Embodiment 1

[0029] figure 1 It is a schematic flowchart of a breathing guidance method in Embodiment 1 of the present invention. This embodiment is applicable to the situation where the brightness change of the breathing guide color is used to guide the breathing of the target object, and the method is executed by a breathing guiding device, which is realized by software and / or hardware, and is specifically configured in medical imaging equipment middle. Among them, the medical imaging equipment needs to perform breathing guidance when shooting images.

[0030] Such as figure 1 One method of breathing guidance is shown, including:

[0031] S110. Obtain an initial hue value and an initial saturation value of the breathing guide color, and a current brightness value in a preset target brightness adjustment model.

[0032] Wherein, the breathing guide color is used to instruct the target object to adjust breathing according to the target brightness.

[0033] When performing breathing gu...

Embodiment 2

[0046] Figure 2A It is a schematic flowchart of a breathing guidance method in Embodiment 2 of the present invention. In this embodiment, additional optimization is performed on the basis of the technical solutions of the foregoing embodiments.

[0047] Further, before "obtain the initial hue value and initial saturation value of the breathing guide color, and the current brightness value in the preset target brightness adjustment model", add "determine the standard sinusoidal curve according to the unit time and unit amplitude, as A target breathing intensity curve; sampling the target breathing intensity curve according to the set frequency to obtain an initial brightness adjustment model; adjusting each intensity value of the initial brightness adjustment model according to a preset brightness peak value to obtain the target brightness adjustment model ", so as to form a determined target brightness adjustment model before obtaining the current brightness value in the prese...

Embodiment 3

[0066] Figure 2C It is a schematic flowchart of a breathing guidance method in Embodiment 3 of the present invention. In this embodiment, on the basis of the technical solution provided in the second embodiment, only S211A-S213A are replaced with S211B-S215B, so as to enrich the determination method of the target brightness adjustment model and improve the determination mechanism of the target brightness adjustment model.

[0067] Such as Figure 2C One method of breathing guidance is shown, including:

[0068] S211B. Within the set sampling period, acquire the breathing intensity values ​​of the measured object according to the set sampling frequency, and fit each breathing intensity value to obtain an initial breathing intensity curve.

[0069] Wherein, the method of obtaining the breathing intensity value of the measured object may be: fixing the airbag on the abdomen of the measured object with a bandage, performing multiple breathing tests, and determining the breathin...

Abstract

The embodiment of the invention discloses a breathing guiding method and device, a medical imaging device and a storage medium. The method includes the steps of obtaining an initial hue value and an initial saturation value of a breath guiding color, presetting a current brightness value in a target brightness adjustment model; determining the primary color components of a red light group, a greenlight group, and a blue light group contained in a breathing guiding color according to the initial color value, the initial saturation value, and the current brightness value; determining the lightsource intensity of the red light group, the green light group, and the blue light group according to each primary color component, and controlling the target brightness of the breathing guide color displayed according to the intensity of each light source; wherein the breathing guiding color is used to indicate a target object to adjust the breathing according to the target brightness. By adopting the above scheme, the current brightness value in the target brightness adjustment model is introduced, and the brightness of the breath guiding color is adjusted based on the current brightness value, thereby instructing the target object to adjust the breathing according to the target brightness of the breathing guide color.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical equipment, and in particular, to a breathing guidance method and device, medical imaging equipment, and a storage medium. Background technique [0002] When medical imaging equipment is used to scan special parts such as the patient's abdomen, it usually requires the patient to hold his or her breath several times. However, due to the disordered respiratory rhythm, poor breath-holding or different breath-holding depths of the patient, the image will be blurred, misaligned, or motion artifacts will be generated, which will directly affect the imaging quality and cause unnecessary radiation damage to the patient. [0003] In the prior art, the patient's breathing is usually guided by controlling the brightness of the surrounding light environment of the imaging device. However, when the brightness change control is performed, the color of the light environment is accompanied b...
