Publication number: 20230410981Abstract: A medical image display system is a medical image display system that displays a medical image. The medical image includes an image in which at least one annotation indicating a detection result of at least one anatomical structure shown in a captured image of a subject is superimposed on the captured image. The medical image display system includes: a display that displays the medical image; and a controller that, when a size of an annotation indicating an anatomical structure having an abnormality among the at least one annotation is less than a threshold value, causes the display to superimpose a probabilistic atlas indicating a normal structure assumed in a case where the anatomical structure having the abnormality is normal, on the captured image.Type: ApplicationFiled: November 15, 2021Publication date: December 21, 2023Inventors: Tomoharu NOTOSHI, Masahiro ISHII, Kenji KONDO, Hirohiko KIMURA, Toyohiko SAKAI, Masato TANAKA, Shinichi FUJIMOTO

Patent number: 11250048Abstract: Similar medical images having a predetermined similarity to a region of interest in a medical image to be interpreted are received from a case search system. A display screen on which the received similar medical images are displayed is displayed on a display. The display screen includes display frames within which similar medical images are displayed. In response to an instruction for enlarging the similar medical images, corresponding regions of interest in the similar medical images are enlarged and displayed with the sizes of the display frames maintained unchanged on the display screen. In response to an instruction for causing a selected similar medical image among the enlarged and displayed similar medical images to move within a corresponding display frame, the other unselected similar medical image(s) is caused to move within a corresponding display frame synchronously with the movement of the selected similar medical image in the same movement direction.Type: GrantFiled: November 3, 2020Date of Patent: February 15, 2022Assignee: PANASONIC CORPORATIONInventors: Kazuki Kozuka, Kazutoyo Takata, Kenji Kondo, Hirohiko Kimura, Toyohiko Sakai

Patent number: 10984907Abstract: If a lesion included in a specification target image is a texture lesion, a probability image calculation unit calculates a probability value indicating a probability that each of a plurality of pixels of the specification target image is included in a lesion area. An output unit calculates, as a candidate area, an area including pixels whose probability values are equal to or larger than a first threshold in a probability image obtained from the probability image calculation unit and, as a modification area, an area including pixels whose probability values are within a certain probability range including the first threshold. An input unit detects an input from a user on a pixel in the modification area. A lesion area specification unit specifies a lesion area on the basis of the probability image, the candidate area, the modification area, and user operation information.Type: GrantFiled: June 13, 2019Date of Patent: April 20, 2021Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kensuke Wakasugi, Kenji Kondo, Kazutoyo Takata, Hirohiko Kimura, Toyohiko Sakai
