It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, the present application provides a method for acquiring an image, which includes the following steps:
step S101, obtaining the change frequency of the light and shade change of the light;

Step S102, controlling the light and shade change of the light according to the change frequency, wherein the light and shade change of the light is used for guiding the measured object to adjust the initial breathing state, so that the breathing state of the measured object corresponds to the light and shade change of the light;
after the preset frequency value of the light is obtained, the light and shade change of the light keeps a fixed and unchangeable frequency, so that the measured object changes along with the light and shade change of the light, and the breathing of the measured object is gradually adjusted.
Step S103, when the breathing state of the measured object corresponds to the light and shade change of the lamplight, collecting the image information of the measured object;
the breathing state of the tested object is gradually close to the lighting state by the light and shade change of the lighting, and when the breathing state of the tested object corresponds to the light and shade change of the lighting, the image information of the tested object is collected by the collecting equipment.
Optionally, the breathing state of the measured object corresponds to the light and shade change of the light, and the breathing frequency value may be in a preset range when the breathing frequency is kept consistent. The image information of the acquisition object may be X-ray image information, B-mode ultrasound image information, Computed Tomography (CT) image information, Magnetic Resonance (MR) image information, or the like. In one embodiment, the preset range of respiratory frequency values may be divided into three categories: adults, elderly people and children, each type of population sets a different preset breathing frequency value. For example, the value of the breathing frequency of an adult may be set to any value between 16-20 according to clinical experience.
Optionally, the respiratory state of the measured object corresponds to the light and shade change, the respiratory frequency value of the measured object may be equal to the light and shade change frequency value of the light, the respiratory frequency value of the measured object may fall within the interval range of the light and shade change frequency, or the respiratory frequency value of the measured object may be a value corresponding to a percentage of the light and shade change frequency value of the light.
According to the method for acquiring the image, the change frequency of the light and shade change of the light is acquired, the light and shade change of the light is controlled according to the change frequency, and the light and shade change of the light is used for guiding the measured object to adjust the initial breathing state. When the breathing state corresponds to the light change state, a high-quality image picture can be acquired. According to the method, the tested object is guided to breathe calmly by setting the light and shade alternating change of the light, so that the tension of the tested object is relieved, the motion artifacts of all parts of the image of the tested object are reduced, the quality of the collected image is greatly improved, and the user experience is improved.
In one embodiment, the change frequency of the light and shade change of the lamp light is regulated and controlled according to a preset breathing cycle, and the change frequency of the light and shade change of the lamp light corresponds to the preset breathing cycle.
The change frequency of the light and shade change of the light is regulated and controlled according to the breathing cycle preset by related personnel, and the light can be defined as a breathing cycle from the darkest to the brightest; the lamp light can be defined as a period from darkest to brightest and then brightest to darkest, and the change frequency of the light and shade change of the lamp light can be regulated and controlled according to the setting of the breathing period by related personnel. For example, in one period of light brightness change, the light brightness is changed from dark to light (gradually increased) to correspond to the inspiration state of the respiration period; the light is turned from bright to dark (gradually reduced) to correspond to the expiratory state of the breathing cycle.
Further, in one embodiment, the step of obtaining the frequency of the change of the brightness change of the lamp light comprises:
step S201, acquiring an initial respiration state of a measured object;
the initial breathing state is the number of breaths per minute of the subject before the breathing state is adjusted.
Optionally, a pulse monitoring device is arranged on the finger of the measured object, and the pulse times per minute of the measured object are obtained through the pulse monitoring device. Since normally the ratio of respiration to pulse is 1: 4, pulse monitoring facilities can include the pulse inductor, and this pulse inductor can supply that the finger indicates that the abdomen is down to correspond to contact in this pulse inductor upper end to survey the frequency of pulse beat, through this proportional relation and measurand per minute's pulse number of times can obtain measurand per minute's breathing number of times. The pulse monitoring device may also monitor changes between heart rate variability data and respiration, thereby helping to find the most appropriate respiratory rate for the individual.
Alternatively, the heart rate, i.e. the number of pulses per minute, is normally low, but sometimes a weak heart beat results in an undetected pulse, which makes the detected heart rate larger than the pulse rate. The respiration monitoring device detects the initial respiration state of the tested object, and the respiration state can also comprise a lot of information, such as: and carrying out corresponding treatment on the measured object according to the acquired relevant information, such as the respiratory frequency, the oxygen uptake amount each time, the air displacement each time and the like. The respiration monitoring apparatus of the present embodiment may be designed as any one of the well-known types of respiration monitoring devices, such as a respiration belt type (which includes a respiration sensor and is typically attached to the chest of a subject of interest), a respiration bellows type, or one of the various known spirometer types. In this embodiment, the breathing monitoring device is configured to: a breathing bag air bag is bound on the abdomen of the tested object by a binding band, and the breathing of the tested object causes the abdomen to rise and fall, so that the air bag is pressed to deform; by detecting the air pressure change in the air bag, the respiration signal waveform is output and the information such as the respiration frequency is obtained through calculation.
Alternatively, the respiration monitoring device can also be designed as an optical camera with its lens directed at the chest of the measured object or as a device capable of acquiring a scanned scout image. For example, in one embodiment, the respiration monitoring device may acquire a plurality of positioning images of the measured object or the contour of the measured object in at least one period in advance through an optical camera or other scanning equipment during the imaging scan; then, obtaining the central coordinates of the one or more time point positioning images or the outline of the measured object; the center coordinates of the positioning image or the outline of the measured object corresponding to a plurality of time points can determine the breathing curve of the measured object. For example, the midline point of the object to be measured corresponds to the position of the upper edge of the diaphragm or the liver, and when the object to be measured is in an inspiration state, the central coordinate is the maximum value; when the tested object is in an expiratory state, the central coordinate is the minimum value; the breathing frequency during a cycle can be determined by the peak, peak-to-trough, and plateau on the breathing curve (peak-to-end inspiration, peak-to-trough to end expiration, and plateau to breath hold).
In a further embodiment, the coordinates of the center of the scout image or the contour of the measured object corresponding to a plurality of time points can determine the breathing curve of the measured object by: acquiring a positioning image or a contour of a measured object at regular time intervals, and acquiring center coordinates of the positioning images or the contour of the measured object at a plurality of time points; and fitting a plurality of central coordinates to obtain a respiratory motion curve.
Alternatively, the respiration monitoring device can also be designed as an optical camera with its lens directed at the chest of the measured object or as a device capable of acquiring a scanned scout image. For example, in one embodiment, the respiration monitoring device may acquire a plurality of positioning images of the measured object or the contour of the measured object in one period in advance through an optical camera or other scanning equipment, divide one period into different phase phases, and classify the positioning images or the contour of the measured object belonging to the same phase into one group; and then, acquiring the central coordinates of the positioning image or the contour of the measured object of each group, and establishing a corresponding relation between the respiratory motion of the measured object and the central coordinates of the positioning image or the contour of the measured object, thereby establishing a respiratory motion model. The imaging system can be provided with a positioning image acquisition device, and in the imaging scanning process, the positioning image acquisition device is utilized to acquire a positioning image of a measured object; the center coordinates of the positioning image can be obtained through the positioning image acquired by imaging; furthermore, the phase of the respiratory motion of the measured object at each moment can be determined by using the central coordinate of the positioning image and the respiratory motion model in the imaging acquisition process, so that the respiratory state of the measured object is obtained. Alternatively, the number of identical phases per unit time may correspond to the frequency value of the breathing movement. Step S202, acquiring the change frequency of the light and shade change of the light according to the initial breathing state, and controlling the light and shade change of the light, wherein the light and shade change of the light is used for guiding the measured object to adjust the initial breathing state;
after receiving the initial breathing state of the tested object, the breathing disorder or the rush of the tested object can be caused due to the stress and the like, the light and shade frequency value is preset according to the breathing condition of the tested object, the tested object is guided to breathe, the light and shade frequency value is gradually changed and can be gradually accelerated or gradually slowed down, and the tested object is guided to adjust the breathing through the rhythm conversion, so that the breathing state of the tested object is gradually kept consistent with the light change state.
Optionally, the light and shade change of the light may be a set fixed time length, and the time length is exceeded to change, or may be changed according to the breathing change of the measured object. The frequency of the light change can be changed from fast to slow or from slow to fast.
Alternatively, the present embodiment provides a brain wave sensor that analyzes the degree of mental stress of the autonomic nervous system from the initial respiratory state; detecting brain waves of the brain of the user through a brain wave sensor, and analyzing the mental stress degree of the central nervous system from the brain waves; calculating the mental stress score of the user according to the mental stress degree of the autonomic nervous system and the mental stress degree of the central nervous system; when the psychological pressure score of the user exceeds the score value of the normal psychological pressure of the human body, the user is guided to carry out regular breathing training by controlling the light and dark frequency of the light so as to relieve the psychological pressure by self. At this time, the optimal bright and dark frequency of the control light corresponds to the score value of the normal psychological pressure of the human body.
And step S203, when the breathing state of the measured object corresponds to the light and shade change of the lamp light, acquiring the image information of the measured object.

For example: the ambient background light is softer and light yellow, and the color of the light can be selected from the light of a blue substrate.
