Shimadzu MobileDaRt Evolution Wireless Type
Shimadzu · Model MobileDaRt Evolution Wireless Type
Wireless FPD makes handling easier • The wireless FPD makes it easy to maintain the system asepsis in the operating room or infectious diseases ward. The system offers excellent positioning, with no concerns about cables. Supports display of X-ray exposure dose [Option] • Two kinds of dose management tools are available according to the needs of facilities. A Dose Area Product (DAP) meter can be mounted to the front of the collimator to display dose measurements on the display panel. If a dose calculation function is incorporated in the system, the estimated skin dose is displayed on the main unit display panel prior to taking exposures. Dose data measured with a dose area product meter or calculated skin dose can also be output in DICOM format. • Supports display of X-ray exposure dose [Option] State-of-the-art control software • Two types of digital system are selectable. The optimized workflow reduces steps and supports multiple study acquisition. High power minimizes effect by patient motion • With radiography of children and emergency cases where it is difficult to maintain a stable posture, there is a tendency for images to be blurred due to patient movement. With MobileDaRt Evolution, a maximum output of 32 kw allows for shorter exposure times, eliminating blurring issues. • User firendly design ensures quick positioning and smooth resposive mobility Light-touch, natural maneuvering • A light pressure applied to the drive handle moves the mobile system in a natural manner as if it were an extension of one's hand, allowing the MobileDaRt Evolution to be controlled easily and effortlessly. "Inch-mover" • The MobileDaRt Evolution can be moved forward or backward by using the bedside drive controls located on the front of the collimator. Safety is a major consideration and any sudden force applied to the handle during "Inch-mover" operation stops the MobileDaRt Evolution automatically. In addition, X-ray irradiation is also automatically disabled during any movement of the MobileDaRt Evolution. Keyless Entry(*) • Setting a password for each user enables keyless use of the system. • The Key-less Entry enables to turn on the system by 4 digits key command input without any actual key, which is useful to share the units by several staffs. Wireless Networking (*) • Standard MobileDaRt Evolution features include support of DICOM print and storage. • Output data in DICOM format to a laser printer, image server, or viewer using the provided LAN connection. Optional wireless network connection is available that provides even greater freedom for communication to RIS or PACS while moving the unit.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
X-ray tube overheating / filament failure
HighSymptoms: Tube won't fire, heat-capacity alarm.
Root cause: Filament wear, cooling failure.
Detector calibration drift
MediumSymptoms: Image noise, artifacts, low SNR.
Root cause: Flat-panel / sensor aging.
Cooling system fault
HighSymptoms: Tube temp alarm, duty-cycle limited.
Root cause: Pump/radiator or coolant loss.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or RAID degradation.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: X-ray tube overheating / filament failure
- Confirm the presentation - typically tube won't fire, heat-capacity alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: filament wear, cooling failure.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the x-ray tube insert per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
There is a potential that the adjustable handle option on the X-Ray system may have been installed with improper bolts. This could result in improper driving operation which could lead to harm of individuals around the device.
- RECALL
In these units, the brake is usually released by gripping the drive handle and applied by letting go of the handle. However, for systems within a specified manufacture period, we have identified that even when letting go of the handle, the systems brakes are not applied. In this event, if the Operator releases the handle when the device is moving, the unit will continue to coast.
- RECALL
Cracks may occur over time on the tube holding shaft near the base of the tube mounting flange.
- RECALL
The firm is recalling the Shimadzu Mobile X-ray system because an image may not transfer to image server properly.
