摘要： An acoustic matching device has a water bag (64) that contains water and a water bag support frame (66) that sandwiches and supports the water bag on the left and right sides of the knee and curves along the knee cap. The water bag becomes a plate shape curved along the shape of the water bag support frame, which touches the knee cap and fits the unevenness of the knee. When an ultrasonic probe is moved along the knee cap, the acoustic matching between the knee cap and the ultrasonic probe is obtained.

摘要： An ultrasonic beam (40) for echo tracking is formed for a healthy portion (52a) of a bone (50) containing healthy portions (52a, 52b) and a fractured portion (54). Echo tracking processing is executed over the state where a load F is not applied to the bone (50) and the state where the load F is applied to the bone (50) so as to calculate a distortion amount of the bone (50) accompanying the load F via the ultrasonic beam (40) formed for the healthy portion (52a). The state of union of the fractured portion (54) is evaluated in accordance with the distortion amount obtained via the healthy portion (52a).

摘要： A mounting unit (16) is aligned by using a mounting unit frame (58) touching the thigh and a knee-contacting portion (62) touching the knee, with the knee being bent. The mounting unit is also equipped with a probe support frame (60) used for moving an ultrasonic probe along the knee cap. The probe support frame moves rotationally about the mechanical center of the knee joint, thereby allowing the ultrasonic probe (78) to move along the knee cap while facing toward the mechanical center of the knee joint and to perform scanning of an ultrasonic beam.

摘要： The present invention provides an ultrasound diagnostic apparatus capable of appropriately evaluating dynamic characteristics of a bone. The ultrasound diagnostic apparatus obtains an interpolated line 52a representing a bone surface shape based on echo signals obtained from ultrasonic beams transmitted to a surface of the bone on which a load is applied. A user inputs an outer diameter φ of the bone which can be stored in a memory. The ULTRASOUND DIAGNOSTIC APPARATUS calculates a distortion ε which represents an expansion/contraction rate in an axial direction on the bone surface to which the load is applied, based on the interpolated line 52a and the bone outer diameter φ. The distortion ε is equal to a ratio defined by x/(x+dx)=r/(r+dr)=r/(r+1/2φ), wherein x represents a length of the bone surface in a measurement range (i.e., length of the interpolated line 52a) and x+dx represents a length of a neutral axis 52b of the bone.

摘要： A surface point tracked by an echo tracking processor unit for each ultrasonic beam is a tracking point. A strain measurement unit measures an amount of strain of a bone based on the surface points. A delay time measurement unit measures a time for the amount of strain of the bone to reach a return reference value, corresponding to a state before a load is applied, after the load is first applied to the bone and then removed.

摘要： An oscillation arm moves in a seesaw fashion about an oscillation axis which is supported by a support rod and which serves as a fulcrum. A rotation arm and a pressurizer are provided on one end of the oscillation arm. One end of the rotation arm is rotatably attached to the oscillation arm, and a load weight is placed on the other end of the rotation arm. By rotating the rotation arm, the magnitude of a force to be applied by the load weight to the pressurizer is adjusted. More specifically, by displacing the load weight to a predetermined position by rotation and then causing the load weight to stop at this position, a static load corresponding to the rotation angle can be applied to the pressurizer. Further, by causing the load weight to perform rotational motion, the magnitude of the force to be applied to the pressurizer is periodically varied, so that a load which varies periodically can be applied to hard tissue.

摘要： There is obtained an MOCVD oriented vaporizer which eliminates a phenomenon that thin-film materials are adhered to a portion of the vaporizer near and around a spout thereof. A carrier gas/small amount oxidizing gas supply part supplies a carrier gas, which is supplied through an internally formed gas passage and which contains a material solution, to a vaporization part; a bubble prevention/material solution supply part supplies a material for preventing generation of bubbles of the carrier gas containing the material solution, and the material solution, into the carrier gas; a solvent vaporization restricting/cooling system restricts vaporization of a solvent; and a swirl flow preventing gas supply part supplies a gas for preventing occurrence of swirl flows near a gas outlet of the vaporization part. An atomizing part causes the carrier gas, which contains the material solution and which is ejected from the vaporizer, to be formed into a finely atomized state; and a complete vaporization oriented high performance vaporization tube completely vaporizes the carrier gas ejected from the vaporizer and containing the material solution. This enables long-term usage without clogging and the like, and enables a stable material supply to a reaction part.
