General information 7

1- 1General informationPreamble 0

To simplify handling and editorial effort for the current CT System Planning Guide (CT Sys-tem PG) a common ...

• CT Basic Planning Guide (CT Basic PG) and

• CT Options Planning Guide (CT Options PG)

were developed.

Therefore, the CT Basic PG and the CT System PG must be used in addition when plan-ning a CT system.

CT Basic PG 0

It includes both common information as well as facts independent of CT model or version that are necessary for planning CT systems.

The basic requirements for planning CT systems may be identical for some systems inde-pendent of the version model.

Therefore, in this CT System PG you find links to the CT Basic PG.

CT Options PG 0

There are CT options available and used by more than one CT system regardless of the CT model or version.

This CT Options PG includes only the required planning information for the CT options that are used by more than one CT system.

The content of this CT Options PG is limited to the technically required information to plan the on-site preparation of the corresponding option only.

Therefore, in this CT System PG you find links to the CT Options PG.



8 General information

Validity 1.1

The contents of this System PG address solely technically required planning information for:

• SOMATOM Definition




Safety information 1.2

NOTE Please observe the additional safety information provided inthe chapter “General information” of the CT Basic PG, printnumber CT00-000.891.02.

CAUTION [ hz_pgdoc_F02G09U02M03 ]

Insufficient spacing between the system and the wall mayresult in injury to the user and patient.

Risk of injury!

Minimum distances between the system and the wall have to be observed in accordance with the planning guide.


The extension of the scan range may result in injury to theuser and the patient.

Risk of injury!



An improperly secured table can cause injury to the user andpatient.

Risk of injury!

Securing the patient table to the floor is mandatory as specified in the planning guide and installation instruc-tions.


Inadequate room shielding can cause risk of injury to usersand surroundings.

Risk of injury!

Adequate room shielding has to be installed.





Tripping (e.g. due to cables) can cause injury to the user andthe patient.

Risk of injury!

The planning guide describes measures to avoid trip-ping.

Floor and building vibrations 0

General

Floor and building vibrations can reduce image quality.

Sources that produce vibrations are, e.g.,

• Railroad routes

• Subways

• Roads

• Road work and construction sites

• Hospital power plants

• Mines, open-cast minings, quarries (explosions)

• Ferry moorings

• Any other sources of striking vibrations

In the 3 spatial directions, the acceleration in vibrations at the mounting points of the com-puted tomography system (Gantry and Patient Handling System PHS) must not exceed the thresholds as described in the following sections.

Continuous vibrations

Fig. 17: Permissible acceleration for continuous vibration - diagram




NOTES:

• The threshold is defined as acceleration rms value (root mean square) in m/s2 of an FFT spectrum derived with a frequency resolution of 1 Hz and using a Hanning window.

• The vibrations have to be measured with a sampling rate of 1000 Hz using an anti-alias-ing filter with a limit frequency of 250 Hz.

• The threshold is valid for vibrations at the installation location with a CT in position.

• Measurements are usually taken at the site before the installation of the CT. Changes in the eigenfrequency of the slab caused by the additional mass of the CT have to be con-sidered when comparing the frequency spectrum with the threshold.

• Values of the threshold are given in (Tab. 10 / p. 45).

Transient vibrations (shocks)

Any transient vibration has to be less than 0.2m/s2 peak-to-peak in the time domain.

• The vibrations have to be measured with a sampling rate of 1000 Hz.

Size of connecting terminal for line voltage cable in the PDC_A / PDC_B cabinets0

Tab. 18 Size of connecting terminals in PDC_A / PDC_B

REPO - Remote Emergency Power Off 0

The UPS must also be switched off via the EPO switch in case of emergency. For this rea-son, the EPO always has to be connected via an on-site cable with the “emergency_stop” contact X20 in the PDC_A.

Emergency operating mode 0

This CT system has two tubes. If one tube fails the CT system can be switched manually via the operating software to a "single-source mode".

The single-source mode lets the customer work with the CT system until the defective tube is replaced by the CSE.

Please note following important information:

1. The single-source mode works only when the PDC_B tube fails.

2. The CT system does not switch automatically to the single-source mode.

3. The operator must manually and consciously switch to the single-source mode.

4. When using the "single-source mode" the CT system cannot use dual-source scan modes. The usable scan modes depend on the software version installed.

5. When using the single-source mode, the CT system runs at a lower level of power con-sumption.

NOTE: A UPS for the entire CT system must always be calculated in the full-load dual-source power consumption value.

6. Independent of the mode used (single- or dual-source), the PDC_A and the PDC_B must always be supplied with power.

NOTE: The CT system can never be operated if only the PDC_A is supplied with power. Not even when it is switched to single-source mode.

NOTE Please note these facts when you are planning the on-sitepower distribution in combination with a UPS for the entireCT system.

The lengths of the cable kits that can be ordered are identical to the free cable lengths for routing between the components. The cable lengths required for internal routing within the components are already added to the lengths of the cable kits that can be ordered. As a result, the final cable lengths delivered consist of both the lengths of the cable kits plus the required length for internal routing. They are therefore always longer than the original length of the cable kit specified.

“Maximum distance, fixed points” means the distance from the floor cut-out to the floor cut-out between the components.

Anti-freeze may be added to the on-site circuit.

Max. mixing ratio up to -25°C: 40%

Adding anti-freeze reduces the cooling output and requires a higher cooling flow rate.

NOTE: Heat up brine to at least + 2°C from an on-site cooling system! Only then can the on-site water flow through the cooling system (inte-grated into gantry)!

Service • Installation of on-site shutoff valves and pressure gauges in the on-site cooling water connection is recommended.

• A measuring system to gather the temperature and the flow rate in the on-site cooling circuit is integrated in the cooling system/gantry. The values can be displayed via software on the monitor for service purposes.

1. After startup, the service, e.g. cleaning, maintenance, and so on, for the filter is the customer's responsibility. SIEMENSdoes not monitor or service the filter.

2. An interface heat exchanger separates 2 existing cooling circuits. The gantry cooling circuit becomes then a closed cool-ing circuit and cannot be polluted by particles from the on-site cooling circuit.
