation Therapy Planning System (TPS) developed by Mevis Informatica Medica, from Brazil. This PDF shows some of the capabilities of CAT3D. CAT3D runs under Windows from version XP to 10, but we recommend the use of Windows 7, 8.1 or 10. CAT3D has ANVISA clearance since 2013 and is used in hundreds of radiation therapy facilities.

1. CAT3D
Radiation Therapy Planning System
• Pencil Beam convolution/superposition.
• Collapsed Cones convolution/superposition.
• Multimodal image registration and fusion.
• Import Dicom CT, MRI, PET, DicomRT-Struct.
• Export DicomRT-Plan, Lantis .rtp and .mlc .
• DVH for up to 16 ROIs simultaneously.
• DVH cumulative and differential.
• DVH allows rendering of custom constrains.
• DRR for static and dynamic fields.
• Export DRRs as Dicom files.
• Isodose presentations over axial, coronal,
sagittal and oblique planes.
• Isodose rendering in 3D window.
• Support for wedges: physical, motorized,
EDW and virtual.
• Optional IMRT planning. Export to solid
modulators and Step&Shoot.
• Support for stereotactic localizers.
• CAT3D runs under Windows (better 7 to 10).
• Needs INTEL CPU, I7 or Xeon recommended.

2. CAT3D
Contouring highlights
• Manual drawing using mouse
or tablet pen.
• Autosegmentation for high
contrast borders.
• Paintbrush contouring.
• Slice-to-slice interpolation.
• ROI add, subtract, translation.
• Create contours from isodoses.
• ROI (volume) expansion
isotropic, anisotropic, with gap
to skin.
• Import ROIs from registered
image sets.
• Bifurcated ROIs

3. CAT3D
Planning highlights
• Multiple dose algorithm: Pencil Beam and Collapsed Cones.
• Heterogeneity corrections based on voxel density. Easy to modify
electron density table for each CT.
• Support for beam modifiers like individual blocks and compensating
filters.
• Templates of fields for standard plan configuration.
• Isodose presentation over axial, coronal, sagittal and oblique planes.
• Isodose surface rendering on 3D window.
• Support for physical and virtual wedges. Motorized and fixed wedges.
• Support for Varian EDW and Siemens Virtual Wedge.
• Add dose from up to eight plans or phases. DVH for multiple phase
plans.
• Calculation of Monitor Units (MU) or treatment time (min or seconds).
• Local or network patients data base. Data base can be shared between
several CAT3D workstations.
• Plan export can be configured to Mosaic, Therapist, ARIA, Lantis and
others.
• Work with multiple plans simultaneously in one workstation, in
parallel. Unlimited instances of CAT3D under Windows, only limited by
RAM memory.
