Adjustable hand rest attachment for a musical instrument, wherein the hand rest post is constructed to provide multiple adjustments of the position of the hand rest on which the hand or hands of the musical performer rest when playing a musical instrument, such as a bassoon or contrabassoon. The adjustable hand rest attachment incorporates an articulated hand rest post to allow for varying angles of adjustment. The adjustable positioning of the hand rest achievable through adjustment of the articulated and adjustable hand rest post, reduces discomfort for the player and reduces injury with overuse. The adjustments of the hand rest and the hand rest post may then be secured into a fixed position. A bassoon is equipped with a key mechanism that is constructed using a tube that consists of a tenor joint, a boot (also known as a double) joint, a long joint, and a bell joint. A bassoon weighs approximately 8 pounds and is over 4 feet in length so that support of the instrument by the hands while playing without undue discomfort or fatigue is a significant concern.

A bassoon weighs approximately 8 pounds and is over 4 feet in length so that support of the instrument by the hands while playing without undue discomfort or fatigue is a significant concern. A contrabassoon is equipped with a key mechanism and is constructed using a tube of approximately double the length of the bassoon.

The invention includes a device for detection of respiratory motion of a subject during acquisition of an magnetic resonance image that includes a lever having a proximal and a distal end, a counterweight on the proximal end of the lever, a fulcrum, a pickup coil attached to the distal end of the lever, and a MRI machine that has a radio frequency resonator, a gradient coil, and a magnetic field, wherein the lever, fulcrum, counterweight, and pickup coil are positioned so that the lever moves as the subject breathes, the pickup coil is also positioned so that it does not cause artifacts in the MRI image, and the device as a whole generates an electrical signal that can be used to detect and monitor the respiratory motion of the subject. The invention also includes a device for respiratory gating of a magnetic resonance imaging experiment including a lever having a proximal and a distal end, a counterweight on the proximal end of the lever, a fulcrum, a pickup coil attached to the distal end of the lever, and a MRI machine that has a radio frequency resonator, a gradient coil, and a magnetic field, wherein the lever, fulcrum, counterweight, and pickup coil are positioned so that the lever moves as the subject breathes, the pickup coil is also positioned so that it does not cause artifacts in the MRI image, and the device as a whole generates an electrical signal that can be used to detect and monitor the respiratory motion of the subject and the threshold detector is used to trigger the acquisition of the individual scans of the magnetic resonance image.

The invention includes a device () for detection of respiratory, cardiac, and/or other motion of a subject () during acquisition of an magnetic resonance image that includes a lever () having a proximal () and a distal end (), a counterweight () on the proximal end of the lever, a fulcrum (), a pickup coil () attached to the distal end of the lever, and a MRI machine () that has a radio frequency resonator, a gradient coil, and a magnetic field, wherein the lever (), fulcrum (), counterweight (), and pickup coil () are positioned so that the lever () moves as the subject () breathes, the pickup coil () is also positioned so that it does not cause artifacts in the MRI image, and the device () as a whole generates an electrical signal that can be used to detect and monitor the respiratory motion of the subject (). The invention also includes a device as explained above configured so that the device as a whole generates an electrical signal that can be used to detect and monitor the respiratory motion of the subject and the threshold detector is used to trigger the acquisition of the individual scans of the magnetic resonance image. Another embodiment of the invention does not include the counterweight (), and has the subject () and the pickup coil () on the same side of the fulcrum ().
