The present invention is directed to an apparatus for supplying power to a rotatable x-ray tube for generation of an x-ray beam for acquisition of CT data. The apparatus includes a slip ring to transfer power from a stationary inverter to a rotatable HV tank. The HV tank conditions the transferred power and creates a voltage potential across the x-ray tube for x-ray generation. The inverter has a single or pair of series resonant circuits connected either directly to the slip ring or indirectly through a transformer to limit frequency content and reduce common-mode component of the voltage and current waveforms carried by the slip ring as well as reduce power losses.

A Lobster Eye X-ray Imaging System based on a unique Lobster Eye (LE) structure, X-ray generator, scintillator-based detector and cooled CCD (or Intensified CCD) for real-time, safe, staring Compton backscatter X-ray detection of objects hidden under ground, in containers, behind walls, bulkheads etc. In contrast to existing scanning pencil beam systems, Lobster Eye X-Ray Imaging System's true focusing X-ray optics simultaneously acquire ballistic Compton backscattering photons (CBPs) from an entire scene irradiated by a wide-open cone beam from one or more X-ray generators. The Lobster Eye X-ray Imaging System collects (focuses) thousands of times more backscattered hard X-rays in the range from 40 to 120 keV (or wavelength λ=0.31 to 0.1 Å) than current backscatter imaging sensors (BISs), giving high sensitivity and signal-to-noise ratio (SNR) and penetration through ground, metal walls etc. The collection efficiency of Lobster Eye X-ray Imaging System is optimized to reduce emitted X-ray power and miniaturize the device. This device is especially advantageous for and satisfies requirements of X-ray-based inspection systems, namely, penetration of the X-rays through ground, metal and other material concealments; safety; and man-portability. The advanced technology disclosed herein is also applicable to medical diagnostics and military applications such as mine detection, security screening and a like.

A shutter-shield system for radiation protection is applied to a an x-ray generator in a shielded station for inspecting products moving through the station on a conveyor. Deployed in a sliding attachment on a collimator housing of the x-ray generator, a shutter plate is made movable by an actuator and is configured with an aperture that, in the absence of power applied to the actuator, is made to align with a fixed aperture of the collimator so as to allow emission of the x-ray beam as required for normal inspection purposes. Whenever an anomaly in the product loading on the conveyer creates a gap that could otherwise cause an increase in environmental radiation levels, powering the actuator moves the shutter plate to an offset location that offsets the apertures to an effectively closed state to initiate a standby condition wherein x-ray radiation is substantially confined to the interior region of the collimator, without having to shut down the x-ray generator itself.
