Summary

This is the full performance level requiring specialized advanced knowledge and assignments. It is expected to perform the full range of vascular ultrasound procedures - including the most complex and non-routine - and to make appropriate adjustments in established procedures and techniques to obtain the results required for clinical diagnosis and documentation. At this level - the technician would also have the ability to perform intracranial (transcranial) vascular examinations.

Duties

• Duties: a) The Vascular Technologist coordinates a variety of technical procedures that require independent judgment - Ingenuity - and Initiative in the application of non-ionizing high-frequency ultrasonic waves to humans for the diagnosis of disease in the clinic or in the Inpatient unit
• b) Knows and understands the principles of ultrasound and the highly specialized equipment well enough to essentially approve the acceptability or rejectability of each scan - controls technical factors on the ultrasound unit - which will affect time - gain - amplitude - velocity - frequency - attenuation - absorption - reflection - scattering - refraction - and diffraction
• Selects between non-focused - fixedfocus - linear phased array - annular phased array - and Doppler or Power Doppler
• c) Performance of the examination requires proper alignment and position of the patient
• Sets up and adjusts all equipment and manually maneuvers the transducer to perform the exam
• d) Receives and identifies patients - explains methods of procedures - assists movement of patients to and from wheelchairs - carts - tables - positions the patient - and performs examinations requested
• Evaluates the nature of critical and emergency procedures and rearranges priorities to accommodate them
• e) The incumbent performs vascular sonography studies - records - and prepares the processed media for Interpretation by the Staff Radiologist
• S/he will maintain records of patients in the Vista radiology package
• f) As a vascular sonographer - s/he schedules and prepares patients for exams and explains procedures to patients while performing the studies
• g) S/he obtains pertinent diagnostic vascular examinations for the physician - which may be necessary for correlation between the ultrasound scan and clinical history
• h) S/he performs diagnostic vascular examination on multiple areas of the body - including - but not limited to - the abdomen - pelvis - transvaginal - chest - small parts - thyroid - breast - and scrotum
• i) S/he routinely performs vascular studies including central - peripheral and cerebral applications - TCD - Carotid - ABI - arterial duplex - venous duplex - renal artery duplex - and visceral vascular exams of the abdomen
• Regularly performs preoperative upper and lower extremity vein mappings for vascular surgeons - as well as chronic venous Insufficiency studies
• j) S/he assists radiologists with biopsy procedures - determining the location - depth - and the required needle angle for the lesion to be sampled
• k) S/he assists in surgical procedures and fluid aspirations
• This requires performance and knowledge of sterile technique and strict enforcement
• l) S/he differentiates artifacts from normal or pathological processes and recognizes electronic equipment limitations
• m) S/he recognizes a diagnostic scan and consults with the Staff Radiologist to determine the proper diagnosis
• Work Schedule: Monday - Friday - 8AM to 4:30PM Telework: Not Authorized Virtual: This is not a virtual position
