Disclosed is a marking method for marking a radiation therapy positioning note, comprising in sequence: a preparing step of providing a radiation therapy positioning sticker, wherein the radiation therapy positioning sticker includes a pattern layer and a release layer disposed on an outer surface of the pattern layer, and the radiation therapy positioning note is formed on the outer surface of the pattern layer; a transferring step of attaching the radiation therapy positioning sticker onto a predetermined note position of a radiation therapy target object in a manner that an inner surface of the pattern layer faces forward the predetermined note position and covers the predetermined note position; and a removing step of peeling off the release layer from the outer surface of the pattern layer to outwardly expose the radiation therapy positioning note, which is formed on the outer surface of the pattern layer covering the predetermined note position.

An ultrasonic diagnostic apparatus for assisting insertion of a puncture needle into a subject, includes: an ultrasonic probe that is arranged to allow a probe distal end part to be pressed against a body surface of the subject, and acquires an ultrasonic image of an inside of the subject by transmission and reception of an ultrasonic wave; an optical camera that is attached to a proximal end side of the probe and captures an image of an arrangement position of the probe distal end part of the probe on a body surface; and a laser pointer that is attached to a proximal end side of the probe and emits laser light onto a body surface to form a predetermined projection image, to guide a target insertion position and a target orientation of the needle when the needle is inserted into the subject, in an optical image acquired by the camera.

An ultrasonic probe comprising a housing, a first ultrasonic transducer array, a second ultrasonic transducer array, a first light source, and a second light source. The first ultrasonic transducer array is coupled to the housing and configured to emit a first planar ultrasonic beam in a first direction within a first plane. The second ultrasonic transducer array is coupled to the housing and configured to emit a second planar ultrasonic beam in the first direction within a second plane, which is substantially perpendicular to the first plane. The first light source is coupled to the housing and configured to project a first light line substantially within the first plane. The second light source is coupled to the housing and configured to project a second light line within a third plane, which is substantially perpendicular to the first plane and intersects the second plane at an oblique angle. The first light line intersects and is substantially perpendicular to the second light line.

A surgical implant planning computer is connectable to a fluoroscopy imager, a marker tracking camera, and a robot having a robot base coupled to a robot arm that is movable by motors relative to the robot base. Operations include performing a registration setup mode that determines occurrence of a first condition indicating the marker tracking camera can observe to track reflective markers that are on a fluoroscopy registration fixture of the fluoroscopy imager, and determines occurrence of a second condition indicating the marker tracking camera can observe to track dynamic reference base markers attached to the robot arm and/or an end-effector connected to the robot arm. While both of the first and second conditions occur, operations are allowed to be performed to obtain a first intra-operative fluoroscopic image of a patient along a first plane and to obtain a second intra-operative fluoroscopic image of the patient along a second plane that is orthogonal to the first plane.
