。(Prior art) High-frequency coils that detect magnetic resonance signals in magnetic resonance imaging devices and ultrasound probes that emit ultrasound to a subject or detect reflected ultrasound in ultrasound diagnostic equipment can be used in arbitrary spatial locations. A detector holding device is used to keep the detector stationary or fixed in a certain position. This holding device has a fixing part located at one end to which the detector is fixed, a support part located at the other end to be attached to a magnetic resonance imaging device or an ultrasound diagnostic device, and a space between the fixing part and the support part. and a plurality of connecting elements slidably connected to each other. The connecting elements become flexible by being fitted into each other and slidably connected, and the detector fixed to the fixing part can be stationary or fixed at any position.

う問題がある。By the way, when used in a magnetic resonance imaging apparatus, the connecting element of this holding device needs to be made of non-metal so as not to have an adverse effect on the detection of magnetic resonance signals. Therefore, as this connecting element, a synthetic resin element having a gourd-shaped cross section and having a spherical fitting portion is used. However, this resin element is susceptible to twisting, tension, and bending that occur during detector positioning operations. Therefore, during the positioning operation of the detector, there is a problem that the position of the detector may be shifted due to its own weight, and furthermore, the elements may become disconnected from each other.
