Abstract: There is disclosed an improved ultrasonic hologram or other ultrasonic imaging process that accurately forms phase and amplitude information of the hologram in a manner that renders the unit relatively insensitive to environment vibrations, and provides long maintenance free functioning lifetime. Specifically, there is disclosed an improved ultrasonic hologram detector component that forms an ultrasonic hologram on the surface of a detection deformable detector material, resulting from the deformation of the surface. The surface deformation is due to the reflection of an ultrasound (ultrasonic) energy profile of the combination of an “object wave” that passes through an object and that of a “reference wave” that is directed to the surface at an off axis angle from the “object wave”.

Abstract: 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.

Abstract: 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.

Abstract: A method and apparatus for generating an acoustic holographic image having a plurality of pulses with different characteristic parameters from each other. More particularly, a sequence contains a plurality of pulses which have different characteristic parameters from each other. An image is created for each sequence and the effect of each pulse in creating the image is varied based on the variation of the characteristic parameter for each pulse. A selectively enhanced acoustic image is thereby obtained.

Abstract: A preferred embodiment of a large diameter solid ultrasonic imaging transducer is illustrated in FIG. 5 with alternate embodiments illustrated in FIGS. 6-9. The large diameter solid ultrasonic imaging lens 100 has a diameter preferably greater than six inches with a focal length-to-diameter ratio of between 1 and 2. The lens 100 has concave surfaces 108 and 110, and is composed of a homogenous material that has an ultrasonic impedance of less than twice that of water and has a density less than the water. Preferably, the velocity of the ultrasonic sound through homogenous plastic material is less than twice that of water. One or both of the concave surfaces 108 and 110 have surfaces that are without a constant radius and curvature, but however are composed of separate radius of curvatures for each small increment of lens surface to properly focus the ultrasound at a desired focal length "L".An alternate embodiment is illustrated in FIG. 6 which has two exterior solid rigid lens elements that are of a concaval-convex nature forming a liquid lens 126 therebetween that has a double convex arrangement for accurately focusing the ultrasound rays to the desired focal length. Preferably, the solid lens surfaces are coated with a one-quarter wave length reflection reduction layer for reducing even further any ultrasonic reflection or energy loss.

Abstract: An acoustically generated image includes only selected acoustical components. When an original acoustic signal interacts with an object, the resultant acoustic signal comprises a diffracted component and an undiffracted component. The acoustical images of the present invention are generated with either the diffracted component only or the undiffracted component only. In an alternative embodiment, the acoustically generated image may comprise selected frequency component(s) from the diffracted component of the acoustic signal.
