Problems solved by technology

However, because the early signs and symptoms of the two types of stroke are similar, and thrombolytic therapy will cause the risk of further expansion of hematoma in patients with hemorrhagic stroke, it is difficult for doctors to make early and accurate judgments. The current rate of early thrombolysis in my country is very low. The status quo is extremely unfavorable to the reconstruction of neurological function in stroke patients

Embodiment 1

[0027] An array type infrared thermal imager, comprising an array type infrared receiver for receiving spontaneous infrared radiation from a human body; receptor (2), brow center receptor (3), right frontal receptor (4), right temporal receptor (5), the horizontal direction (x): the distance between the temporal receptor and the forehead receptor is 4.5cm, the forehead The distance between the receiver and the receiver between the eyebrows is 3.6cm; the vertical direction (y): the left frontal receiver (2) and the right frontal receiver (4) are 2cm higher than the receiver between the eyebrows (3), and the left temporal receiver (1) and the right The temporal receiver (5) is at the same height as the brow-center receiver (3). The five array elements of the infrared receiver are arranged in a ring shape, the diameter of the temperature measuring end of the receiver is 25cm, and the interval angle is 25°.

[0028] It also includes a photoelectric conversion system for convertin...

Embodiment 2

[0037] At 12:20 a.m. on March 20, 2015, the patient, female, 77 years old, was sent to Chongqing Southwest Hospital due to sudden right limb weakness for 2 hours. The muscle strength of the right limb was grade 0, lethargy, and the body temperature was 36.2 ℃. Using the infrared thermal imager described in Example 1, the patient's right temporal, right forehead, eyebrow center, left forehead, and left temporal were quickly measured at five points simultaneously, and the temperature measurement and recording process was completed at 12:25 p.m. see Figure 5 . It can be seen that the temperature of the left frontotemporal region is significantly higher than that of the right frontotemporal region, and the temperatures at five points are all higher than 36.5°C.

[0038] Then, at 12:55 p.m., the head CT examination was completed. The plain CT scan showed cerebral hemorrhage in the left basal ganglia area, pressure on the left lateral ventricle, and hemorrhage, and the bleeding v...

Abstract

The invention provides an array type infrared thermal imager. The array type infrared thermal imager comprises an array type infrared receiver, and the array type infrared receiver is used for receiving spontaneous infrared radiation of the human body and has five array elements including a left temporal receiver (1), a left forehead receiver (2), a glabellar receiver (3), a right forehead receiver (4) and a right temporal receiver (5); in the horizontal direction, the distances between the temporal receivers and the forehead receivers are 4.5 cm, and the distances between the forehead receivers and the glabellar receiver are 3.6 cm; and in the vertical direction, the left forehead receiver (2) and the right forehead receiver (4) are 2 cm higher than the glabellar receiver (3), and the left temporal receiver (1) and the right temporal receiver (5) are equal to the glabellar receiver (3) in height. The array type five-channel infrared thermal imager is provided, the array structure is in accordance with anatomical features of the head of the human body, and temperature measurement and imaging on the two sides of the head can be simultaneously carried out at a time; and under the condition that an imaging device does not exist, more time is won for treating a patient suffering from the ischemic stroke, and cranium temperature detection serves as the basis of differential diagnosis of the ischemic stroke and the hemorrhagic stroke for the first time.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to an array type infrared thermal imager and its application in the differential diagnosis of ischemic stroke and hemorrhagic stroke in the hyperacute stage. Background technique [0002] Cerebral apoplexy has a rapid onset, serious condition, and high death and disability rate, which greatly threatens the health of Chinese residents. Currently, there is no definitive treatment for hemorrhagic stroke (including cerebral hemorrhage and subarachnoid hemorrhage), and the only internationally recognized treatment for ischemic stroke is thrombolytic therapy within 3 hours of onset. However, because the early signs and symptoms of the two types of stroke are similar, and thrombolytic therapy will cause the risk of further expansion of hematoma in patients with hemorrhagic stroke, it is difficult for doctors to make early and accurate judgments. The current rate of early thrombolysis in my c...
