With the system, Ziehm Imaging GmbH provides an active medical device connected to the mains power supply. The above listed medical device is a non-contact device. The accessory is a non-contact accessory. It does not require any contact with the patient to perform its intended use. It provides contactless energy in the form of X-rays.
Preface
Ziehm Imaging GmbH authorizes only trained and skilled personnel to operate this medical device. The system is intended for use by health care professionals such as physicians, orthopedic surgeons, vascular surgeons, neurovascular surgeons, cardiologists, radiologists and technologists in hospitals, outpatient clinics and other clinical environments. Ziehm Imaging GmbH anticipates the system will be used on a nearly daily basis. Ziehm Imaging GmbH applications specialists and/or qualified site personnel provide on-site operator training in the proper use of the system. The medical equipment is intended for fluoroscopies in the field of surgery, e.g. in traumatology, orthopedics, neurology, urology, cardiology. Its motorized movements enable the surgeon to exactly position the system. Its automatic or manual isocentric image acquisition technique enables fluoroscopies of any kind as well as 3D imaging (as an option) in the field of interventional surgery. It assists the surgeon in intraoperative assessment of the anatomical situation or outcome of the surgical procedure by means of optional 3D images and user-definable slice views (axial, sagittal, coronal).
Normal use
The NaviPort option is an interface enabling the connection of third-party navigation systems approved by Ziehm Imaging GmbH to the Ziehm Vision Vario 3D and Ziehm Vision FD Vario 3D. Third-party devices and components used in combination with this system must comply with the safety requirements according to IEC 60601-1 and/or IEC 60601-1-1 or furnish proof of an equivalent degree of safety. To ensure CE conformity, these components must have a CE approval in accordance with Council Directive 93/42/EEC. In addition, a declaration in compliance with Article 12 of the said directive must be provided. For components without CE approval, a conformity assessment procedure is obligatory. Proper and safe operation of the system requires adequate transportation, storage, assembly and installation as well as appropriate use and maintenance. The limit values indicated in the present document must not be exceeded; this applies also when putting the system into service. The system is suitable for interventional procedures according to IEC 60601-2-43. The exposure of humans to ionizing radiation must always be medically justified. Especially when used on pregnant women, adolescents, children, and pediatric patients, all procedures using ionizing radiation should be used with caution or be avoided altogether. However, the final decision lies with the attending physician or attending surgeon.
Contraindications to the use of X-rays
The system may only be operated by personnel who has undergone radiological training.
Operation
In the USA, Federal law restricts use of this device to trained personnel on the order of a physician.
Operation (USA)

Ziehm Vision Vario and Ziehm Vision Vario 3D
The Ziehm Vision Vario 3D differs from the Ziehm Vision Vario by providing additionally 3D views. These 3D views are generated by means of a filtered back projection (FBP) algorithm. The system uses the images of a scan captured with relation to a predefined scan center to compute the three-dimensional representation of an object. The 3D views are always displayed on the reference screen of the monitor cart.
Differences between Ziehm Vision Vario and Ziehm Vision Vario 3D
The fully-digital Ziehm Vision FD Vario and Ziehm Vision FD Vario 3D are designed for demanding, high-precision vascular applications, e.g. in the field of neurology. As these systems are distortion-free, they are especially suitable for afterloading treatment planning and navigation.

Features
Variable scan center
The freely selectable position of the scan center enables the surgeon to define the scan center in certain areas without having to move the patient.
3D reconstruction
It is possible to display multiplanar reconstructions, orthogonal or freely selectable sections, and different surface reconstructions.
Mobility
With its compact design and combined steering & braking system, the systems offer unrestricted mobility at the operating table, even if space is scarce. The easy adjustability of the C-arm and the excellent counterbalancing of the systems make it possible to access even the most difficult positions.
Anatomical programs
Computer-controlled anatomical programs ensure optimum exposure rate and image quality control as well as high operating comfort. A ‘Soft’ program for soft tissue visualization during object localization and a ‘Metal’ program for suppressing image flare resulting from the use of metal implants and surgical instruments complete the automatic functions.
Radiation dose reduction
The superior penetration capabilities of the digital high-frequency generator enable a significant reduction in the patient skin dose. Radiation-free collimation is provided by the system’s ‘Virtual Collimator’.
Image quality
18" flat-screen monitors guarantee flicker-free images. The advanced Full Frame Technology, which uses non-interlacing throughout the entire image processing chain, generates noise-free images without motion artifacts, even if the subject has moved.
Ziehm Vision FD Vario
The Ziehm Vision FD Vario features a fully-digital image processing chain. The digital flat-panel detector ensures distortion-free images.
Image adjustment
Comprehensive real-time image processing functions (customizable noise and area filtering, electronic contrast and brightness adjustment, zooming, radiation-free horizontal and vertical image reversal, digital image rotation) ensure perfect adaptation of the image quality and orientation on the screen to the surgeon’s needs. Further image processing functions are available for saved images (post-processing).
Advanced Active Cooling
2-2
The Advanced Active Cooling system allows for nearly unlimited fluoroscopy times, being often indispensable e.g. in cardiac and vascular surgery or endoscopic applications.
