DETECTION MODE CONTROL SWITCH

Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of medical detection device and, in particular, to a detection mode control circuit.BACKGROUND

[0002] Progression of various chronic liver diseases such as viral hepatitis (hepatitis A, hepatitis B, hepatitis C, etc.) will be accompanied by liver fibrosis, and a process of the liver fibrosis will be accompanied by an increase of liver elasticity. Therefore, liver elasticity information is a parameter that can be used to diagnose a degree of fibrosis of liver tissue. Transient elastography technology is a technology for quantitatively detecting elastic modulus of tissues, and this technology transmits low-frequency shear waves to a liver through a body surface, tracks propagation of the shear waves in tissues, and then can accurately and quantitatively calculate the elastic modulus of the tissues. A detection process of the elastic modulus of the tissues is referred to as E-ultrasonic detection for short.

[0003] At present, a better solution is to carry out histomorphological detection, such as B-mode ultrasonography, computed tomography (CT), etc., so as to accurately locate an area to be detected and eliminate interference of ribs, connective tissues, blood vessels, etc., thereby improving accuracy of the E-ultrasonic detection.

[0004] However, there is a disadvantage in the above solution. When appropriate diagnosis positions and angles are selected through morphological detection, an E-ultrasonic probe needs to be replaced. Since it cannot be guaranteed that positions corresponding to probes before and after replacement are completely consistent in a process of replacing the probe, and offset of a detection position will lead to deviation of diagnostic data, the accuracy of the E-ultrasonic detection is then affected.

[0005] US 2016 / 143621 A1 discloses an ultrasound elastography system (10) for providing an elastography measurement result of an anatomical site (32) a corresponding method. The system (10) is configured to visualize a suitability for shear wave elastography of the region of interest (33) to the user within the ultrasound image (52) and / or to recommend an elastography acquisition plane (48, 50) for conducting shear wave elastography to the user. By this, proper selection of a location for an elastography measurement may be supported.

[0006] US 2016 / 030003 A1 discloses an ultrasonic diagnostic device, including a display module, an imaging system and multiple probes. The multiple probes are capable of being attached to different positions on a body surface of a patient, such that synchronous and real-time scanning can be performed by the multiple probes for body parts corresponding to those different positions on the patient's body surface. Echo signals can be obtained by the multiple probes through scanning, and may then be transmitted to the imaging system. The imaging system can convert the multiple echo signals transmitted from the multiple probes into multiple ultrasonic images. The display module may be coupled to the imaging system. It can receive the multiple ultrasonic images processed and outputted by the imaging system, and display these images synchronously.SUMMARY

[0026] In one of embodiments, the morphological detection module 100 includes a first interface 110 and a second interface 120, where the morphological detection module 100 is connected to the switch module 300 through the first interface 110, and the morphological detection module 100 is connected to a morphological detection probe 500 through the second interface 120; the morphological detection module 100 is configured to generate a morphological detection control signal and a first control signal according to the user instruction or the system setting; the first control signal controls the first interface 110 and the second interface 120 to turn on or off, and transmits the morphological detection control signal to the switch module 300 through the first interface 110 or transmits the morphological detection control signal to the morphological detection probe 500 through the second interface 120 to perform morphological detection.

[0027] Specifically, when a user needs to use the morphological detection probe 500 to perform morphological detection, the morphological detection module 100 generates the morphological detection control signal and the first control signal according to the user instructions or the system setting. Where the user instruction may be a control instruction received from the user via an upper computer, or a control instruction sent from a network side, etc. The system setting may be a control instruction stored in advance for the system. The morphological detection includes: B-mode ultrasonography, A-mode ultrasonography, M-mode ultrasonography, CT, and MRI, etc. Preferably, the morphological detection may be a B-mode ultrasonography detection; and the morphological detection probe may be a B-mode ultrasonography probe. The first control signal includes: an on or off signal of the first interface 110 and an on or off signal of the second interface 120. When the morphological detection probe is used, the first control signal controls the first interface 110 to turn off and the second interface 120 to turn on, i.e., the morphological detection module 100 transmits the morphological detection control signal to the morphological detection probe 500 through the second interface 120 to perform morphological detection. After detecting and obtaining a morphological detection echo signal, the morphological detection probe 500 transmits the morphological detection echo signal to the morphological detection module 100 through the second interface 120 for processing. When the user needs to use the compound probe 600 to position with morphological detection first and then perform elasticity detection on a determined position, the morphological detection module 100 receives input information from the user and generates the morphological detection control signal and the first control signal according to the input information from the user. The first control signal controls the first interface 110 to turn on and the second interface 120 to turn off, i.e., the morphological detection module 100 transmits the morphological detection control signal to the switch module 300 through the first interface 110. The elasticity detection module 200 receives input information from the user, generates the elasticity detection control signal, a motor drive signal, and the second control signal according to the input information from the user, and transmits the elasticity detection control signal, the motor drive signal, and the second control signal to the switch module 300.

When a morphological detection position is needed, the second control signal controls the switch module 300 to enable the morphological detection module 100 to conduct with the compound probe 600, i.e., the morphological detection control signal is transmitted to the compound probe 600 to perform morphological detection. After the compound probe 600 performs the morphological detection to obtain a morphological detection echo signal, the morphological detection echo signal is transmitted to the morphological detection module 100 through the first interface 110 for processing. When morphological detection is needed, the second control signal controls the switch module 300 to enable the elasticity detection module 200 to conduct with the compound probe 600, i.e., to transmit the elasticity detection control signal and the motor drive signal to the compound probe 600 to drive the motor to vibrate to generate and emit low-frequency shear waves, to generate and emit ultrasonic waves to track the low-frequency shear waves, so as to perform elasticity detection, and then to transmit the elasticity detection echo signal to the elasticity detection module 200 for processing after the compound probe 600 performs the elasticity detection to obtain the elasticity detection echo signal.

[0030] Specifically, the morphological detection module 100 is further configured to generate a third control signal according to the user instruction or the system setting, and transmit the third control signal to the extended module 400; and the extended module 400 controls the plurality of output interfaces to turn on or off according to the third control signal. When the user needs to use the morphological detection probe 500 to perform morphological detection, the morphological detection module 100 transmits the morphological detection control signal to the extended module 400 through the second interface 120, and the extended module 400 controls each output interface to turn on or off according to the third control signal. The morphological detection control signal is transmitted to the morphological detection probe 500 corresponding to an on output interface through the on output interface to perform the morphological detection.

Where the extended module 400 may be an apparatus such as a hub that can divide one signal into a plurality of identical signals.

The switch module selectively transmits the morphological detection control signal or the elasticity detection control signal to a compound probe according to control of the second control signal, and controls the compound probe to perform morphological detection or elasticity detection. Through the detection mode control circuit, the embodiment of the present invention controls the compound probe to perform morphological detection and elasticity detection, and use of the compound probe for detection enables an elasticity detection position to be more accurate, and further enables diagnosis data to be more accurate.
