Neuroradiologic applications with routine C-arm flat panel detector CT: evaluation of patient dose measurements.
BACKGROUND AND PURPOSE Since the introduction of flat panel detector-equipped C-arms, the use of flat panel detector CT (FPCT) in the neuroradiologic angiography suite has become more frequent. This examination implicates its own specific radiation exposure. We used the CT dose index (CTDI) concept and adapted it to the special FPCT geometry to provide a consistent comparison with multisection ...
متن کاملThree-dimensional imaging and cone beam volume CT in C-arm angiography with flat panel detector.
We evaluated a new 3D angiography system with a flat panel detector (FPD) for its capabilitiy to acquire volume sets during a single rotation scan and to reconstruct high spatial resolution three-dimensional and cross sectional images, namely cone beam volume computed tomography (CBVCT) images. Present status of the technique, advantages and potential applications are discussed.
متن کاملExperimental study of intracranial hematoma detection with flat panel detector C-arm CT.
BACKGROUND AND PURPOSE Intracranial hemorrhage is a commonly acknowledged complication of interventional neuroradiology procedures, and the ability to image hemorrhage at the time of the procedure would be very beneficial. A new C-arm system with 3D functionality extends the capability of C-arm imaging to include soft-tissue applications by facilitating the detection of low-contrast objects. We...
متن کاملTranscranial access using fluoroscopic flat panel detector CT navigation.
FPCT and navigation software on contemporary fluoroscopic units perform imaging of a quality comparable with conventional CT. They can accurately guide percutaneous procedures, providing live instrument visualization and the capability to re-image without patient transfer. FPCT navigation was used in the placement of a ventricular drain in a 62-year-old woman for subarachnoid-related hydrocepha...
متن کاملVolume-of-interest imaging of the inner ear in a human temporal bone specimen using a robot- driven C-arm flat panel detector CT system.
VOI imaging can provide higher image quality at a reduced dose for a subregion. In this study with a robot-driven C-arm FDCT system, the goals were proof of feasibility for inner ear imaging, higher flexibility during data acquisition, and easier processing during reconstruction. First a low-dose OV scan was acquired allowing an orientation and enabling the selection of the VOI. The C-arm was t...
