Shimadzu Sonialvision Safire II
Shimadzu · Model Sonialvision Safire II
2880 x 2880 Matrix Original Quality Image Acquisition Only Shimadzu’s direct-conversion FPD is capable of handling 2880 x 2880-matrix ultra-high-definition images. A cutting-edge digital system directly processes and stores these high-precision images at the original capture quality. Also this new digital radiography unit is designed around the highly reliable Windows® operating system, which makes the rapid processing of high-definition images possible using simple operations. The graphical user interface and mouse provide an intuitive operation environment that is easy to learn and easy to use. 17-inch FPD Covers a Large View Field The 17 x 17-inch maximum view field applies the extremely high definition and density resolution of the direct-conversion FPD across an area equivalent to 14 x 17-inch film. The large distortion-free view field means only minimal positioning movements are required. This ensures trouble-free handling of diverse examination regions, including orthopedic procedures and abdominal imaging of the stomach and large intestine. The increasing use of IVR treatment requires a system that can offer both high image quality and low exposure dose. The Sonialvision Safire II with direct-conversion FPD meets this requirement by incorporating an exposure reduction mechanism matched to the high image performance of the FPD. These two technologies work in tandem to achieve an overall balance between high image quality and low exposure. Parallel Processing Improves Throughput The system's use of concurrent processing allows the writing of image data to and reading from a CD-R disc even during fluoroscopy and radiography. If desired, images can also be transferred to a Viewer and printed to film. Each type of processing is made as independent as possible to shorten the wait time required for peripheral, non-examination processing. The result is an improvement in overall throughput, producing a more efficient examination environment. Wide View Field and Long Stroke Cover a Large Examination Area The FPD's wide 17-inch view field combines with the large longitudinal stroke of the Sonialvision system to cover an extensive imaging area. Furthermore, the table's heavy-duty design supports a patient load of up to 318 kg (700 lb) in the horizontal position. This is the best in its class.
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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Fluoro dose-rate / image-brightness fault
HighSymptoms: Fluoro image too dark or bright, dose creep, ABC / ADRC not tracking.
Root cause: Image-intensifier or flat-panel degradation, or the dose-control loop.
No or inconsistent exposure / generator error
HighSymptoms: Exposure inhibited, generator error code, spot images under/over-exposed.
Root cause: HV generator / tank, tube, filament supply, or an interlock.
Table motion / tilt / spot-film device fault
MediumSymptoms: Table will not tilt or move, the spot-film / carriage will not position.
Root cause: Table drive, tilt motor, or the spot-film device drive.
Tube overload / cooling fault
MediumSymptoms: Exposures inhibited after a series, tube-heat alarm.
Root cause: Tube heat limit reached or a heat-exchanger / cooling fault.
Console / image-chain / PACS fault
MediumSymptoms: Console unresponsive, image freeze, images will not archive.
Root cause: Console PC, the image-processing chain, or the network.

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 starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Fluoro too dark/bright or dose creeping
- Image a phantom at a fixed field and distance and compare to baseline.
- Check the image-intensifier / detector performance via service diagnostics.
- Review the dose / ABC trend.
- Escalate an intensifier or detector degradation to the OEM.
- Re-verify dose rate against the room baseline after correction.
Symptom: Generator error / no exposure
- Record the exact generator error code.
- Confirm mains supply is within spec and all room interlocks are satisfied.
- Confirm the tube is not in a thermal lockout.
- Check the HT connections and exposure contactor.
- Escalate a confirmed HV-tank / tube fault; verify output after repair.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
X-ray R/F system software with certain versions of the control board may occasionally fail to display images when switching from Fluoroscopy mode to Radiography mode, which may lead to the possibility of delay or cancellation of the examination.
- RECALL
Due to the inadequate adjusting criteria in installation, the system generator on two Digital Angiography Systems, the irradiated x-ray may exceed the x-ray radiation dose rate in fluoroscopic mode.
- RECALL
The firm has identified a problem with the control software for the celling arm of the X-Ray System . This software issue could cause the ceiling arm of the device to move after the operator has released the movement lever. This could result in possible collision or harm to the patient or system operator.
- RECALL
Normal operation of the device is to power up the device in the morning, register the first patient, and then perform a fluoroscopy. If, however, the user powers up the device in the morning and makes an error by starting a fluoroscopy while the first patient is still being registered, the device application will abnormally terminate and require service intervention before it can be used again. This event will not occur after the first patient procedure.
- RECALL
When selecting serial radiography with a pulse rate of 7.5fps (including selecting a preset or changing the pulse rate using a temporary edit function) it was observed the indicated "irradiation time" on the X-ray Generator Console, as well as the "integral dose" on the external console of fluoroscopy, were reset to 0. There has been one report of this event.
- RECALL
Shimadzu Medical Systems is recalling Shimadzu X-ray TV System SONIALVISION due to possibility of oil leaking from the x-ray tube housing under certain conditions.
- RECALL
Shimadzu Medical Systems is recalling the Shimadzu X-ray High Voltage Generator due to the possibility of oil leaking from the x-ray tube housing under certain conditions.
