PCT No. PCT/US96/05286 Sec. 371 Date Dec. 18, 1997 Sec. 102(e) Date Dec. 18, 1997 PCT Filed Apr. 17, 1996 PCT Pub. No. WO96/32886 PCT Pub. Date Oct. 24, 1996A surgical method comprises successively orienting an ultrasound transmitter (30) to transmit ultrasound from multiple locations (65) adjacent the skin (32) surface and at each of the multiple locations (65) transmitting ultrasound (30), generating a time base, receiving ultrasound echoes, and determining from the time between transmission and reception the depth beneath the skin of tissue to be treated. The depths of the tissue (36) at the multiple locations are stored in a memory (40) associated with a programmable machine (34). The laser (50) is successively targeted on each of the multiple locations (65), and at each of the multiple locations (65) the depth of the tissue (36) to be treated beneath that location (65) is retrieved from the memory (40). The retrieved depth of the tissue (36) to be treated beneath that location determines a laser (50) excitation power that will achieve treatment of the tissue (36) at the retrieved depth. The laser (50) is excited at the determined excitation power. |
