摘要： A transesophageal echocardiographic scanner includes a rotatable transducer for rotating the image plane of the scanner. The transducer is a circular shaped array of parallel oriented elements which may be operated as a phased or linear array. The transducer is mounted on a bell-shaped backing box with a conical interior surface that directs reverberations from the back of the transducer into damping material which fills the box. The transducer is located in a fluid compartment which is divided by a cover member into an ultrasonic transmission region between the emitting surface of the transducer and the cover, and an adjacent bubble trap region into which bubbles may pass and preferentially remain.

摘要： An ultrasonic transesophageal scanhead is provided which enables a physician to easily and quickly change the orientation of the image plane during a scanning procedure. Means are provided on either the scanhead or the ultrasound system for selecting the imaging plane. As the imaging plane selector is actuated, an indication of the orientation of the selected plane appears concurrently on the monitor of the system along with a display of ultrasonic information of the selected plane. In a preferred embodiment the indication of the selected plane is displayed both graphically and numerically. A recording of the displayed information will thus capture both the ultrasonic information as well as the image plane orientation. A physician reviewing the recording will thereby know the exact orientation of the image being viewed, leading to a better informed and more precise diagnosis of medical conditions of the body.

摘要： An ultrasonic transesophageal scanhead is provided which enables a physician to easily and quickly change the orientation of the image plane during a scanning procedure without disrupting control of the scanhead. Means are provided on the external control unit of the scanhead for unambiguously selecting the orientation of the plane which is imaged by the transducers at the end of the probe of the scanhead. In one embodiment of the present invention, a rocker switch is provided on the underside of the control unit, and a lighted indicator is provided on top of the control unit. When the physician desires to change the image plane, the rocker switch is rolled forward to select the transducer elements of the probe which are configured for scanning in the desired image plane. As the rocker switch is moved, the lighted indicator on the top of the control unit provides a visual display pattern aligned either longitudinally or transversely with respect to the axis of the probe. Thus, the physician can change scanning planes without moving his hand from the control unit, and the unit constantly provides an indication of the orientation of the selected plane.

摘要： A device for unloading exposed film from a cassette, discarding a backing strip which is wound with the film, discharging the cassette body and conveying the film to a light-free storage box. The cassette is initially loaded into the device through a shutter-closable aperture and received by a downwardly inclined cradle. Upon initiation of the loading cycle, the loading aperture shutter closes and a pneumatic ram lifts the cradle to place the cassette against the inlet of a film guide. A motor raises a violator probe after the cassette is in place to guide the backing paper between a pair of powered rollers which draw the backing strip from the cartridge thereby carrying the film into the film guide. The backing strip is discharged through a series of ducts to be discharged outside the machine. Film entering the guide is directed past the storage box by a pair of pivotally mounted guide doors which open when the leading edge of the film reaches a downstream optical sensor to allow film to enter the storage box. After all of the film has been removed from the cassette and processed by downstream splicer mechanisms, the cassette cradle is lowered and the cassette is discharged through a series of ducts outside the machine. The loading aperture shutter then opens to receive a new cassette. If the backing strip fails to draw the film from the cassette, the film is automatically rewound into the cassette, the cradle is lowered and the cartridge is routed into a light-free bag instead of the discharge receptacle.
摘要翻译： 用于从盒中卸载曝光的胶片的装置，废弃用胶卷卷绕的背胶条，排出盒体并将胶卷输送到无光储存盒。 盒子最初通过可闭锁的孔被装载到装置中并被向下倾斜的支架接收。 在加载循环开始时，装载孔径快门关闭，并且气动拉杆提升托架以将盒子放置在胶片导板的入口上。 在盒子就位之后，电动机引起违规者探针，以将背纸引导到一对动力辊子之间，从而将背衬带从盒中拉出，从而将胶片携带到胶片导板中。 背衬带通过一系列管道排出，以排出机器外部。 进入引导件的胶片通过一对可枢转地安装的引导门被引导通过存储盒，导向门当胶片的前缘到达下游光学传感器时打开，以允许胶片进入存储盒。 在所有的胶片已经从盒子中取出并通过下游捻接机构处理之后，盒式支架被降低，并且盒式磁带通过机器外部的一系列导管排出。 装载光圈快门然后打开以接收新的盒式磁带。 如果背带无法从胶卷盒中拉出胶片，则胶片会自动重新卷入胶卷盒，将底座放下，将胶卷放入轻便的包装袋中而不是放电容器。
