Sec.  15.513   Technical requirements for medical imaging systems.

   (a) The UWB bandwidth of an imaging system operating under the provisions of
   this section must be contained between 3100 MHz and 10,600 MHz.

   (b) Operation under the provisions of this section is limited to medical
   imaging systems used at the direction of, or under the supervision of, a
   licensed health care practitioner. The operation of imaging systems under
   this section requires coordination, as detailed in  Sec. 15.525.

   (c) A medical imaging system shall contain a manually operated switch that
   causes the transmitter to cease operation within 10 seconds of being
   released by the operator. In lieu of a switch located on the imaging system,
   it is permissible to operate an imaging system by remote control provided
   the imaging system ceases transmission within 10 seconds of the remote
   switch being released by the operator.

   (d) The radiated emissions at or below 960 MHz from a device operating under
   the provisions of this section shall not exceed the emission levels in
    Sec. 15.209. The radiated emissions above 960 MHz from a device operating under
   the provisions of this section shall not exceed the following average limits
   when measured using a resolution bandwidth of 1 MHz:

------------------------------------------------------------------------
                     Frequency in MHz                        EIRP in dBm
------------------------------------------------------------------------
960-1610..................................................         -65.3
1610-1990.................................................         -53.3
011990-3100...............................................         -51.3
3100-10600................................................         -41.3
Above 10600...............................................         -51.3
------------------------------------------------------------------------

   (e) In addition to the radiated emission limits specified in the table in
   paragraph (d) of this section, UWB transmitters operating under the
   provisions of this section shall not exceed the following average limits
   when measured using a resolution bandwidth of no less than 1 kHz:


------------------------------------------------------------------------
                     Frequency in MHz                        EIRP in dBm
------------------------------------------------------------------------
1164-1240.................................................         -75.3
1559-1610.................................................         -53.3
------------------------------------------------------------------------

   (f) There is a limit on the peak level of the emissions contained within a
   50 MHz bandwidth centered on the frequency at which the highest radiated
   emission occurs, f[M]. That limit is 0 dBm EIRP. It is acceptable to employ
   a different resolution bandwidth, and a correspondingly different peak
   emission limit, following the procedures described in  Sec. 15.521.
