Abstract: A detector array (112) includes at least one detector pixel (306) with a cavity (400) that defines a three dimensional volume. A surface of the cavity includes at least two photosensitive regions and a non-photosensitive region there between, defining at least two sub-pixels (306i, 3062) which detect light photons traversing within the three dimensional cavity and produce respective signals indicative thereof. The detector array further includes a scintillator (302), including a first sub-portion that is located in the cavity and which emits the light photons in response to absorbing x-ray photons. Light photons emitted by the first sub-portion are detected by both of the at least two sub-pixels

Abstract: An ECG electrode is provided which can be placed within the direct path of x-rays during an imaging scan without inducing an x-ray induced erroneous current. The ECG electrode has a support element with a conductive post on one side electrically connected to a conductive plate on the other side. A dissipative anti-static element in or near the ECG electrode dissipates static electricity which forms on the surfaces of the insulating components in the ECG electrode. The dissipative anti-static element may be, for example, a slightly conductive property of the bulk material used to make the insulating material, or a conductive coating added to the insulating material surfaces. The dissipative anti-static element may also be incorporated in the clamp attached to the conductive post. In a further embodiment, an ion blower aimed at the ECG electrode may be used to remove static electricity.
