Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic detection and ultrasonic imaging, and in particular to a dual-mode transcranial ultrasonic Doppler imaging device. Background Art

[0002] Transcranial Doppler ultrasound imaging is a non-invasive method and the preferred method for intracranial vascular ultrasound detection. It has been widely used in clinical practice. Currently, transcranial Doppler ultrasound imaging is divided into two types: transcranial color Doppler (TCD) and transcranial color-coded duplex (TCCD).

[0003] While TCD can penetrate thinner areas of the skull and natural orifices to detect deeper intracranial vessels, it only provides Doppler imaging and cannot directly visualize intracranial vascular anatomy and blood flow. This limited observation leads to a certain rate of missed and misdiagnoses. Research reports indicate that TCD sensitivity for anterior circulation is 80%-90%, and for posterior circulation is approximately 80%, resulting in a limited success rate. While TCCD can simultaneously display two-dimensional structural and blood flow information, it currently relies heavily on the patient's bone window anatomy, making it difficult to accurately locate cranial sutures. It also suffers from poor penetration, low resolution, and difficulty accessing the bone window in some patients. Furthermore, the examination is time-consuming, presenting certain limitations in clinical application. Studies have shown that TCCD has a detection rate of approximately 75% for major intracranial vessels in elderly men and only one-third for elderly women. Therefore, current technical solutions and products for intracranial vascular detection suffer from varying degrees of deficiencies, and their success rate urgently needs to be improved.

[0004] Therefore, there is an urgent need for a dual-mode transcranial ultrasound Doppler imaging device. Summary of the Invention

[0005] The purpose of the present invention is to provide a dual-mode transcranial ultrasound Doppler imaging device to solve the problems in the above-mentioned prior art, which can effectively improve detection efficiency, shorten the inspection process, save time, and reduce detection costs.

[0006] The present invention provides a dual-mode transcranial ultrasound Doppler imaging device, comprising:

[0007] A primary screening probe, a detection probe, an operating handle and a cable. The primary screening probe and the detection probe are arranged at different positions of the operating handle and are respectively connected to the system host through the corresponding cables, so that the primary screening probe is connected to the primary screening working channel of the system host, and the detection probe is connected to the detection working channel of the system host. The primary screening probe is a TCD probe for TCD detection, and the detection probe is a TCCD probe for TCCD imaging detection.

[0008] As described above, in the dual-mode transcranial ultrasound Doppler imaging device, preferably, the number of array elements of the primary screening probe is 1-2, and the operating frequency range is 1-3 MHz.

[0009] In the dual-mode transcranial ultrasound Doppler imaging device as described above, preferably, the primary screening probe includes a single-element probe that uses pulsed Doppler for detection, or a dual-element probe that uses continuous Doppler for detection.

When the primary screening probe is a single-element probe that uses pulsed Doppler for detection, the cable connected to the primary screening probe is 1 coaxial cable; when the primary screening probe is a dual-element probe that uses continuous Doppler for detection, the cables connected to the primary screening probe are 2 coaxial cables.

[0011] In the dual-mode transcranial ultrasound Doppler imaging device as described above, preferably, the detection probe is a one-dimensional linear array probe, the number of array elements of the detection probe is 48-128, and the operating frequency range is 1-5 MHz.

[0012] In the dual-mode transcranial ultrasound Doppler imaging device as described above, preferably, the cables connected to the detection probe are multiple bundles, and the number of bundles of the cables connected to the detection probe is consistent with the number of array elements of the detection probe.

[0013] In the dual-mode transcranial ultrasound Doppler imaging device as described above, preferably, the primary screening probe is arranged on the side wall of the operating handle, and the detection probe is arranged at the front end of the operating handle.

[0014] As described above, in the dual-mode transcranial ultrasound Doppler imaging device, preferably, the primary screening probe and the detection probe are both arranged at the front end of the operating handle, and the primary screening probe and the detection probe are respectively located at the upper and lower parts of the front end of the operating handle.

[0015] In the dual-mode transcranial ultrasound Doppler imaging device as described above, preferably, the primary screening probe is arranged on a side wall of one end of the operating handle, and the detection probe is arranged on a side wall of the other end of the operating handle.

[0016] As described above, in the dual-mode transcranial ultrasound Doppler imaging device, preferably, the primary screening probe and / or the detection probe are made of piezoelectric ceramics, piezoelectric single crystals or piezoelectric composite materials, and an acoustic lens is provided on the surface of the primary screening probe and / or the detection probe.

[0017] The dual-mode transcranial ultrasound Doppler imaging device of the present invention uses a primary screening probe for rapid positioning and acquires rich detection image information, effectively improving detection efficiency and reducing detection time and cost. Simultaneously, it provides TCD and TCCD detection information, enriching the detection information. Compared with the previous method of using separate TCD and TCCD systems for detection, it can more effectively detect the same target location, and the corresponding detection information is more accurate and comprehensive.

It should also be understood that terms defined in, for example, general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0028] like Figure 1-Figure 3 As shown, the dual-mode transcranial ultrasound Doppler imaging device provided in this embodiment includes: a primary screening probe 1, a detection probe 2, an operating handle 3 and a cable 4. The primary screening probe 1 and the detection probe 2 are arranged at different positions of the operating handle 3, and are respectively connected to the system host through the corresponding cables 4, so that the primary screening probe 1 is connected to the primary screening working channel of the system host, and the detection probe 2 is connected to the detection working channel of the system host. The primary screening probe 1 is a TCD probe for performing TCD detection, and the detection probe 2 is a TCCD probe for performing TCCD imaging detection.

[0029] Among them, the number of array elements of the primary screening probe 1 is 1-2, and the operating frequency range is 1-3MHz. The primary screening probe 1 includes a single-element probe that uses pulse Doppler for detection, or a dual-element probe that uses continuous Doppler for detection. Specifically, the cable 4 connected to the primary screening probe 1 is 1-2 coaxial cables 4. When the primary screening probe 1 is a single-element probe that uses pulse Doppler for detection, the cable 4 connected to the primary screening probe 1 is 1 coaxial cable; when the primary screening probe 1 is a dual-element probe that uses continuous Doppler for detection, the cable 4 connected to the primary screening probe 1 is 2 coaxial cables. It should be noted that the present invention does not specifically limit the number of array elements and the corresponding operating frequencies contained in the primary screening probe 1 and the detection probe 2.

[0030] Furthermore, the detection probe 2 is a one-dimensional linear array probe having 48-128 array elements and an operating frequency range of 1-5 MHz. The cable 4 connected to the detection probe 2 is a multi-bundle cable, and the number of bundles of the cable 4 connected to the detection probe 2 is consistent with the number of array elements of the detection probe 2.

[0031] Furthermore, the primary screening probe 1 and / or the detection probe 2 are made of piezoelectric ceramics (PZT), piezoelectric single crystals (PMN-PT) or piezoelectric composite materials, and an acoustic lens is provided on the surface of the primary screening probe 1 and / or the detection probe 2 to seal and protect the primary screening probe 1 and the detection probe 2.

[0032] During operation, the primary screening probe 1 and the detection probe 2 are first connected to the system host. The primary screening mode is then selected on the system host. The system activates the primary screening working channel corresponding to primary screening probe 1 and disables the detection working channel corresponding to detection probe 2. The primary screening probe 1 is then positioned at the patient's cranial examination site by moving the operating handle 3. The probe is excited, echo signals are received, and Doppler detection is performed. The corresponding TCD results are displayed, allowing the inspector to determine the corresponding vascular location, depth, and flow velocity, and the corresponding test results are saved. Next, the detection mode is selected. The primary screening working channel corresponding to primary screening probe 1 is disconnected, and the multi-channel corresponding to detection probe 2 is activated. Based on the detection results of the primary screening probe, the imaging focus depth and range are set accordingly in the detection mode, and real-time TCCD detection is performed. The position and posture of detection probe 2 are fine-tuned by moving the operating handle 3 to achieve optimal imaging and detection results, and the corresponding results are saved. Finally, a comprehensive analysis is performed based on the primary screening and detection results.

[0033] Since the TCD probe used in the initial screening probe 1 has a lower frequency and can obtain more sensitive blood flow information compared to the TCCD probe, the initial screening probe 1 can be used to perform initial screening of patients, screening out people whose blood vessels cannot be detected due to anatomical limitations, and determining the people whose intracranial blood flow information can be detected by the detection probe 2. Then, the detection probe 2 using the TCCD probe can be used to perform two-dimensional grayscale imaging and color Doppler examination to display the two-dimensional structure and blood flow status of the intracranial and neck blood vessels. This saves time and, at the same time, performs TCCD examinations on the targeted population to improve its detection rate.

[0034] In some embodiments of the present invention, Figure 1 As shown, the primary screening probe 1 is arranged on the side wall of the operating handle 3 , and the detection probe 2 is arranged at the front end of the operating handle 3 .

[0035] In some embodiments of the present invention, Figure 2 As shown, the primary screening probe 1 and the detection probe 2 are both arranged at the front end of the operating handle 3, and the primary screening probe 1 and the detection probe 2 are respectively located at the upper and lower parts of the front end of the operating handle 3.

[0036] In some embodiments of the present invention, Figure 3 As shown, the primary screening probe 1 is arranged on one side wall of the operating handle 3, and the detection probe 2 is arranged on the other side wall of the operating handle 3. For example, the primary screening probe 1 is located on the top side wall of the operating handle 3, and the detection probe 2 is arranged on the bottom side wall of the operating handle 3. The combination of the detection probe 2 and the primary screening probe 1 in the present invention can be structured as follows: Figure 1 The combination of the front and side faces shown can also be Figure 2 The upper and lower ends shown, or Figure 3 It should be noted that the present invention does not specifically limit the positional relationship between the primary screening probe 1 and the detection probe 2.

[0037] The dual-mode transcranial ultrasound Doppler imaging device provided by the embodiments of the present invention uses a primary screening probe to quickly locate the patient and obtain rich detection image information, effectively improving detection efficiency and reducing detection time and cost. Simultaneously, it can provide TCD and TCCD detection information, enriching the detection information. Compared with the original use of separate TCD and TCCD systems for detection, it can more effectively detect the same target location, and the corresponding detection information is also more accurate and comprehensive.

To avoid obscuring the concept of the present disclosure, some details known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.
