Medical is video technology

stroke, and then medical school interview advice part 1

Medical becomes the evolution that obtained advance rapidly a few years in the past like the technology, nowadays, these new technologies can discriminate human body any structures and courses of a lot of important live thing, for instance different hematic velocity of flow is spent. This group of pictures announced not only under the human body after sicken is tectonic, still give a person on the vision in order to pound.

1. Schizoid cerebra image

Tensor of schizoid cerebra dispersion is become picture (DTI)

A kind of new method that describes cerebrum structure is called dispersion tensor is become picture (DTI) . This piece of graph is medical treatment personnel when studying a schizoid, use dispersion tensor to become what make like the technology.

　　

Become like such dispersion tensor like the graph (present means and the image previously to differ) can announce how does brain tumor affect nerve cell join, guide medical treatment personnel to have brain operation.

Dispersion tensor is become resembling is nuclear magnetic resonance is become actually picture (the special form of MRI) . E.g. , if say nuclear magnetic resonance is become,resembling is the hydrogenous atom in tracking water element, so dispersion tensor is become resembling is cartography of direction of shift of basis water element. Nerve cell fiber is long and thin, the element can diffuse along nerve cell fiber normally. Researcher can highlight the place that water element and fiber of cell of nerve of a group of groups run with same way. Become like such dispersion tensor like the graph (present means and the image previously to differ) can announce how does brain tumor affect nerve cell join, guide medical treatment personnel to have brain operation. It still can announce with the apoplectic, much sclerosis that send a gender, schizophrenia, slight erratic change that reads an obstacle to concern.

2. Nuclear magnetic resonance is become picture

Nuclear magnetic resonance is become picture

Become in nuclear magnetic resonance fall like the instrument, the patient lies in cylindrical inside magnetic body, expose Yu Jiang‘s big magnetic field. Once expose,be in magnetic field, the proton of water element is met line, if suffer the attack of radio wave, they can make posse in disorder instantly, won‘t do linear. Arrange a process afresh in proton in, computer can collect their signal, process image. The organization that contains a lot ofwater can issue stronger signal, look in generated image brighter, and skeletal and opposite darker. This technology uses herein will describe cerebrum and cervical artery. After injecting to be used at be being become comparatively to resemble a dose, radiation expert repeats scanning, at this moment, into mobile in blood-vessel like the agent, make they can see well cause apoplectic, head aneurism and all sorts of jam traumaticly content.

Vertebral canal and the bright area that cerebrum manages express fluid of cerebral spinal cord.

Nuclear magnetic resonance is become often still use in nerve to become like the technology like the respect. Vertebral canal and the bright area that cerebrum manages express fluid of cerebral spinal cord; Be down outspread the strip state system to the body is spinal cord.

3.X smooth blood-vessel is become like art

X smooth blood-vessel is become like art

X smooth blood-vessel is become let the so petty blood-vessel on the hand appear like art come out. The picture quality that by this kind newest number flaw-detecting apparatus generates can let radiative family doctor need not use thing of high dose radiate, also can see well fine point of the organ. The immediate effect that this piece of photograph showed the hand is traumatic -- flow to the 4th finger without blood, and the little blood vessel of other finger is clear however and visible.

X smooth blood-vessel is become like art

Make useful medical image involve two main measure: It is collect data, 2 it is these data changeover is but fast, accurate unscrambled image. This piece of image calls X ray fault to become by a kind picture (the advanced X optical technology of abbreviation CT) is generated, highlighted the progress of two afore-mentioned respects. Body scale software (blood-vessel of Volume-renderingsoftware) union CT is become like the technology, can identify a heart around aorta (from image top outspread to the big pink blood-vessel all round body bottom, heart) unusual situation. Again downward, OK and clear see liver (purple) with the kidney (vermeil) . Accurate determine aorta diameter is crucial, whether to because the surgeon can lend this judgement aorta,put in cracked risk.

4.CT blood-vessel is become picture

CT blood-vessel is become picture

The CT blood-vessel that shows the pelvis to here in order to is become picture for, into meeting resembling a dose inject arrives vein, make blood-vessel forms bright contrast with parenchyma. Computer software can highlight the difference between skeleton and blood-vessel further, make a doctor OK make clearer, more apace is diagnosed.

Two hands in this graph are the result that cadaver check scans

Normally the circumstance falls, CT uses light source of a X, but researcher can differ two the X illuminant union of energy rises, present parenchyma more clearly. Basis spy methodize (the tendon of two hands in pursueing for instance and ligament) the fact that absorbs different energy, the instrument can highlight the picture that shows them. To examine this kind presents the accuracy of means, researcher undertook scanning to the body, be the same as scanning result their " fictitious " discovery is compared. Two hands in this graph are the result that cadaver check scans. Of course, the main goal of CT technology is to improve health, but also put in the possibility that is used at fictitious cadaver check. Regard legal medical expert as the one part of the examination, like such CT scanning can announce the method of the object such as the penknife.

5. Positron radiates a scanning art (PET)

Positron radiates a scanning art (PET)

A lot of medical are anatomizing tectonic respect into main like the technology concentration, positron radiates a scanning art (PET) differs somewhat: The image that this kind of technology creates highlighted cellular activity. The doctor gives a patient inject radioactivity tracer first, then, absorb the cell with most tracer to be able to give out light. The tracer in this graph is dextrose. Cancer cell can grow quickly and break up, because this meeting wastes a large number of energy, absorb dextrose. Liver of patient of red colour specification and humeral ministry have a problem. Cerebrum and heart (C form is red piece it is heart muscle wall, namely cardiac muscle layer) same meeting wastes energy in great quantities, also can appear so come out. PET scanning and CT scanning both are united in wedlock, the human body in can stressing a plan is tectonic. The graph is PET scanning, graph 2 it is CT scanning, graph the 3 union that are PET scanning and CT scanning, this makes a doctor OK see well well and truly problem place. Become with nuclear magnetic resonance like appearance, radiative layer scanner can collect positron the data of many plane. Pursue medium in these 3 pieces, have only respectively " section " show come, should be united in wedlock only all these section, can make three-dimensional plan.

Pursue medium in this piece, the cancerous organization that PET scanning affirms is object of shape of sky blue wad, and CT scanning lock decided its position in colon.

According to CT scanning, kidney (gules) , skeleton and hemal structure are clear also visible. PET technology is the most commonly used check at oncology, also apply at cardiology and neurology domain. The instrument manufacturer that makes this plan " GEHealthcare " introduced two kinds of systems a few days ago, help researcher explores new clinical application. The Bruce · Hillman that occupies American radiology institute (Introduction BruceHillman) , because can monitor cellular function, PET is human body of a series of monitoring of in order to cell and inferior the typical delegate of cellular new tool
