NewTom VG Pre-installation information Revision 1.0

Rev. 1.0

Data 14 Sept 07

Note 1° Release

Approved by: Marco Serafini, Project Manager

Introduction The NewTom VG is composed of three main parts: the CBCT scanner unit, a control box containing most electronic circuitry and the main workstation (computer with monitor and necessary peripherals).

Cables The NewTom VG includes connecting cables between workstation and scanner unit and between workstation and control box. Two cables connect the control box with the workstation and one cable links the scanner unit directly to the workstation.

(workstation

control box)

(1) the CANbus cable used for the I/O between Workstation and control box; (2) the cable of the external emergency button (the red one placed on the user table) to be used for emergency shut-down.

(workstation

scanner unit)

(1) the Ethernet cable (cat. 5E) for transmission of the acquired images between scanner unit and PC Workstation. Cables are provided by the manufacturer. The standard set of cables is 10m. Optionally, 20m can be requested when ordering the system. In any case the workstation must be located outside the patient's area (keeping a distance of at least 1.5m away from the patient) for electrical safety regulations compliance.

Cables BUNDLE

An approved mains power cord, 10m long, is supplied already connected to the control box. On the mains connection side the cable is un-terminated but prepared for permanent connection into a terminal block with a dedicated circuit breaker before it. It’s the responsibility of the installer, in coordination with the customer, to make available a proper dedicated mains terminal block and arrange the permanent wiring to the terminal block and dedicated circuit breaker (preferably GFCI type, see table 1 for ratings) before it. The connection to the electric system (mains) should not be performed by mean of plug and wall socket.

A bundle of signal cables exits the control box and connects it to the scanner unit. The standard length of this fixed connection is 2.5m. The cables connecting the equipment and workstation have connectors at both extremities; for this reason, make sure that the proper routing path for the cables is available. To pass through a wall (directly from one room to the next room, if necessary) a 5x5cm (2”x2”) hole is adequate.

The control box may be placed behind the scanner if this is not wall fixed, or at each side of the scanner within a 2m distance. See the following typical installation example as reference.

Installation requirements Safety The system must be installed in a room suitable for medical purposes. NewTom VG is a radiological device and must be used according to safety regulations stipulated by the applicable local laws and regulations. Always carefully adhere to applicable regulations about radiation protection, and follow the directions of an accredited Radiation Protection Specialist. Only he can determine whether and what additional radiation shielding barriers may be required for each specific case. To help that determination, a chart is provided hereunder, that reports typical measurement of scattered radiation dose (in µGy/mAs) with a (simulated) patient head. Note that one exam to a real patient typically uses less than 20 mAs.

Room Installation room minimum dimensions: 2m x 3.5m typical (2m x 2.5m minimum) and 2.4m minimum in height. The measure of doors or narrow passages for moving in the equipment parts at installation must be at least 70cm. The device must be installed on a flat horizontal floor.

The unit can be free-standing on its legs. Wall fixation, via the provided brackets, with 2 anchor bolts (or equivalent) 40cm (16 inches) apart and approximately 2m (80 inches) from the floor, is highly recommended. The maximum load that each fixation must be capable to withstand is not critical when the legs are present, since in that case bolt only has the purpose to stabilize but does not bear the load.

Connection to the mains The equipment should be permanently connected to the mains according to the instructions stated in the Service Manual (permanently connected power cord). The equipment is manufactured to work with one of the following input power supply: 100 / 115 / 200 / 215 / 230 / 240 Vac. The factory default setting is 230Vac. Before switching the machine on It’s necessary to check the voltage provided by the mains, if the voltage is different from 230Vac the connection should be changed properly by the installer.

Absorbed power

200 V ∼ (± 10%) / 215 V ∼ (± 10%) / 230 V ∼ (± 10%) / 240 V ∼ (± 10%) 50/60 Hz (± 1%) 5 A max (during x-ray emission) 100 V ∼ (± 10%) / 115 V ∼ (± 10%) 50/60 Hz (± 1%) 10 A max (during x-ray emission)

Shipping The equipment is shipped in three crates: one for the upper part of the mechanical structure, one for the control box, the lower part of scanner unit and its accessories and one for the rotating part of scanner unit. Make sure that enough space is available to uncrate the equipment, and have easy access to the installation site.

The purpose of this document is solely to provide quick references about the installation of NewTom VG. It does not replace the manufacturer manuals: refer to official User and Service Manuals for the details and complete installation requirements and description.
