Precise Isotropic Scanning From the selections 32 x 0.5 mm or 32 x 1 mm slices a choice can be made depending on the coverage and image detail ness required. If time is critical the 1 mm slices enable the trauma department a 175 cm scan in 17 seconds with a volume reconstruction in just 2 minutes. When details are first priority for all applications isotropic resolution as fine as 0.35mm is available, showing critical details in e.g. advanced cardiac applications. Computed Volume Reconstruction, the way to go Toshiba has taken CT scanning yet another step further. With the newly introduced Volume Viewing you can scan a large volume in a minimum of time where as the Volume Viewing automatically reconstructs the scanned data into the isotropic volume used for diagnosis. No need for axial images anymore. No need to go into the data and reconstruct MPR's. Aquilion 32 uses the full quality of isotropic high resolution and has the details available to you in an instant. Volume Reconstruction also revolutionizes CT archiving. Aquilion 32 does away with the need for thin slice archiving, a problem for many IT-departments. Only the volume used for diagnosis in effect will be stored saving an enormous amount of storage space keeping the total cost of scanning as low as possible. Better results, lower exposure The highly sophisticated Toshiba Quantum denoising (patent pending) enables you to reduce patient dose up to 40%. This gives a completely new dimension to low dose scanning as Quantum denoising gives you the choice of reducing dose without loss of image quality. In addition it is the only dose reduction method offering the possibility to improve image quality at common used low dose settings. Pre-eminently the method to use for paediatric scanning. Easy to upgrade Economy of scale is the decisive factor for many administrators. Frequently faced with restricted budgets, limiting possible future expansions when extra money can be made available. The Aquilion 32 is ready for a fast and cost-effective upgrade path to Aquilion 64. This allows minimized downtime when future demand asks even more from your Aquilion 32 scanner.
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.
Symptoms: Ring or band artefacts, excessive noise, HU non-uniformity, failed daily air/water calibration.
Root cause: Detector-channel drift or a bad detector module, a DAS fault, or air-cal / tube-output drift.
Symptoms: Tube-arc errors, exposure aborts, kV/mA faults, spits, or noisy bearing; tube pulls high heat units.
Root cause: Anode / bearing wear or vacuum degradation - the CT tube is a wear item.
Symptoms: Rotation faults, comms errors during rotation, brush dust, drive alarms.
Root cause: Worn slip-ring brushes, a drive-belt / bearing fault, or the data-transmission link.
Symptoms: Table drifts, will not index to the correct position, height or cradle errors.
Root cause: Table drive, encoder, or brake fault.
Symptoms: Recon hangs or is slow, images will not send to PACS, console errors.
Root cause: Recon-hardware or console-PC fault, or the network / storage.
Symptoms: Over-temperature warnings, exposures inhibited after a series, coolant alarm.
Root cause: Chiller pump / fan, low coolant, or a blocked heat exchanger.
