Section 1 Introduction
1.1 Product Overview
Overview
OverviewOverview
Overview
EUB-5500 is a compact ultrasound scanner with multiple functions equipped with Doppler,
color flow mapping function and so on, which circuits related to image quality are totally
digitalized. It can be connected with phased array probes as well as linear and convex probes,
and applicable to any type of use.
Also, it is fully equipped with various functions such as cine memory, cardiac function
measurement, patient report function and so on. In addition, EUB-5500 runs on WindowsXP
allowing it to be easily connected with various interfaces such as DICOM3.0 and so on.
Features
FeaturesFeatures
Features
(1) True Digital Architecture
All sorts of ultrasound image processing for not only the beam former as a crucial point of
image quality but also all mode of B, M, DOP, CFM and CFA are totally digitalized, and
they are controlled by software.
(2) Improved resolution
Weighting of transmission and reception waves together with digital processing mentioned
above realizes high spatial resolution, wide dynamic range and high contrast resolution.
(3) Improved color frame rate and image quality
Parallel beam and latest image processing technologies realize the Quadra beam process of
color image. It achieves substantial improvement of frame rate compared with
conventional techniques, as well as provides color images with high definition and high
resolution.
(4) Applicable to multiple uses
Not only linear and convex probes but also phased array probes can be connected. Thus it
is applicable to uses from abdomen and obstetrics to circulatory organ.
(5) Non-interlaced monitor as a standard
The RGB non-interlaced monitor adopted allows clear images without flickering to be
viewed.
(6) WindowsXP is adopted as an OS.
WindowsXP is adopted for the operating system (OS). It allows DICOM3.0 and various
interfaces to be easily connected.
(7) Easy-to-use keyboard
Key layout considering frequency of uses improves operability.

3.2.6Action be taken when the hard disk crashes
The followings describe an action to be taken when the hard disk crashes at the customer site.
3.2.6.1 Crash of HDD
Crash of HDD is divided into the following two cases:
1) Hardware crash: Ultrasound scanner does not start up because the HDD cannot be driven
due to degradation of HDD hardware.
2) Software crash: The ultrasound scanner does not start because some file written in HDD
is broken.
These two crashes may not be simply identified. Incase of HDD crash, take the action for
hardware crash.
In either case, the action initializes user setting information. To prevent this initialization,
it is helpful to use “Backup data” of “Main Menu” to backup user setting information
periodically. By restoring this backup to the equipment after taking the action, user setting
information can be protected (Refer to 3.2.3 and 3.2.4 for details).
The action to be taken in the two cases mentioned above will be described in the following
subsections.
3.2.6.2 Preparation before the action
Prepare the following media supplemented to EUB-5500.
1) EUB-5500 System CD (CD-R)
Needs to start Recovery Medium and includes HDD recovery tools. Also, directly it can
run the ultrasound scanner in place of HDD. Hereafter described as CD-R.
2) EUB-5500 Authentic Disk (FD)
Required when the system is provided with any onerous option.
Required for releasing protection of onerous optional functions.
Hereafter described as A-Disk.
A set of these media is supplemented to a system and exclusive to it. If these media
supplemented to the system for which an action is to be taken cannot be prepared, stop HDD
recovery.
NOTE: If using any media of the other system, the unauthorized copy protection function
makes the media unusable after that.
