Abstract: A catheter delivery device having an improved mechanism for inserting a catheter into a blood vessel of a patient. The catheter delivery device includes at least: a body including a delivery path of a catheter; a pair of feeders having grippers located on the delivery path of the body and are configured to grip and release the catheter; and a rotator configured to rotate the catheter gripped by the feeders. The feeders move from a grip position where the grippers grip the catheter to a forward position where the grippers advance in a state of gripping the catheter, from the forward position to a grip release position where the grippers release the catheter, from the grip release position to a backward position where the grippers retract in a state of releasing a grip on the catheter, and from the backward position to the grip position.

Abstract: A method of joining a high entropy alloy is provided. The method of joining a high entropy alloy includes the steps of: arranging specimens made of a high entropy alloy to be in contact with each other; and diffusion joining the specimens made of the high entropy alloy by simultaneously applying a compressive stress and a current to a joint of the specimens within a range in which the high entropy alloy does not melt.

Abstract: Disclosed are a radiotherapy assistant apparatus for modulating a build-up region of a photon beam for a radiotherapy, a radiotherapy system including the radiotherapy assistant apparatus, and method for the radiotherapy system. The radiotherapy assistant apparatus for modulating a build-up region of a photon beam for a radiotherapy, including at least: a magnetic field generator that generates a magnetic field that has a direction perpendicular to a movement direction of the photon beam, the magnetic field generator is disposed on a movement route along which the photon beam moves toward a target portion of the radiotherapy; and a magnetic field intensity adjuster that adjusts an intensity of the magnetic field generated by the magnetic field generator. The magnetic field generator disperses secondary electrons that have particular energy levels equal to or lower than a preset value.
