Flexitron Afterloader by Isodose Control (Click to visit home page)

HDRplus™ / Flexiplan™ Version 2.6

The user friendly and patient oriented 3D treatment planning system for HDR Brachytherapy.

Distributed worldwide under the name HDRplus™ by Eckert & Ziegler BEBIG GmbH and under the name Flexiplan™ by Isodose Control B.V. Flexiplan™ is FDA 510(k) and Health Canada approved.

The high dose rate brachytherapy treatment planning system has evolved from sonoTECH's advanced seed treatment planning system PSID. With the experience from the development of the most sophisticated seed therapy planning system in mind, sonoTECH has developed a state-of-the-art HDR planning software system equipped with a comprehensive set of features, setting the pace in combining effectiveness with ease of operation.

Smart user interface for quick planning results
Applicator library ensures fast and effective planning
All tools in one program: Film-based planning, 3D image sequence based planning, real time prostate module
Dicom RT functionality for easy integration
Real 3D contouring in all views to quickly match clinical volume
Running under Windows™ XP™, Vista™ and Windows™ 7 in administrator and standard mode

Reconstruction Methods

Various reconstruction methods will match every clinical case. The reconstruction can be based on coordinates, planar X-ray images or using CT, MRI, PET or US images. For film based reconstruction the following options are available:

Orthogonal
Reconstruction box
Isocentric with deviation
Variable angle

Applicator Library

Allows the user to load previously stored standard applicators or applicator groups including control points, etc. For each applicator the material (taken into account during calculation), default active positions, placed dose points and if possible the standard shape can be stored. This will allow fast reconstructions based on your preferences. User defined applicators can easily be added to the library.

Dose Optimization

Several dose optimization methods are available to obtain the optimal dose plan desired. Its inverse planning capabilities allow you to provide an optimal dose to the target whilst sparing healthy tissue.

Dose Optimization Methods

Volume optimization using inverse planning
Geometric optimization
Prescription dose to a point
Manual dose optimization (dose shaper)

Dose Visualization

Isodoses can be displayed in all 2D & 3D views. The color coded surface dose option supports the user to identify under or over dosed areas of the volumes.

Plan Evaluation

The plan is evaluated by means of the dose volume histogram. It displays the cumulative and differential histograms of any contoured structure as well as the natural histogram for the target volume. This function is completely interactive and is updated on every modification made to the plan.

Real-time calculation of cumulative, differential and natural dose volume histogram
3D display of isodose lines
3D display of surface dose on critical organs

Dicom RT connectivity

3D data sets from different imaging modalities can be imported directly via optical media or hospital network. It enables the user to communicate with the patient management systems in the department.

DICOM Import of:

DICOM 3.0 images, DICOM RT Struct

DICOM Export of

DICOM RT Plan, RT Dose, RT Struct, Images

Image Fusion

Co-registration and fusion of two image sequences with up to 768 images is possible with manual matching or automated based on landmarks.

Compatibility

Full compatibility with Windows™ XP™ and Vista™
Multilingual user interface
Context sensitive help function
Conform to TG43 dose calculation, including update 2
Dual and quad core CPU support for faster processing

Image Processing

Oblique planes
Image acquisition from US device via frame grabber
