摘要： Described herein is a transfer device that transfers a visualized image formed on an image carrier onto a recording medium. The transfer device includes an image carrier that carries a toner image, a contacting member that contacts the image carrier via a recording medium and a power source that outputs a transfer bias to transfer the toner image from the image carrier onto the recording medium at a transfer nip formed between the image carrier and the contacting member. The transfer bias has a direct current component and an alternating current (AC) component superimposed on the direct current component. The transfer device also includes a controller that controls the power source such that the controller controls a level of the direct current component output from the power source by a constant current control.

摘要： An image forming apparatus includes an image carrying member to carry a toner image, a nip forming member to form a transfer nip with the image carrying member, and a transfer bias outputting unit to output a transfer bias to transfer the toner image from the image carrying member to a recording medium. The transfer bias is composed of a direct current (DC) component and an alternating current (AC) component, and a least one of the DC component and the AC component is subjected to constant voltage control. When constant current control is conducted at a timing other than when the toner image is being transferred from the image carrying member to the recording medium, a detection bias voltage at the transfer nip is detected, and the voltage of at least one of the DC component and the AC component is controlled based on the detected detection bias voltage.

摘要： A virtual field of view of a virtual endoscope, which is positioned at a position corresponding to a detected position of an endoscope in a 3D medical image, is determined based on a position of a structure of interest, the corresponding position and a posture of the endoscope, and an angle of view of the endoscope, such that the position of the structure of interest is contained within the virtual field of view and the virtual field of view has continuity with the field of view of the endoscope. From the 3D medical image inputted, a virtual endoscopic image having the determined virtual field of view with the view point thereof being the corresponding position of the endoscope is generated. The generated virtual endoscopic image is displayed on a WS display.

摘要： A target-viewpoint position in a first-medical-image having multiple viewpoints is determined. Information about an anatomical structure and/or a lesion in the first-medical-image is obtained, as first information. Further, information about an anatomical structure and/or a lesion in a finding with respect to at least one second-medical-image of the same examined person as the first-medical-image, the information being related to the first information, is obtained, as second information, from image-reading-report information including the finding. Each of the at least one second-medical-image has multiple viewpoints, and was obtained at different time from the first-medical-image. The image-reading-report information is correlated with an image of a viewpoint position at which the finding was prepared. An image of a corresponding viewpoint position, which corresponds to the target-viewpoint position, is determined based on the viewpoint position of the image correlated with the image-reading-report information from which the second information has been obtained.
