Patent number: 8154797Abstract: A surgical microscope has an illuminating arrangement for illuminating light in an operating region to be examined with the surgical microscope. The arrangement contains a high-power light source which includes an intensity adjusting device. The device makes possible an adjustment of the intensity of the illuminating light, which is guided to the object region, between a maximum value and a minimum value. The microscope has a control unit for the illuminating arrangement which includes an operator-controlled module via which the illuminating arrangement can be activated and controlled. For adjusting the intensity of the illuminating light guided to the operating region, the control unit coacts with the adjustable filter unit. A signal generator outputs a warning signal when an intensity of the illuminating light is adjusted via the operator-controlled module which exceeds the safety limit value stored in a memory.Type: GrantFiled: March 18, 2011Date of Patent: April 10, 2012Assignee: Carl Zeiss Meditec AGInventors: Joachim Steffen, Michael Haisch, Frank Rudolph, Martin Schneider, Hans-Joachim Miesner, Nicole Brune

Publication number: 20110028850Abstract: A method for the quantitative representation of the blood flow in a tissue or vascular region is based on the signal of a contrast agent injected into the blood. In the method, several individual images of the signal emitted by the tissue or vascular region are recorded at successive points in time and are stored. Based on the respective signal, a quantity characteristic for the blood flow and a quantity characteristic for the position of the blood vessels are determined for image areas of individual images. These quantities are represented superimposed for the respective image areas such that both the blood flow quantity and the position of the fine blood vessels become clearly visible in the representation and can be differentiated from the tissue.Type: ApplicationFiled: July 28, 2009Publication date: February 3, 2011Inventors: Thomas Schuhrke, Guenter Meckes, Joachim Steffen, Hans-Joachim Miesner, Frank Rudolph, Werner Nahm
