1. A medical instrument for scanning the anatomy with a beam of radiation, the medical instrument comprising:

  • a medical instrument portion that is insertable into a portion of the anatomy; and

    a module, the module comprising;

    a housing suitable for insertion in the anatomy that includes a window and a fastener to attach the housing to the medical instrument portion such that the module is carried along with the insertable portion of the medical instrument;

    an oscillating reflector within the housing that directs a beam of radiation onto the anatomy; and

    a radiation collector to receive radiation returned from the anatomy including a detector or collecting fibers connectable to a detector;

    wherein the fastener is a linkage having a distal end and a proximal end, wherein the distal end of the linkage is attached to the module and the proximal end is pivotally attached to the medical instrument portion;

    wherein the linkage comprises first linking members and second linking members disposed on each side of the medical instrument, the first linking members including a shape memory alloy actuator capable of applying a lifting force to move the module by pivoting the linkage about its proximal end.
