    • 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 fluid, 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".
    • 公开了一种改进的超声全息图或其它超声波成像方法,其以使得单元对环境振动相对不敏​​感的方式精确地形成全息图的相位和振幅信息,并且提供长的免维护功能寿命。 具体地,公开了一种改进的超声全息图检测器部件,其在检测流体的表面上形成超声全息图,这是由于表面的变形引起的。 表面变形是由于穿过物体的“物体波”的组合的超声波(超声波)能量曲线的反射和以离轴角度指向表面的“参考波”的超声波 “对象波”。

    • 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.
    • 成像系统和方法提供全息图检测器系统的自动调平。 检测器系统必须以适当的预定取向精确地定向。 本发明感测安装有检测器系统的板的方向,并且调节驱动器电机以将检测器系统保持在期望的预定取向。 在示例性实施例中,定向传感器形成到伺服控制器的反馈回路,以控制电动机的位置,从而将检测器系统维持在预定方位。 在本发明的另一方面,患者台可以相对于成像系统重新定位。 患者被放置在桌子上并进行成像。 如果检测到感兴趣的对象,则可以在三个正交方向上独立地重新定位患者台,使得感兴趣的对象与患者表的旋转轴线重合。 以这种方式,感兴趣的对象在患者旋转时保持在预定焦平面内,使得可以从各种角度观察对象。

    • There is disclosed an apparatus and a process for enhancing images of subtle structures, such as tumor tissue within a soft tissue matrix. Specifically, the process and apparatus provides a transmissive ultrasonic holography imaging system having an acoustical opaque small element (4a) variably placed so as to block that portion of the transmitted sound that is not scattered by the object. Alternately, the process and apparatus provides for an acoustical opaque plane (4a) with an opening variably placed so as to block plane that portion of the transmitted sound that is scattered by the object. Alternately, the process and apparatus provide for an acoustically opaque element in the shape of a plane (2b) with circular openings variably placed so as allow passage only that portion of the transmitted sound that is scattered by the object at a selected location within the focal plane of the lens means.

    • There is disclosed an apparatus and a process for enhancing images of subtle structures, such as tumor tissue within a soft tissue matrix. Specifically, the process and apparatus provides a transmissive ultrasonic holography imaging system having an acoustical opaque small element variably placed so as to block from being transmitted into an image plane that portion of the transmitted sound that is not scattered by the object. Alternately, the process and apparatus provides for an acoustical opaque plane with an opening variably placed so as to block from being transmitted into an image plane that portion of the transmitted sound that is scattered by the object. Alternately, the process and apparatus provide for an acoustically opaque element in the shape of a plane with an circular openings variably placed so as allow passage only that portion of the transmitted sound that is scattered by the object at a selected location within the focal plane of the lens means. The inventive process provides for improved imaging visualization of subtle structures within objects (e.g., breast cancer within breast tissue) due to sound scatter from subtle structures within objects because only ultrasound waves that interfere with the object are transmitted to an image plane. More specifically, there is disclosed a process to selectively use and display only that portion of imaging sound that diffracts, refracts or scatters from the internal structure of the object. Further, there is disclosed a process to separately use only specific portions of the transmitted sound wave to make separate images of the object and utilize a combination of such images to provide greater detailed information about subtle structures within the object.
