Abstract
Ultrasound (US) has gained popularity as a guidance modality for percutaneous needle insertions because it is widely available and non-ionizing. However, coordinating scanning and needle insertion still requires significant experience. Current assistance solutions utilize optical or electromagnetic tracking (EMT) technology directly integrated into the US device or probe. This results in specialized devices or introduces additional hardware, limiting the ergonomics of both the scanning and insertion process. We developed the first ultrasound (US) navigation solution designed to be used as a non-permanent accessory for existing US devices while maintaining the ergonomics during the scanning process. A miniaturized EMT source is reversibly attached to the US probe, temporarily creating a combined modality that provides real-time anatomical imaging and instrument tracking at the same time. Studies performed with 11 clinical operators show that the proposed navigation solution can guide needle insertions with a targeting accuracy of about 5 mm, which is comparable to existing approaches and unaffected by repeated attachment and detachment of the miniaturized tracking solution. The assistance proved particularly helpful for non-expert users and needle insertions performed outside of the US plane. The small size and reversible attachability of the proposed navigation solution promises streamlined integration into the clinical workflow and widespread access to US navigated punctures.

[PMID: 38636327 DOI: 10.1016/j.compbiomed.2024.108453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 03/11/2024] [Accepted: 04/07/2024] [Indexed: 04/20/2024]
Abstract
PURPOSE Biopsies play a crucial role in determining the classification and staging of tumors. Ultrasound is frequently used in this procedure to provide real-time anatomical information. Using augmented reality (AR), surgeons can visualize ultrasound data and spatial navigation information seamlessly integrated with real tissues. This innovation facilitates faster and more precise biopsy operations. METHODS We have developed an augmented reality biopsy navigation system characterized by low display latency and high accuracy. Ultrasound data is initially read by an image capture card and streamed to Unity via net communication. In Unity, navigation information is rendered and transmitted to the HoloLens 2 device using holographic remoting. Concurrently, a retro-reflective tool tracking method is implemented on the HoloLens 2, enabling the simultaneous tracking of the ultrasound probe and biopsy needle. Distinct navigation information is provided during in-plane and out-of-plane punctuation. To evaluate the effectiveness of our system, we conducted a study involving ten participants, assessing puncture accuracy and biopsy time in comparison to traditional methods. RESULTS Ultrasound image was streamed from the ultrasound device to augmented reality headset with 122.49±11.61ms latency, while only 16.22±11.25ms was taken after data acquisition from image capture card. Navigation accuracy reached 1.23±0.68mm in the image plane and 0.95±0.70mm outside the image plane, within a depth range of 200 millimeters. Remarkably, the utilization of our system led to 98% and 95% success rate in out-of-plane and in-plane biopsy, among ten participants with little ultrasound experience. CONCLUSION To sum up, this paper introduces an AR-based ultrasound biopsy navigation system characterized by high navigation accuracy and minimal latency. The system provides distinct visualization contents during in-plane and out-of-plane operations according to their different characteristics. Use case study in this paper proved that our system can help young surgeons perform biopsy faster and more accurately.

Wang R, Tan G, Liu X. TipDet: A multi-keyframe motion-aware framework for tip detection during ultrasound-guided interventions. COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE 2024; 247:108109. [PMID: 38460346 DOI: 10.1016/j.cmpb.2024.108109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 01/09/2024] [Accepted: 02/29/2024] [Indexed: 03/11/2024]
Abstract
BACKGROUND AND OBJECTIVE Automatic needle tip detection is important in real-time ultrasound (US) images that are utilized to guide interventional needle puncture procedures in clinical settings. However, due to the spatial indiscernibility problem caused by the severe background interferences and the tip characteristics of small size, being grayscale and indistinctive appearance patterns, tip detection in US images is challenging. METHODS To achieve precise tip detection in US images against spatial indiscernibility, a novel multi-keyframe motion-aware framework called TipDet is proposed. It can identify tips based on their short-term spatial-temporal pattern and long-term motion pattern. In TipDet, first, an adaptive keyframe model (AKM) is proposed to decide whether a frame is informative to serve as a keyframe for long-term motion pattern learning. Second, candidate tip detection is conducted using a two-stream backbone (TSB) based on their short-term spatial-temporal pattern. Third, to further identify the true one in the candidate tips, a novel method for learning the long-term motion pattern of the tips is proposed based on the proposed optical-flow-aware multi-head cross-attention (OFA-MHCA). RESULTS On the clinical human puncture dataset, which includes 4195 B-mode images, the experimental results show that the proposed TipDet can achieve precise tip detection against the spatial indiscernibility problem, achieving 78.7 % AP0.1:0.5 and 8.9 % improvement over the base detector at approximately 20 FPS. Moreover, a tip localization error of 1.3±0.6 % is achieved, exceeding the existing method. CONCLUSIONS The proposed TipDet can facilitate a wider and easier application of US-guided interventional procedures by providing robust and precise needle tip localization. The codes and data are available at https://github.com/ResonWang/TipDet.

Abstract
BACKGROUND Real-time ultrasound (US) guidance facilitates central venous catheterization in intensive care unit (ICU). New magnetic needle-pilot devices could improve efficiency and safety of central venous catheterization. This simulation trial was aimed at comparing venipuncture with a new needle-pilot device to conventional US technique. METHODS In a prospective, randomized, simulation trial, 51 ICU physicians and residents cannulated the right axillary vein of a human torso mannequin with standard US guidance and with a needle-pilot system, in a randomized order. The primary outcome was the time from skin puncture to successful venous cannulation. The secondary outcomes were the number of skin punctures, the number of posterior wall puncture of the axillary vein, the number of arterial punctures, the number of needle redirections, the failure rate, and the operator comfort. RESULTS Time to successful cannulation was shorter with needle-pilot US-guided technique (22 s (interquartile range (IQR) = 16-42) vs 25 s (IQR = 19-128); median of difference (MOD) = -9 s (95%-confidence interval (CI) -5, -22), p < 0.001). The rates of skin punctures, posterior wall puncture of axillary vein, and needle redirections were also lower (p < 0.01). Comfort was higher in needle-pilot US-guided group on a 11-points numeric scale (8 (IQR = 8-9) vs 6 (IQR = 6-8), p < 0.001). CONCLUSIONS In a simulation model, US-guided axillary vein catheterization with a needle-pilot device was associated with a shorter time of successful cannulation and a decrease in numbers of skin punctures and complications. The results plea for investigating clinical performance of this new device.

Abstract
PURPOSE The aim of this study was to assess the feasibility and efficacy of an ultrasound needle guidance system (NGS) based on standard needle magnetization in a phantom study of thyroid nodule (TN)-targeting punctures. METHODS Six trainees and a staff radiologist performed TN-targeting punctures with or without the NGS in phantom models (group 1, experience <50 cases; group 2, experience ≥50 cases and <100 cases; group 3, experience ≥100 cases of TN-targeting punctures). The feasibility, technical success rate, number of punctures, and procedure time were recorded. RESULTS The feasibility of NGS was 98.6% (138/140). In group 1, the technical success rate increased from 60.0%±8.2% to 80.0%±8.2% when the NGS was used (P=0.046), with a reduction in the number of punctures from 2.2 to 1.2 (P=0.005). In group 2, the rate changed from 95.0%±5.8% to 100.0%±0.0% with the NGS (P=0.157), with a minimal decrease in the number of punctures from 1.1 to 1.0 (P=0.157). The procedure time significantly decreased in both groups (P=0.041 and P=0.010, respectively) when the NGS was used. In group 3, there were no significant differences in the technical success rate and the number of punctures according to whether the NGS was used (P=0.317 and P=0.317, respectively). CONCLUSION NGS using standard needle magnetization is technically feasible and has potential to improve the efficacy of TN-targeting punctures for less-experienced operators, especially beginners, according to the findings of this phantom study.

Abstract
BACKGROUND Peripheral intravenous access is a common medical procedure, however, it can be difficult to perform in some patients. Success rates have proved greater with ultrasound guidance. Peripheral intravenous access using ultrasound requires specific training, especially for new ultrasound users. To overcome these difficulties, guidance devices on ultrasound probes are able to control the angle of penetration into tissues. We hypothesized that, and particularly for new ultrasound users, the use of a needle guide (NG) paired with the out-of-plane approach would facilitate puncture of a simulation model of vessel more effectively than similar free hand (FH) techniques. METHODS A prospective controlled randomized study was conducted of new ultrasound users using a guide wire introducer needle on gelatine phantom. After a 30-min lecture, one group performed the FH technique and the other group performed the NG technique both in an out-of-plane approach. The main criterion was the number of attempts before success of catheterization of this model of vessel. RESULTS Thirty-four nurse anesthetist students participated in the study. The number of attempts before success using the NG technique was significantly lower: 3.7 (±0.9) in the NG group versus 6.7 (±3.3) in the FH group (p = 0.01). In the NG group, 100% of the participants achieved success after the sixth attempt. In the FH group, only 81.25% (n = 13/16) reached success. CONCLUSION NG technique has been proved to have a steeper learning curve compared with the FH technique. A study on a learning curve in clinical practice is needed to confirm these results.

Abstract
Fine-needle aspiration cytology using a novel ultrasound needle guidance system on the basis of standard needle magnetization was consecutively performed in 30 (15 in-plane and 15 out-of-plane) suspicious thyroid nodules. Nondedicated, commercially available needles were used. The technical effectiveness and safety of the system were satisfying; system failures were observed in 2 cases. The needle tip could be (at least occasionally) visualized inside the thyroid nodule in 96%, and the subjective procedure ratings were excellent in 57%. The out-of-plane technique was significantly superior in both respects (P = .021 and .027, respectively). Standard needle magnetization ultrasound needle guidance was easy to apply and cost-effective and has the potential to improve fine-needle aspiration cytology performance.

Abstract
Objective To evaluate the learnability and feasibility of a new technique comprising a needle-guidance-system (NGS) for ultrasound-assisted lumbar puncture. Method Using a randomized crossover study design, 24 medical students were asked to perform an ultrasound-assisted lumbar puncture on a gel phantom using two different techniques that each included a paramedian insertion site. Procedure 1 (P1) used a pre-procedural ultrasound scan to predetermine the ideal insertion point. Procedure 2 (P2) applied a new technique comprising an NGS for performing real-time ultrasound-guided lumbar puncture. Success rates and performance times for both procedures were compared. Participants were also asked to complete a post-study questionnaire, both to quantitatively assess the workload involved and state their personal preferences. Results In comparison to the pre-procedural scan (P1), the NGS (P2) was associated with a significant increase in the number of successful punctures per participant (5 (P2) [interquartile range: 3.3–5.0] vs. 3 (P1) [interquartile range: 1.3–4.0], p = 0.005), and led to a significant reduction in performance time (118 seconds vs. 80.6 seconds, p < 0.001). In terms of workload perception, NGS use was associated with significantly better performances and lower frustration levels, as rated by students in the post-study questionnaire. Finally, 23/24 participants stated their preference for P2. Conclusion Our newly-developed technique for real-time ultrasound-guided lumbar puncture proved to be learnable and feasible for novices, and only required a small amount of training. The use of an NGS therefore has the potential to serve as a key feature of the ultrasound-assisted lumbar puncture.
