Ziehm Vario / Ziehm Vario 3D - Innovative Key Technology.

C-arms of the Ziehm Vario family feature innovative virtual mechanics and variably isocentric movement while retaining the same size and functions of a standard C-arm.

Intraoperative 3D imaging is the basis for highly demanding procedures performed specially in operative orthopedics, traumatology, neurosurgery and oral and facial surgery. The combination with Computer Aided Surgery (CAS) systems opens up new horizons and possibilities.
The generated 3D images are DICOM-compatible.

Intelligent Virtual Mechanics – enables straightforward and highly efficient isocentric imaging
Compact Design – provides customary Ziehm mobility despite the additional isocentric functionality
Variable Isocenter – adjustable to different patient positions
Variable Image Intensifier/Object Distance – ensures flexibility during the procedure, a larger image field and careful dose management
Isocentric Cine Loop – for 3D-like image impression and simplified surgery assessment

Logical User Guidance.

Intuitive Workflow - the touch-screen control panel ‘Vario Center’ provides ergonomic access to all significant functions of isocentric and 3D imaging.
3D Anytime – from standard 2D fluoroscopy to isocentric or 3D mode, right at the fingertips of the user
Anatomical Programs – for full functionality, all options of conventional fluoroscopy, i.e. DSA, RSA, MSA, and the complete range of anatomical programs are available

Ziehm Vario - Isocentricity at its Best.

Ziehm Vario is most suitable for procedures where isocentric 2D image sequences for obtaining additional information are useful, yet, 3D visualization can be dispensed with.

Versatility – supports the whole range from isocentric imaging over all functions for conventional fluoroscopy to various subtraction operation modes for vascular representation.
Isocentric Cineloop – for 3D-like image impression and simplified surgery assessment
Easily upgradeable to a full Ziehm Vario 3D
A highly cost-effective and flexible solution for any hospital.

Ziehm Vario 3D - Reliable Intraoperative Control

Ziehm Vario 3D complements the isocentric functionality of the Ziehm Vario with highly efficient intraoperative 3D imaging.

Facilitation of precise position monitoring of existing implants, screws and osteosyntheses materials.
Significantly more accurate repositioning of bone fractures and reconstruction of joint surfaces compared with two-dimensional imaging processes.
Hitherto unknown high-standard operation safety and postoperative control in the operation room can reduce the number of revision operations and radiological check-ups.
3D imaging is provided fully automatically by orbital movement.
Subject to the imaging quality requirements in relation to the body region being imaged, the number of images taken can be adjusted for dose reduction (30 to 140).
A highly efficient decision-support software assists the surgeon in quickly evaluating the clinical findings and in making a decision as to the necessity of immediate intraoperative revision.

Ziehm Vario 3D - Unique 3D Reconstruction.

Superior 3D Algorithm – Within a few seconds Filtered Back Projection (FBP) calculates a 3D volume of approximately (12,8 cm)3 and a resolution of 256×256×256 voxel from an isocentric 2D imaging sequence
Optional ART-Algorithm (Algebraic Reconstruction Theorem) – provides meaningful images under any imaging condition
Crucial Gain of Information – by means of comprehensive display options, like isocentric cineloop, volume rendering, orthogonal sections (sagittal, axial, coronal) and multiplanar reconstruction (MPR).
Intuitive User Interface – provides good volume orientation and quick imaging workflow of the level under examination in the sagittal, axial or coronal plane
Reliable Intraoperative Control – facilitates the accurate recognition of malpositions and allows for an immediate correction, if necessary
Hence, additional interventions can be avoided, which again has a positive effect on the hospital budget.
