Computer is for x ray is for help.

 Keeping sharing about instruments and diagnosis method. Theme today is computer tomography of CT.

Computer tomography is a most informative modern methods for diagnosis,which allows to find a pathology on an early stages for development.And on these years she is very appreciated kind of testing,that CT  a right find a level for damage a lungs with coronavirus infection.

As first computer x ray tomography was tested on 1971 y and offered for the head scanning,and moneys for his manufacturing given a firm, which had a contact with group Beatles.And in 8 years America Physic and English engineer Haunsfild as for manufacturing computer tomography was taken A Nobel price.As in a base method a measurement and computer manufacturing a different of absorbing are x ray  with a different by a hardness tissues and organs, and within a following ten years apparatus  is perfect. As if first topographies manufactured a image of every fabric layer a few min, thus a modern multi spiral computer apparatus with a two x ray tubes within a sec are create a not stop time investigation and this is allow to short a time for investigation and low ray load on the patient.

And in difference  CT with other instrumental diagnosis kind,she is most informative in a testing for hollow organs and joints, than in use a magnet resonance tomography, but MRT better show are soft tissues are muscles, brain, vessels.

And from Xray test a CT differences a size three dimensional image with a forming a longitudinal and transverse  tissue layers, and source for x rays finding in a ring forming contour,and inside is table for patients. And doctor diagnostic will see on a screen for processes, as in lungs happening, head brain, heart, peritoneum, spine, joints, other organism systems is on the real time, And indications to the computer tomography are headaches, hypertension, dyspnoe, spine aches, joints, peritoneum, pelvis, anomalies theirs development, oncology risk, joints injures, soft tissues ,as CT doing for diagnosis put , especially if patient done before this a instrumental diagnosis or laboratory tests.And CT adding for a control a results of cure, as on surgery, as she is a need on emergency cases,when life a patient is in risk. And testing not adding for pregnancy, hard conditions, asthma bronchial, decompensated sugar diabetes, hard kidney and liver failure, allergy on the contrast substances, if theirs using in investigation, and in obesity,weight is very high,which a right need  for tomography.
