A circuit board design uses CMOS sensors for the tip section of a multi-viewing element endoscope. Side sensors and their optical assemblies are assembled to a common base board to save space. Individual base boards are separately constructed, inserted into grooves of a main base board, and are further connected to the main base board by means of flexibal circuit boards.
Reduction of image lag in an X-ray detector panel
A radiation therapy system is configured with fast readout of X-ray images with significantly reduced image lag. A reset phase is included in the process of acquiring an X-ray image to reduce image lag in a subsequently acquired X-ray image. During the reset phase, residual charge is concurrently transferred from multiple arrays of pixel detector elements in an X-ray detector panel. As a result, image lag present in a subsequent X-ray image is minimized or otherwise reduced.

VEHICULAR MULTI-CAMERA SURROUND VIEW SYSTEM WITH VIDEO DISPLAY
A vehicular multi-camera surround view system includes a front camera, a driver-side camera, a passenger-side camera and a rear backup camera. Image data captured by the cameras is conveyed to an electronic control unit. The electronic control unit is operable to combine image data conveyed from the front camera, the driver-side camera, the passenger-side camera and the rear backup camera to form composite video images, which are output for display at a display device. Rear backup video images are displayed no later than two seconds after the driver of the vehicle first changes propulsion of the vehicle during a new ignition cycle to reverse mode. Upon changing propulsion of the vehicle during the new ignition cycle to reverse mode to commence a backup event subsequent to the first backup event, the video display screen displays video images derived, at least in part, from image data captured by the rear backup camera.
