Abstract: Method of automatically generating a construction specification that is immediately viewable and editable in real time, online. Construction project information can be automatically extracted from a CAD drawing or from a checklist that is filled out online, and a project specification based on a standardized base document automatically generated.

Abstract: A method and device for three dimensional ultrasonic scanning of a patient is described by which an ultrasonic probe scans image planes oriented in a wedge or fan shaped volume. The probe is moved in an arc of travel about an apex which is below the scanning device and may be adjustably located within the probe or lower, such as between the ribs of the patient. The inventive method and device enable a significant volume of the heart to be scanned intercostally and viewed in a three dimensional image format.

Abstract: An ultrasonic probe assembly in which the disposition of the scan plane of an ultrasonic transducer is achieved using a linear actuator. The scan plane is selected by operation of a remote control unit which, through cables, controls the linear actuators and associated gears and, thus, the rotation of the ultrasonic transducer.

Abstract: An ultrasonic probe assembly in which an ultrasonic transducer is mechanically scanned in response to a drive motor which is located in a housing spaced from the transducer such that the transducer can be positioned in a body cavity of patient while the housing containing the drive motor remains outside the body of the patient.

Abstract: An ultrasonic probe assembly in which the disposition of the scan plane of an ultrasonic transducer unit, introduced into a human body, can be selected to image a body part in different ways. The scan plane is selected by operation of a remote control unit by which the ultrasonic array is moved. The ultrasonic array is mounted to a base unit for pivotal movement relative to the base unit and is steered by the action of a cable which is controlled by the remote control unit.

Abstract: An ultrasonic probe assembly in which the disposition of the scan plane of an ultrasonic transducer unit, introduced into a human body, can be selected to image a body part in different ways. The scan plane is selected by operation of a remote control unit by which the ultrasonic array is moved. The ultrasonic array is connected to a base unit by means of a flexible coupling and is steered by the action of cables which are controlled by the remote control unit.

Abstract: A transesophageal echo cardiography probe includes a cylindrical housing (1) and end cap (2), a rotatable axle (10) extending longitudinally along the housing, a motor (7) operable for rotating the axle (10), and a multielement ultrasonic transducer array (5) carried on and for rotation with said axle (10) for emitting an ultrasonic imaging beam. The array elements (5A) are connected to a flexible, first flat cable (11) that extends, preferably in an S-like undulating manner, radially-outwardly toward the end cap wall. The radially-outward end of the first cable (11) is connected to a second flat cable (12) which extends longitudinally along the housing (1) to the rearward end of the housing. The second cable (12) has an arcuate cross-sectional shape for facilitating its receipt in and extension through an arcuate passageway defined between the motor (7) and the inner periphery of the housing (1).

Abstract: An ultrasonic imaging system having imaging and Doppler displays. The imaging and Doppler transducers are scanned simultaneously and the Doppler transducer is stopped and triggered at a selected angle of its oscillation.

Abstract: A novel display method and system for electroencephalographic data includes the use of a linear array of picture elements whose distance from each other is inversely proportional to the power of the EEG signal at a given frequency. The display indicates relative proportions of power over a range of frequencies of interest.

Abstract: An array of acoustic transmit/receive transducers is placed near the body to be imaged. Acoustic energy is projected upon the body sequentially from different ones of the transducers, each projection covering the entire scene or field of view which it is desired to image. The electrical signals produced from reflected acoustic energy picked up by different transducers are phase shifted, or time delayed as appropriate, so that those from any particular point within the body will additively combine in amplitude, while signals from other points will not. In so doing, there is preserved not only the information about the amplitude of the combined signal from the transducers, but also any information about phase shifts (or time delays as the case may be) which does not result in complete alignment of the signals from the different transducers. The resulting complex signals are further processed, to vectorially add them.
