Abstract: A surgery assistance device includes a true lumen information acquisition unit that acquires three dimensional position information of a true lumen existing in a target blood vessel, a true lumen image generation unit that acquires an angiographic image of the target blood vessel from a flat panel detector (FPD) arranged at a first imaging position and generates a true lumen image representing the true lumen at a position and in a posture corresponding to the angiographic image by using position information of the first imaging position and three dimensional position information of the true lumen, and an image composition unit that generates a composite image by compositing the angiographic image and the true lumen image and outputs the composite image.

Abstract: Disclosed is a mobile terminal apparatus including one or more processors configured to execute a process. The process includes storing content data acquired in a specific mode in a storage, acquiring an address corresponding to authentication information at authentication when the content data are acquired in the specific mode, generating a first mail to which the content data are attached and setting the address in the first mail as a transmission destination, transmitting the generated first mail to the address, and controlling deleting the stored content data and a transmission history of the transmitted first mail.
