Abstract: A fluoroscopic imaging apparatus is provided. The apparatus includes an x-ray source for projecting x-rays through a subject. The x-ray source has a voltage and a current associated therewith. The apparatus also includes an x-ray detector for detecting radiation which has passed through the subject and a monitor for displaying an image indicative of the detected radiation. The image defines a field of view. In addition, the fluoroscopic imaging apparatus includes an operator interface for selecting a region of interest within the field of view. In response to image data within the region of interest, an image of the region of interest can thereafter be enhanced.

Abstract: A marinating apparatus for marinating food products to induce flavoring agents into food products. The marinating apparatus includes a housing with a marinating compartment that has motorized supports for supporting a perforated food tray that permits the user to raise and lower the food in and out of the marinade. A heating element for warming the food, along with the necessary controls for activating it. A vacuum pump for evacuating the air from the marinating compartment and the associated controls. A timer device for controlling the process.

Abstract: A subject is positioned on a patient support (12) between an x-ray source (10) and a radiation detector assembly (14). The x-ray source is gated (36) on or open prior to triggering (38) a video camera (26) of the x-ray detector assembly to generate an electronic frame image representation. The patient support is moved to generate reference images at positions (5, 4, 3, 2, 1) and the resultant reference images are stored in a reference image memory (42). A radiopaque dye is injected adjacent a first position (1) and the x-ray source and camera are triggered at a first rate indicated by a scan program memory (50). The generated images are displayed on a video monitor until a radiologist decides that the radiopaque dye has moved downstream sufficiently that it is time to index to a second position (2). The radiologist presses an index button (68) causing the patient to be indexed.

Abstract: X-ray equipment for nondestructive testing and particularly for mechanized testing of the integrity of welds along the length of the welds includes means for mechanically traversing an X-ray source along one side of the weld and a grainless fluorescent screen along the other side, with the screen coupled to an image-isocon video camera, preferably through a light intensifier. The equipment includes means for display of the X-ray shadow picture from the video camera and for super-imposing identifying indicia, along with means for recording the composite of the indicia and the picture. The image is preferably integrated over at least several frames so as to minimize "noise" and intensify contrast. In addition, a signal from an ultrasonic transducer may be provided to indicate to the operator the existence of a probable flaw in the weld metal.

Abstract: An X-ray machine for production line inspection of tires places each tire in turn with one sector of the tire inside of a U-shaped arrangement of three fluorescent screens so that one screen faces the tread and the other two face the sides of the tire. An X-ray source inside the bead circle of the tire produces X-ray shadow pictures on the screens, which are separately viewed by a video camera, with an image of the picture on each screen transferred to a third of the target of a storage tube, so that a composite image of the entire width of the tire sector can be displayed on a picture tube. The tire is rotated stepwise for display of still pictures of every sector of the tire.

Abstract: An X-ray tire inspection machine for rapid and precise determination of accuracy of placement of internal elements, by visual or automated sensing of dimensions and of uniformity, precisely places each of a random succession of pneumatic tires for highway vehicles from the smallest to the largest sizes, scans the entirety of bead-to-bead sectors or any part of each sector, without gaps or significant overlaps, and displays all or any desired portions of the X-ray shadow pictures as a succession of still pictures, or senses automatically the presence of irregularities of various kinds in any desired locations. Precise placement of tires is accomplished by gripping of the tread of a horizontal tire by four spools having upper and lower flanges positively moved toward one another at a fixed speed until they grip the shoulders of the tread.
