CXR16
16-Slice MDCT System
CXR16 is a multi-slice CT scanner that combines power with ease-of-use and patient-friendly design. The x-ray generator delivers optimal power for superb image quality, while the operator's console establishes an efficient environment for acquisition, reconstruction and post-processing. CXR16 follows in Hitachi's tradition of high product reliability for excellent long-term value.
Scan Features and Parameters --------------------------------------------------------------------------------
Providing enhanced temporal resolution, the CXR16 offers a fast 0.5-second, 360-degree scan time. This enables shorter breath-holds and reduces patient motion artifacts for maximum image quality. Sub-millimeter slices allow for fine detail images and optimize small lesion and small vessel assessment.
CXR16s software facilitates user selection of acquisition and reconstruction slice thickness, allowing for appropriate review of images and volume data sets for diagnosis.
