The invention will be further explained by the description of the embodiments in conjunction with the drawings.
The present embodiment provides a method for displaying cerebral blood flow data, as shown in fig. 1 and 2, the method including:
s10, acquiring cerebral blood flow data of a preset time period of an acquisition point, wherein the preset data period is obtained according to an R-R interval determined by the electrocardiosignal.
Specifically, the R-R interval is a time interval between two adjacent R waves in the electrocardiosignal. The preset time period is an integral multiple of the R-R interval. For example, the preset time period is 3 times, 4 times, etc. the R-R interval. In addition, for different patients, the R-R intervals are different, so that the relation between the preset time period and the R-R intervals can be stored in advance, namely, the multiple value of integral multiple is stored in advance, when brain blood flow data are collected, electrocardiosignals are collected synchronously, the R-R intervals are determined according to the collected electrocardiosignals, and finally the duration of the preset time period is determined according to the multiple value of the R-R intervals and the preset time period.
Illustratively, in an implementation manner of this embodiment, the acquiring cerebral blood flow data of the acquisition point in the preset time period specifically includes:
s11, acquiring cerebral blood flow data and electrocardiosignals of a collection point;
and S12, recording cerebral blood flow data of a preset time period of the acquisition point when the electrocardio R wave signal is acquired.
Specifically, the electrocardiosignal and the cerebral blood flow data are acquired simultaneously, the cerebral blood flow data can be acquired through an ultrasonic probe, and the electrocardiosignal can be acquired through an electrocardio acquisition instrument. For example, the cerebral blood flow data is acquired by an automatic ultrasonic probe, and the electrocardiosignals are acquired by an electrocardio sensor. In addition, when a first acquisition point on a preset track is acquired through a probe, firstly, monitoring an R-R interval of an electrocardiosignal when the electrocardiosignal is acquired, and after the R-R interval is determined, determining a preset time period according to the R-R interval; secondly, an electrocardio R wave signal of the electrocardio signal is monitored, and when the electrocardio R wave signal is monitored, cerebral blood flow data of a preset time period of a collecting point is recorded, so that the cerebral blood flow data can be aligned with the electrocardio R wave signal, and cerebral blood flow data during heart beating can be presented when the cerebral blood flow data is dynamically displayed.
In addition, because the motion trail of the probe is provided with a plurality of acquisition points, after the cerebral blood flow data of the first acquisition point is acquired, the automatic probe moves to the next acquisition point according to the preset trail, and the next acquired cerebral blood flow data is acquired. In order to align the cerebral blood flow data of each acquisition point with the electrocardio signals, the electrocardio R wave signals can be monitored when the cerebral blood flow data of the next acquisition point is acquired, and the electrocardio R signals are used as the starting points for recording the cerebral blood flow data. Correspondingly, the acquiring of cerebral blood flow data of a preset time period of a collection point further comprises:
controlling the probe to move to the next acquisition point according to a preset track;
and when the electrocardio R wave signal of the electrocardio signal is monitored, acquiring cerebral blood flow data of a preset time period of the acquisition point.
Specifically, the acquisition point is a position point where cerebral blood flow data is adopted in the probe movement process, that is, the probe stops moving after moving to the acquisition point, an ultrasonic beam is adopted for the acquisition point, and cerebral blood flow information corresponding to the acquisition point is acquired by receiving return information of the ultrasonic beam. The acquisition point can be determined according to a preset track, wherein the preset track is a motion track of the automatic probe, can be in a shape like a Chinese character 'hui', can be in a snake shape and the like. Certainly, in practical application, when the cerebral blood flow data of the next point in the preset time period is collected, the current R-R interval of the electrocardiosignal at the current collecting time is obtained, and the preset time period is updated according to the current R-R interval. In addition, the collection points are associated with their corresponding R-R intervals, such that when brain blood flow data is dynamically displayed, a dynamic cycle period can be determined based on the correspondence of the collection points to their corresponding R-R intervals.
Further, in an implementation manner of this embodiment, for each acquisition point, when acquiring cerebral blood flow data of the acquisition point, the probe transmits a beam of ultrasound beam to an extension line direction of an ultrasound transmission direction with a probe surface as a starting point, the ultrasound beam may reach a preset depth of a human brain, and a plurality of depth intervals are formed between the probe and the preset depth, the plurality of depth intervals form a scanning depth sequence, and a group of longitudinal blood flow signals is formed along the ultrasound transmission direction according to the scanning depth sequence. In the embodiment, the depth interval is obtained by equally dividing the detection length from the probe face to the depth detectable by the transcranial ultrasound theory to obtain a scanning depth sequence, and the interval length of the depth interval is 1mm. Therefore, the cerebral blood flow data acquired by the ultrasonic probe is blood flow ultrasonic data on the scanning depth sequence, so that the cerebral blood flow data on each depth interval can be synchronously and dynamically displayed when the cerebral blood flow data is dynamically displayed.
By way of example: assuming that the maximum depth detectable by transcranial ultrasound theory is 154 mm and the effective minimum depth is 5mm, the detection length is 149mm, accordingly, the equal division results in 149 depth intervals, the depth of each depth interval is 1mm, and each depth interval is numbered according to the corresponding starting depth, namely, the 149 depth intervals are numbered 5-153 respectively. Therefore, the blood flow signals corresponding to each depth interval in each preset period of time can be numbered according to the number of the corresponding depth interval, and the ultrasonic signals of the blood flow on the depth sequence with the number of 5-153 are obtained.
And S20, dividing the acquired cerebral blood flow data into a plurality of cerebral blood flow data sections according to the R-R interval.
Specifically, the cerebral blood flow data is cerebral blood flow data of a preset time period, and the preset time period comprises at least one time of an R-R interval, so that the preset time period corresponding to the cerebral blood flow data can be divided into a plurality of sub-time periods according to the R-R interval, and the cerebral blood flow data corresponding to each sub-time period is determined according to the acquisition time corresponding to the cerebral blood flow data, so as to obtain a plurality of cerebral blood flow data segments. For example, the R-R interval is 1s, the preset time period is 4s, and the acquisition time period corresponding to the cerebral blood flow data is 11 hours, 30 minutes and 15 seconds to 11 hours, 30 minutes and 19 seconds, then the divided sub-time periods are 11 hours, 30 minutes and 15 seconds to 11 hours, 30 minutes and 16 seconds to 11 minutes and 30 seconds to 11 minutes and 17 seconds to 11 minutes and 30 seconds to 11 minutes and 18 seconds and 11 minutes and 30 seconds to 11 minutes and 19 seconds, respectively, so that cerebral blood flow data corresponding to each sub-time period can be determined, and the cerebral blood flow data can be divided into a plurality of cerebral blood flow data segments. That is, the cerebral blood flow data is divided into a plurality of cerebral blood flow data segments according to a time sequence, and the acquisition time length corresponding to each cerebral blood flow data segment is an R-R interval. Of course, it should be noted that, the dividing of the collected cerebral blood flow data into the plurality of cerebral blood flow data segments according to the R-R interval is to divide the cerebral blood flow data corresponding to each collection point after all the collection points on the preset trajectory are collected, so as to present the change of the cerebral blood flow during the heart beat.
And S30, circularly displaying the cerebral blood flow data segments on a pre-established cerebral blood flow model in sequence, and dynamically displaying the cerebral blood flow data in a preset time period through the cerebral blood flow model according to the electrocardio R-R interval.
Specifically, the cyclically displaying according to the time sequence means that the cerebral blood flow data segments are sequentially displayed according to the time sequence, and the display duration of each cerebral blood flow data segment is equal to the acquisition duration of the cerebral blood flow data. And after all the cerebral blood flow data segments corresponding to the acquisition points are displayed, displaying from the first cerebral blood flow data segment according to the time sequence until the acquisition points acquire the new cerebral blood flow data, replacing each cerebral blood flow data segment acquired by the acquisition points at the previous time by the cerebral blood flow data segments obtained by dividing the new cerebral blood flow data, and repeating until the acquisition of the cerebral blood flow data is finished.
Further, in this embodiment, the circularly displaying the cerebral blood flow data segments in sequence on a pre-established cerebral blood flow model, so as to dynamically display the cerebral blood flow data within a preset time period according to an electrocardiographic R-R cycle through the cerebral blood flow model specifically includes:
s31, dispersing the cerebral blood flow data segment to the corresponding R-R interval through Fourier transform aiming at each cerebral blood flow data segment to obtain the hemodynamic information of the cerebral blood flow data segment;
and S32, sequentially displaying the hemodynamic information corresponding to each cerebral blood flow data segment on the cerebral blood flow model according to a time sequence, and dynamically displaying the cerebral blood flow data in a preset time period through the cerebral blood flow model according to an electrocardio R-R cycle.
Specifically, the hemodynamic information includes one or more of a vascular elasticity index, a vascular resistance index, a vascular bandwidth index, a blood flow energy, a blood flow direction, and blood flow psychology information. Meanwhile, in dynamically displaying the hemodynamic information, the type of data to be displayed may be determined according to the priority of the data type of each data included in the hemodynamic information, and for example, when the priority of the blood flow velocity is highest, the blood flow velocity information may be displayed. In addition, the data type may also be determined according to a display model selected by the user, for example, the display mode is blood flow velocity, and blood flow velocity information is displayed. Certainly, in practical application, the data type is determined to have the highest priority by the display model selected by the user, so that the hemodynamic information of the cerebral blood flow data can be dynamically displayed according to the requirements of the user, and convenience is brought to the user.
Further, because the R-R intervals of the human body are not uniform, when the cerebral blood flow data segments are dispersed to the corresponding R-R intervals through Fourier transform, the display duration of each data segment on the time dimension can be the minimum effective R-R interval of the collected signals in each track point of the ultrasonic probe, and the part of the cerebral blood flow data of each track point of the ultrasonic probe, which exceeds the preset time period determined according to the minimum R-R interval, is discarded, and the cerebral blood flow data which does not meet the minimum R-R interval is complemented by using the tail end data of the data segment, so that the presented cerebral blood flow dynamics changes the graphical continuity on one hand, and on the other hand, the collected time corresponding to the discarded or supplemented data is short, and the presentation of the cerebral blood flow changes cannot be influenced.
Further, in order to judge the validity of the R-R interval, an R-R interval is preset, when the R-R interval is acquired, whether the R-R interval is in the R-R interval is judged, when the R-R interval is in the R-R interval, the R-R interval is judged to be a valid R-R interval, and when the R-R interval is not in the R-R interval, the R-R interval is judged to be an invalid R-R interval. Further, the minimum valid R-R interval may be the minimum R-R interval of all valid R-R intervals determined according to a preset R-R interval or may be an average of all valid R-R intervals. In an embodiment, the minimum effective R-R interval is preferably an average of all effective R-R intervals.
Further, in an implementation manner of this embodiment, sequentially displaying, according to a time sequence, the hemodynamic information corresponding to each segment of the cerebral blood flow data segment on the cerebral blood flow model, so as to dynamically display the cerebral blood flow data within a preset time period according to the electrocardiographic R-R cycle through the cerebral blood flow model specifically includes:
s321, acquiring a display color corresponding to the hemodynamic information in a preset hemodynamic information database aiming at each cerebral blood flow data segment;
and S322, sequentially displaying the display colors corresponding to the cerebral blood flow data segments on the cerebral blood flow model according to a time sequence, so that the cerebral blood flow model dynamically displays the display colors within a preset time period.
Specifically, the display color of the cerebral blood flow model in the dynamic display preset time period refers to that the hemodynamic information of the cerebral blood flow data which changes with the heart pulsation is dynamically displayed through the display color in each depth interval in the cerebral blood flow model. The correspondence relationship between the cerebral blood flow data and the display color may be preset, wherein the display color may include black, red, blue, green, and the like. Meanwhile, the display colors corresponding to the data included in the hemodynamic information may be different, and different numerical values of the data correspond to the different display colors, so that the change condition of the data can be quickly determined according to the display colors.
For example, 1, the correspondence between the blood flow velocity and the display color may be: the absence of a regular pulsatile blood flow signal is indicated by the use of black (0-1 cm/sec) in the velocity range where the peak blood flow velocity is 0-750 cm/sec; slow to fast blood flow velocity towards the probe is indicated using a linear gradient of dark red (1 cm/sec) to light red (750 cm/sec); a linear gradient of dark blue (1 cm per second) to light blue (750 cm/second) is used to indicate slow to fast blood flow velocity away from the probe.
Example 2, correspondence between blood flow energy information and display color: normalizing the blood flow energy intensity to a value range interval of 0-100, wherein the value range interval represents the blood flow energy from weak to strong, and correspondingly, a linear gradual change color from deep red (representing 0) to light red (representing 100) is used for representing the change condition of the blood flow energy.
