Abstract: A patient transport system for transporting a patient from a magnetic resonance imaging system to a second imaging system includes an elongated member and first and second coupling mechanisms. The elongated member has an upper surface configured to support a patient. The first coupling mechanism is coupled to the elongated member and is configured to removably couple the elongated member to the magnetic resonance imaging system. The second coupling mechanism is coupled to the elongated member and is configured to removably couple the elongated member to a second imaging system.

Abstract: An x-ray detector includes a first array of radiation detecting cells for detecting a planar radiation beam transmitted through an object undergoing examination, and a second array of detector cells for detecting radiation transmitted past the object without substantial attenuation. A cell in the second array is modified so that the fraction of the incident radiation admitted into the cell for detection is dependent on the position of a beam of x-ray radiation on its radiation-receiving aperture. Analysis of the signal outputs of the modified cell and an unmodified cell yields the position of the x-ray beam on the aperture. Knowledge of the beam position is useful in a method for compensating for the height-dependent detector sensitivity in, for example, a computerized tomography apparatus.
