Accreditation of Noninvasive Vascular Laboratories at the Massachusetts General Hospital in 1946 and others appeared over the years. The work done focused on research efforts, with little thought about providing routine clinical testing. By the 1960s arterial reconstructive procedures became increasingly frequent and with this development there was有害处 发表于 2025-3-25 08:28:17
Qualifications of the Physician in the Vascular Diagnostic Laboratoryvernmental scrutiny and economic pressures.. In view of these challenges, the qualifications and credentials of physicians who interpret noninvasive diagnostic studies have also taken on additional importance. While the Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL)你不公正 发表于 2025-3-25 13:06:13
Principles and Instruments of Diagnostic Ultrasound and Doppler Ultrasound when you are reading it, if history is our guide, ultrasound instrumentation has taken a great leap forward. In contrast, biological evolution is so slow that anatomy has changed little except for individual sagging and surgery. Physiology has changed only in the ways that our understanding has impsacrum 发表于 2025-3-25 17:36:34
