CAT3D

Radiotherapy treatment planning system with features for 3D, IMRT and 2D treatments. Implements two algorithms for calculating dose distributions: Pencil Beam and Collapsed Cones Superposition. Supports brachytherapy planning and many imaging capabilities including segmentation, 2D and 3D reconstructions, multimodal recording and merging, and orthogonal X-ray localization.

Wide connectivity with patient management systems and treatments, via DicomRT and LANTIS. Support importing DICOM, JPEG and TIFF and import structures in DicomRT-Struct standard.

O.S. and Hardware

CAT3D is a radiotherapy treatment planning system, which has dosimetry capabilities for teletherapy, dosimetry for brachytherapy and an optional module for IMRT.
CAT3D shows isodose curves overlapped with the patient's anatomy for both computer tomography (CT) and magnetic resonance (MRI).

The image processing module allows the generation of sagittal, coronal or arbitrary space-orientated reconstruction and the dosimetry module generates the dose distribution related to any of these reconstructed plans.

For the generation of conformal beams, CAT3D generates digitally reconstructed radiographies (DRR) in beam eye view – BEV.

CAT3D's DRR can be generated by simulating diagnosis X-rays (similar to the simulator's in energy) or high energy X-rays (2 MeV) to obtain images like the simulator films' in the LINAC itself.
The CAT3D PortalCheck tool allows you to overlay the DRR with patient positioning images.
The 3D representantions in perspective are also among the product's resources and allow to fuse in space: anatomy, isodose surfaces and regions of interest defined by the user (ROI).

The dose/volume histograms allow a detailed study of how a region defined as a ROI is being achieved.

We have as a rule to submit the CAT3D to the test cases and standards published by the International Atomic Energy Agency (IAEA). We chose the IAEA standards as our benchmark for representing the consensus opinion of a broad group of medical physics experts representing various continents, including Latin America. In particular, we work with the criteria set out in the documents IAEA TEC DOC 1540 and IAEA TEC DOC 1583.
Several authors have investigated the accuracy of CAT3D under experimental conditions or in published test cases. Among the most significant works, due to their origin and publication, we highlight "Dosimetric verification of radiotherapy treatment planning systems: Results of IAEA pilot study." [1]. In this work the responses of several internationally known planning systems in cases of variable complexity, including heterogeneities, doses in blocked regions, tangential incidences, etc., are studied. The results presented by the tables in this publication place the CAT3D among the most accurate systems available in the market.
