  • Patent number: 9002058
    Abstract: An imaging system (100) includes a housing (101). A control circuit (224) disposed within the housing (101). A projector (102) is disposed within the housing (101) and is operable with the control circuit (224). The projector (102) is configured to create images (104) with an image cone (106). A gesture recognition device (103) is disposed within the housing (101) and is operable with the control circuit (224). The gesture recognition device (103) is configured to detect gestures (107) in a gesture recognition cone (108). The projector (102) and the gesture recognition device (103) can be arranged within the housing (101) such that the image cone (106) and the gesture recognition cone (108) exit the housing (101) without overlap.

  • Publication number: 20050020898
    Abstract: According to one embodiment, the invention relates to a method of configuring a scan in an imaging device comprising the steps of beginning a data acquisition step for a first scan, during the data acquisition step for the first scan, completing a data entry step relating to a second scan, completing the data acquisition step for the first scan, and beginning a data acquisition step for the second scan. The invention also relates to an imaging system comprising a detector which detects radiation during a data acquisition step of a scan, at least one processor which controls configuration and execution of the scan, and at least one memory which stores at least one computer program for executing the scan and data for configuration of the scan, wherein the processor is programmed to conduct the data acquisition step for a first scan, and during the data acquisition step for the first scan, conduct a data entry step for a second scan.
