Description of the Related Art Ultrasound examinations are indispensable in modern medical treatment, and those who perform examinations are required to have high knowledge, experience, and skills. At present, education and training of persons who perform examinations are conducted at medical institutions such as hospitals while conducting actual examinations of patients under instructors who have extensive knowledge and experience. Therefore, there are considerable limitations on the training time and the illnesses experienced. However, no phantom for ultrasonic medical training currently exists. However, there are models using agar, gelatin, etc. for the purpose of evaluating the performance (spatial resolution, density resolution, etc.) of the ultrasonic apparatus, but none of them reproduces the shape or internal structure of a human body organ. Also, due to the nature of the material,
Stable performance could not be maintained for a long time.

用人体モデル によって構成される。According to the present invention, there is provided an organ model obtained by molding and curing liquid silicone rubber and changing the color tone of an image processing monitor by ultrasonic waves applied to the molded and cured product. A human body model for ultrasonic medical training built in a human body model made of silicone rubber, wherein the molded and cured product is a bag, and an internal organ model in which water or a water-like liquid is sealed and sealed in the bag is described. Ultrasound medical training human body model Liquid silicone rubber is mixed with relatively uniform fine particles and molded and cured, and by changing the concentration of the fine particles, the color tone of the image processing monitor by the ultrasonic wave applied to the molded cured product is changed. The human body model for ultrasonic medical training according to the first aspect of the present invention, which incorporates a built-in organ model. The ultrasonic medical training human body model is constituted by the ultrasonic medical training human body model according to the third or fourth invention, wherein the color tone is changed by a combination of the fine particles and the fine fibers.

て臓器の形状に成形硬化させることができる。BEST MODE FOR CARRYING OUT THE INVENTION Liquid silicone rubber hardens at room temperature with almost no shrinkage by adding a hardener or only by contact with moisture in the air, and becomes a rubbery material. It cures to a rubbery state. By utilizing this property, it can be molded and hardened into the shape of an organ.

色調は投入超音波の反射がなく吸収されるためである。As long as no bubbles remain, the molded cured product 1 appears black on a monitor when subjected to image processing by applying ultrasonic waves, and the state can be visually recognized. This black color is absorbed because there is no reflection of the input ultrasonic wave.

からの反射波を捕捉することによって起る現象である。Therefore, a cured product 1 formed by uniformly mixing fine particles having a relatively uniform size with the above liquid silicone rubber 1
When an ultrasonic wave is applied to the black, the color tone of the black color changes toward white depending on the concentration of the fine particles. This is a phenomenon caused by capturing a reflected wave of the ultrasonic waves from the fine particles.
