Patent number: 9724066Abstract: One embodiment of the present disclosure is directed to a mobile X-ray unit. The mobile X-ray unit may include an X-ray applicator for emitting an X-ray beam for irradiating an object. The mobile X-ray unit may further include a phantom-based dosimetry system configured to perform a dosimetry check of the X-ray beam. The phantom-based dosimetry system may include two sets of dose meters, each set being positioned on a surface at a distinct depth. The mobile X-ray unit may also include a dosimetry control unit configured to receive measurements from the two sets of dose meters and determine whether the dosimetry check is passed based on the measurements.Type: GrantFiled: August 8, 2014Date of Patent: August 8, 2017Assignee: Nucletron Operations B.V.Inventors: Johannes Simon Van Der Veen, Bas Woudstra, Johan Henning

Patent number: 9393446Abstract: One embodiment of the present disclosure is directed to a mobile X-ray unit. The mobile X-ray unit may include a base for accommodating a control unit for controlling an X-ray applicator and a power supply for supplying power to the X-ray applicator. The mobile X-ray unit may further include an articulated arm associated with the base and coupled to the X-ray applicator. The X-ray applicator may have an X-ray tube configured to emit an X-ray beam through an exit window to irradiate an object. The mobile X-ray unit may further include a dosimetry system adapted for real time dosimetry.Type: GrantFiled: March 2, 2015Date of Patent: July 19, 2016Assignee: Nucletron B.V.Inventors: Johannes Simon van der Veen, Bas Woudstra, Johan Henning

Patent number: 7369891Abstract: The invention is directed to rate control techniques for implantable pulse generator (IPG) systems. The techniques make use of a plurality of timing intervals that may replace conventional rate control and allow “double-pacing” pulses to be delivered in certain instances. For example, a second pulse, i.e., a “double-pacing” pulse, may delivered within a first time interval relative to delivery of the first pulse. However, the second pulse is not allowed once the first time interval has elapsed, if a second time interval has not also elapsed. If the second pulse is delivered during the first time interval, then the second time interval is restarted and another pulse cannot be delivered until the restarted second time interval has elapsed.Type: GrantFiled: April 23, 2003Date of Patent: May 6, 2008Assignee: Medtronic, Inc.Inventors: Frederik Augustijn, Johannes Simon van der Veen, Lucas Johannes José Marie Meekes
