In order to improve the efficiency of imaging examination and better serve patients, the imaging department of Guzhen County People’s Hospital introduced artificial intelligence AI imaging diagnosis system to assist imaging doctors to provide faster and more accurate examination and diagnosis for the majority of patients.

Recently, the medical imaging department of Guzhen County People’s Hospital has introduced the world’s advanced artificial intelligence (AI) aided diagnosis system (pulmonary nodules, rib fractures, coronary arteries, head and neck vessels, stroke), which means that doctors have joined hands with "AI", and the medical imaging department has officially entered the era of intelligent medical care, providing more accurate, fast and efficient imaging diagnosis for the majority of patients, so that more patients can get timely diagnosis and treatment at an early stage.

AI artificial intelligence, leaving pulmonary nodules nowhere to hide

Early detection and treatment of lung cancer can greatly improve the quality of life and survival rate of patients. As the manifestation of early lung cancer, regular screening of pulmonary nodules is particularly important. Chest CT is the first choice for early screening of lung cancer. A chest CT examination will produce at least 400 CT images, which are great pressure and challenge to doctors’ eyesight, physical strength and endurance. However, naked eye screening is hard to avoid, especially for small pulmonary nodules close to blood vessels, which are prone to missed diagnosis. AI-aided diagnosis system for pulmonary nodules effectively solves this problem. It adopts advanced adaptive network technology and rule algorithm, and incorporates the deep learning and expert experience of a large number of selected cases. It can "carpet screen" every image scanned by chest CT in about 5 seconds, automatically mark suspicious parts, automatically detect the density, size and other related information of nodules, accurately locate the location of nodules and judge the types of nodules. It is highly sensitive and specific for the diagnosis of various pulmonary nodules, greatly improving the detection rate of tiny lesions, and generating a detection guide with one click.

AI artificial intelligence, automatic analysis of cerebral hemorrhage

AI artificial intelligence, sharp eyes detect small aneurysms

At present, the intelligent diagnosis of brain diseases includes cerebral hemorrhage, cerebral atherosclerosis, intracranial aneurysm and carotid vulnerable plaque evaluation. Intracerebral hemorrhage is a refractory disease with high mortality and disability rate in neurosurgery. AI+ head CT, based on machine vision and deep learning technology, bleeding volume, to determine whether there is cerebral hernia.

AI artificial intelligence, hidden fracture is no longer hidden.

AI can have a very high detection rate of rib fractures, especially occult fractures, based on chest CT data, and can accurately mark the accurate location and fracture type interpretation of rib fractures in patients with chest trauma.

AI artificial intelligence helps standardize the diagnosis and treatment of coronary heart disease

Artificial intelligence-assisted coronary CTA has high accuracy and sensitivity. It can automatically identify blood vessels, complete the identification of blood vessel segments, and at the same time, automatically complete the assessment of vascular stenosis and plaque properties, provide suggestions for plaque risk, improve the diagnostic efficiency, and promote the standardization of diagnosis and treatment of coronary heart disease.

At the same time, in order to actively integrate into the Yangtze River Delta integration and develop medical and health work with high quality, improve the professional quality of medical staff and facilitate residents’ medical treatment in Guzhen, Guzhen County People’s Hospital and Huashan Hospital affiliated to Fudan University in Shanghai set up Guzhen Sub-center of Chen Xingrong Imaging Consultation Center of Huashan Hospital affiliated to Fudan University, and carried out online and offline face-to-face consultation and remote consultation, opening a one-stop mode from medical treatment, examination, screening, diagnosis to treatment, so that smart medical treatment can enter ordinary people’s lives and empower medical efficiency. Let many patients relieve their troubles.

Work temperature is 30 ° C, and the amount of carrier flow under the long-term continuous 90% load is as follows:

1.5 square millimeters – 13A

2.5 square millimeters – 26A
4 square millimeters – 32A

6 square millimeters – 47A
16 square millimeters – 92A

25 square millimeters – 1220A

35 square millimeters – 150A

Current conversion power:

1A=220W,

10A=2200W,

So on and so forth.

For example, if the carrier traffic is 14A, it is: 220W × 14=3080W, then 1.5 square copper wire power is 3.08 kW.

Long-term current allowed by national standard:

4 square is 25-32A

6 square is 32-40A

In fact, these are the theoretical security values, and the limit value is more than these.

The maximum power allowed by the 2,5 square copper wires is: 5500W.

4 square 8000W, 6 square 9000W is no problem.

40A’s digital meter is normal 9000W absolutely no problem. The 12000W of the machine will not be burned.

03

Copper wire wires allow long-term current:

2.5 square millimeters (16A ~ 25A)
4 square millimeters (25A ~ 32A)
6 square millimeters (32A ~ 40A)

for example :

1. Each computer consumes approximately 200 ~ 300W (about 1 to 1.5a), then 10 computers need a 2.5-square millimeter copper wire power supply, otherwise a fire may occur.

2, the large 3 air conditioner consumption is approximately 3000W (about 14a), then one air conditioner requires a separate 2.5 square millimeter copper wire power supply.
3, the current housing outlet is generally 4 square millimeters of copper wire, so the home appliances open at the same time must not exceed 25A (ie 5500 watts), some people replace the wires in the house to 6 square millimeters copper wires are useless. Because the wires entering the meter are 4 square millimeters.
4. Early housing (15 years ago) The import line is generally 2.5 square millimeter aluminum wire, so the home appliances open at the same time must not exceed 13A (ie 2800 watts).

5, household appliances that are relatively large consumption are: air conditioner 5a (1.2), electric water heater 10a, microwave oven 4a, rice cooker 4a, dishwasher 8a, drying machine 10a with drying function, electric heater 4a.

Among the fire caused by the power supply, it is due to the heat of the hair, so all the joints must be welded, and the contact devices that cannot be welded 5 to 10 years must be replaced (such as socket, air switch, etc.).

Copper wire wire cable traffic standard cable flow oral estimation:

Take the next two o’clock in nine, and go to the next time.

Thirty-five take three o’clock, double bunom group is five.

The conditions have changed, and the high temperature is 10% off copper upgrade.

The number of tube is two or three four and eight seven six folds.

illustrate:

This mouth is not directly pointed out to various insulated lines (rubber and plastic insulation lines), but "cross-section is multiplied in a certain number" to be represented.

"Two five-point multiply by nine, go to the next time," said that various cross-sectional aluminum insulation lines of 2.5mm2 and below are about 9 times the number of carriers of the cross-section. Such as 2.5mm2 wires, the carrier flow is 2.5 × 9=22.5 (a). The multiple relationship between the carriage of 4mm2 and more wires and the number of cross-section is row, the line number is row, the multiple is successively reduced by 1, i.e., 4 × 8, 6 × 7, 10 × 6, 16 × 5, 25 × 4.

"Thirty-five Take Three Fiveth, Double Bunction] Say", it is said that 35mm2 lead traffic is 3.5 times the number of cross-section, ie 35 × 3.5=122.5 (a). Wire from 50 mm 2 and above, the multiple relationship between the amount of carrier flow and the number of cross-section becomes a set of two two lines, and the multiple is 0.5. That is, 50, 70mm2 wire has a total of 3 times the number of cross-section; 95, 120 mm2 lead traffic is 2.5 times the number of cross-sectional area, and push it according to the secondary.

"Conditions have changed, high temperature nine fold copper upgrades". The above mouth is the copper core insulation line, which is determined under the condition of 25 ° C in ambient temperature. If the aluminum core insulation line is in the area where the ambient temperature is higher than 25 ° C, the wire carrier flow can be calculated according to the above-mentioned oral calculation method, and then hits it again; when used is not an aluminum wire but the copper core insulation line, Its carrier flow is slightly larger than the same size aluminum wire, and can calculate a carrier flow than the aluminum wire in the above-mentioned oral method. For example, the flow of 25mm2 copper wire can be calculated according to 25 mm2 aluminum wire.
