Medical imaging is for medical or medical research, on the human body or a part of the human body, non-invasive way to obtain internal tissue image technology and processing, medical imaging equipment is to obtain medical images of medical equipment and equipment.
Second, what are the medical imaging equipment
Modern hospitals to check the human body, a variety of medical imaging equipment is indispensable, common medical imaging equipment are:
1, CT
that is, computed tomography, the use of precise collimated X-ray beams, gamma rays, ultrasound, and other, and highly sensitive detector with a part of the human body for one by one, and then the body is a part of the human body to make a one by one, and then a part of the human body for one by one. A part of the body for a cross-section scanning, with fast scanning time, clear images and other characteristics, can be used for a variety of diseases, according to the different rays used can be divided into: X-ray CT (X-CT), ultrasound CT (UCT) and γ-ray CT (γ-CT) and so on.
2, MRI
that is, magnetic *** vibration, is the use of magnetic *** vibration phenomenon made of a class of imaging equipment used for medical examinations, can be made directly cross-section, sagittal plane, coronal plane and a variety of oblique layers of the body image, will not produce artifacts in the CT test; angiography (MRA) does not need to be injected into the contrast agent; non-ionizing radiation, no adverse effects on the body.
3, CR
that is, computed radiography system, is the use of light to stimulate the storage of fluorophores as a detector of the X-ray projection imaging method, but also refers to the use of this imaging method of medical imaging equipment.
4, DR
that is, direct digital radiography system, refers to a new technology in the computer-controlled direct digital radiography, the use of amorphous silicon flat-panel detector to penetrate the body of the X-ray information into digital signals, and computer reconstruction of the image and a series of post-processing images.
5, DSA
that is, digital subtraction angiography technology, is a combination of conventional angiography and electronic computer image processing technology. The image processed by DSA makes the image of blood vessels clearer and safer during interventional procedures.
6, b ultrasound
One of the ultrasound examination, that is, B-type ultrasound, the use of ultrasound in the body's tissues of the reflection, refraction and other physical characteristics, through the instrument to receive signals, thereby showing the shape of various tissues and organs to determine the location of the lesion, the nature of the function and the degree of damage.
7, color ultrasound
High-definition black-and-white ultrasound plus color Doppler ultrasound examination equipment.
Three, medical imaging diagnostic center should be equipped with what equipment
Medical imaging diagnostic center is through the medical imaging equipment for medical diagnosis of the patient's medical premises, according to the "medical imaging diagnostic center of the basic standards (for trial implementation)" and "medical imaging diagnostic center management specification (for trial implementation)", a qualified medical imaging diagnostic center should be equipped with:
1, Basic equipment
At least two digital radiography systems (DR), one each of 16-row CT and 64-row CT and above, and one 1.5T and above MRI system; three ultrasound units with color Doppler blood flow imaging, cardiac ultrasonography, ultrasonography, and quantitative analysis; and two electrocardiographs. It is equipped with oxygen supply device, negative pressure suction device, cardiac monitor and occupational protection items to meet the work needs.
2, first aid equipment
Each radiological examination room must be equipped with a sufficient number of radiation protection supplies and basic rescue equipment to meet the requirements, CT examination room must be equipped with a defibrillator, simple respirator, oxygen supply device, negative pressure suction device and related drugs.
3, information technology equipment
With information reporting and transmission of network computers and other equipment, configured with the workload of the doctor's diagnostic workstations, with PACS / RIS system and remote consultation information system.
