摘要： An imaging system and method provides for the automatic leveling of a hologram detector system. A detector system must be precisely oriented in a proper predetermined orientation. The present invention senses the orientation of a plate to which the detector system is mounted and adjusts driver motors to maintain the detector system at a desired predetermined orientation. In an exemplary embodiment, orientation sensors form a feedback loop to a servo controller to control the position of the motors and thus maintain the detector system at the predetermined orientation. In another aspect of the invention, the patient table may be repositioned with respect to the imaging system. The patient is positioned on a table and imaging performed. If an object of interest is detected, the patient table may be independently repositioned in three orthogonal directions such that the object of interest coincides with an axis of rotation of the patient table. In this manner, the object of interest stays within a predetermined focal plane as the patient is rotated such that the object may be viewed from various angles.

摘要： An acoustical holographic imaging method and apparatus for introducing a reference wave into a hologram surface such that the reference wave does not interfere with an object placed adjacent to or in close proximity to the hologram surface. More particularly, the ultrasonic holographic imaging system may use a reference wave introduced on the side of a thin (3 element) detector that acts as a wave guide; to introduce the reference wave to a liquid-to-gas interface or alternatively, from the topside of the detecting surface through a liquid-to-liquid interface. The system eliminates the acoustic lens system, thereby reducing the size and cost of the system. Further, an object may be placed at the detecting surface, increasing the depth of field of the resultant image and reducing the energy needed from the object source. The system may additionally utilize multiple reference sources.

摘要： An acoustic hologram imaging system constructed from a machined housing having folded optics. Various surfaces of the housing are machined to provide a precise alignment to the optical members to be connected thereto, such as a mirror, a lens assembly, a light emitting laser diode, a camera, and the like. A three-part lens is described having different materials with different indexes of refraction in order to provide a desired focus of the light. In addition, an optical spatial filter is disclosed in which, according to various embodiments, all, some, or none of the light passing therethrough is attenuated for recording of the optical image of the hologram.

摘要： The description details a preferred embodiment of an improved large area ultrasonic transducer 70 capable of reducing the generation of adverse "edge effect" waves. The transducer has a thin piezoelectric wafer 72 that has a high area-to-thickness ratio of preferably between 30 and 300. A front electrode coating 84 is deposited on the front surface 74, over the front edge 77, along the side surface 82 and over the back edge 78 and onto a border of the back surface 76 to minimize the application of a voltage potential along the side surface.A voltage modifying layer 92 is placed on the back surface 76 along the back edge 78 for further minimizing the generation of "edge effect" waves. The layer 92 varies in thickness to progressively decrease the voltage applied to the back surface 76 from a large central area 79(a) to the back edge 78. The layer 92 is preferably composed of a non-piezoelectric dielectric material.
