<p>A modular stylus is provided for use in an ultrasound transcription system, the modular stylus comprising: a proximal subunit (12) which forms a proximal portion of the stylus and a distal subunit (18) which forms a distal portion of the stylus, the proximal and distal subunits being removably detachable from each other, the proximal subunit comprising a proximal subunit body defining a recess (42) for housing a proximal portion of a writing element which may be housed within the stylus, and a contact switch (34) which detects when the writing element is in contact with a writing surface based on a force of a proximal end of the writing element against the contact switch, and the distal subunit comprising a distal subunit body defining a recess for housing a distal portion of the writing element, a distal end of the subunit body including an opening through which a writing tip (22) on a distal end of the writing element extends, and an ultrasound signal transmitter (20) which transmits position signals to the transcription system.</p> |
