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： There is disclosed a method for non-invasively determining dimensions of a lesion within soft tissue, comprising: (a) ultrasonically imaging soft tissue in an apparatus having an acoustic transducer, an acoustic focussing system, a holographic imaging detector, and a means for visualizing the holographic image; (b) obtaining a holographic planar image of a lesion in a first plane having a thickness z and having a dimension across a wide area of the lesion of x and a length across the lesion of y wherein y is at an approximately 90 degree angle to x; (c) determining if the image of the lesion is contained in different planar images; (d) measuring the x and y dimensions of the lesion in the plane having the largest sum of x plus y dimensions; and (e) determining the 3-dimensional size with a means for z-axis measurement.

摘要： A tissue biopsy device uses ultrasonic imaging to guide the biopsy needle. An ultrasonic imaging device comprises three acoustically coupled chambers with an ultrasound transducer in a first chamber, at least a portion of an ultrasound detector in the second chamber and the portion of patient anatomy to be imaged placed in the third chamber, which is intermediate the first and second chambers. The three chambers are filled with an acoustically transmissive liquid. One or more of the end walls dividing the first and third chambers and second and third chambers may be movable to form compression plates that are used to retain the patient anatomy in a fixed position during the imaging and biopsy process. When a structure, such as a lesion, has been located, the imaging may be used to determine the precise location of the lesion in three dimensions. The ultrasonically transmissive fluid is drained from the central third chamber with ultrasonic coupling occurring through the ultrasonically transmissive compression plates and the imaged patient anatomy. This permits real-time imaging of the patient anatomy during the biopsy process. The three-dimensional coordinates are used to provide a manual guide for insertion of the biopsy needle. Light bars may be projected onto the external anatomy of the patient to indicate the desired point of entry of the biopsy needle. The physician may use the real-time imaging to view both the lesion and the biopsy needle. In an alternative embodiment, a biopsy needle may be automatically positioned at the location of the lesion by a three-dimensional positioning system.
