ABSTRACT:
An intraoral dental imaging system employs a service unit having a power supply and a light source, and selectively using a video camera having a plug-in module for releasably connecting the video camera to the power supply, or an x-ray camera having a second plug-in module for releasably connecting the x-ray camera to the power supply. In either case the modules have processing means for producing video output signals. These video output signals may be sent to a wide variety of devices connected to the service unit. For instance, they may be used to display an image on a video monitor, such as a CRT, they may be sent to a printer for printing, and they may be sent to a modem for eventual display at another location. In essence, these video output signals may be sent to any device known in the art. Thus, the plug-in modules are highly portable while allowing for interchangeability within the same service unit, thereby allowing a practitioner to use the modules in multiple operatories. In the intraoral x-ray camera the plug-in module may be connected to a sensing head by an umbilical cord. The sensing head includes a first means for converting x-ray input signals into electrical output signals and forwarding those signals to a video processor within the plug-in module, an x-ray sensor means for detecting x-rays, and a triggering means for triggering x-ray acquisition from a sensor, which enables the first means when x-rays are detected and disabling the first means when x-rays are not detected by the sensor means.
