In fact, the technician is a very embarrassing position, the patient called you a doctor, but in fact you are not a doctor (most of the technicians are medical imaging technology college or 4 years of science degree undergraduate, can not be examined practicing medicine, can only take the line of technicians. Although not a doctor, but the same to toss the emergency bloody trauma patients, you are not the first-line clinical staff, but the treatment of auxiliary departments. Radiology is an important auxiliary examination room in the hospital, in the construction of modern hospitals, radiology is a collection of examination, diagnosis, treatment in one of the departments, clinical departments of many diseases have to be examined through the radiology equipment to achieve a clear diagnosis and auxiliary diagnosis. Radiology equipment generally has ordinary X-ray film machine, computerized radiography system (CR), direct digital radiography system (DR), computerized X-ray tomography (CT), nuclear magnetic **** vibration (MRI), digital subtraction angiography system (DSA) and so on. With the continuous updating of radiological equipment and the expansion of examination content, the medical imaging (radiology) department must implement overall management, unified management of various imaging equipment and diagnosis and treatment of business content, that is: traditional X-ray, CT, MR, intervention, are in the director of the unified leadership and management of the work. Different business techniques can be divided into three groups, namely: diagnostic group; technical group; medical support group. Do medical, technical, auxiliary division of labor clear, clear responsibilities. Diagnostic group consists of diagnostic personnel at all levels; technical group consists of technical and physical mechanical personnel at all levels; medical auxiliary group consists of nurses, registration and image data custodians. Under the unified management of the head of the department, the diagnosis and treatment group and the technical group implement "relative fixation and regular rotation" for each imaging content (traditional X-ray, CT, MR, and intervention), which is conducive to the comprehensive mastery of the professional technology and the cultivation of talents, and achieves the goal of "multi-functionality" in imaging. The goal is to achieve the goal of "multi-specialization" in imaging. Diagnostic group and technical group personnel to implement the conditions of rotation: rotation CT must have more than two years of traditional X-ray practice; rotation MR must have more than two years of CT practice; rotation interventional therapy must be more than two years of traditional X-ray diagnostic practice based on prior training in interventional knowledge.
