Breast ultrasound AI: a full-process smart solution from screening to precision treatment

01 Opening Remarks

02 Disease Burden and Clinical Challenges

2.1 Disease Burden：A Public Health Challenge That Cannot Be Ignored

Chinese women have about 420,000 new cases of breast cancer.，是女性恶性肿瘤首位。Behind these figures lie the health challenges faced by tens of millions of patients and their families。 The incidence of breast-related diseases continues to increase as population ageing accelerates, lifestyles change and environmental factors influence。 Of even greater concern are the early absence of specific symptoms of many breast diseases and the fact that patients tend to be in the middle and late stages of the disease at the time of their visit, resulting in a significant reduction in the effectiveness of treatment and in the prognosis.。

以乳腺Ultrasoundas the core的Imaging学检查，是乳腺疾病诊断和治疗决策的基石。 然而，High breast ultrasound positive.——这一data深刻反映了当前乳腺Ultrasound（Ultrasound）诊断面临的核心挑战。 A considerable proportion of patients fail to receive an accurate diagnosis within the optimal treatment window, which not only delays treatment but also increases the medical burden and the suffering of patients。 How to improve the early diagnosis rate and accuracy of breast diseases is an important challenge currently facing clinical medicine。

2.2 Three Major Pain Points in Clinical Diagnosis

2.3 The Capability Gap in Primary Care

Insufficient Primary Care Capability。This data reveals a serious reality: the high-quality Ultrasoon diagnostic resources are concentrated in the big city's Triple Hospital. Primary-care medical institutions have obvious shortcomings in equipment, talent reserves and diagnostic capability。For the vast number of primary-care patients, obtaining high-quality breast imaging diagnostic services is not easy。

This uneven distribution of health-care resources not only exacerbates the social problem of "difficult and expensive" but also limits the spread of early detection of breast diseases.。 How to use artificial intelligence technology to break down geographical barriers and bring high-quality ultrasound diagnostic capability down to the primary care level, is one of the core issues that Changsha Langhui Information Technology Co., Ltd. has long focused on and is committed to solving。

3.1 Four Major Limitations of Traditional Manual Diagnosis

Although ultrasound technology has made great strides over the past few decades, the traditional manual image reading model is facing more and more challenges。 From image acquisition and analytical interpretation to report generation, every stage has bottlenecks that are difficult to break through。

3.2 Core advantages of AI technology

以深度学习为代表的人工智能技术，正在从根本上改变乳腺Ultrasound（Ultrasound）的诊断范式。 AI has the following irreplaceable advantages over traditional artificial diagnosis:

3.3 Triple value of AI breakdown

人工智能技术在乳腺Ultrasound（Ultrasound）Domains的应用，不仅仅是效率的提升，更是诊断模式的根本变革。 Its core values are reflected at three levels:

04 2025-2026 Frontier Technology Breakthroughs

The period from 2025 to 2026 is a critical phase of accelerated iteration in ultrasound AI technology。Foundation models, self-supervised learning, Multimodal Fusion（Multimodal Fusion）等Frontier技术的快速发展，正在将乳腺ImagingAI推向一个全新的高度。 The following are the five technology breakthrough directions most worthy of attention in this field。

4.1 Base model: from "special AI" to "general AI" Viet.

长期以来，乳腺Ultrasound（Ultrasound）AIModels大多是针对单一Tasks进行Training的"专用Models"。 However, with the rise of foundation model technology, this landscape is undergoing a fundamental change。 A general-purpose vision foundation model pre-trained on large-scale medical imaging data can be adapted to a wide range of downstream tasks with only minimal fine-tuning, greatly reducing the cost and cycle of model development。

In 2025, several top international teams successively released foundation models designed specifically for medical imaging。These models are pre-trained on hundreds of millions or even billions of medical images, learning rich feature representations of medical images。在乳腺Ultrasound（Ultrasound）Tasks上，这些基础Models展现出了惊人的性能， setting new state-of-the-art records on multiple benchmarks。More importantly, they demonstrate powerful generalization capability and few-shot learning ability, providing a new approach to solving the "data scarcity" pain point in the field of medical AI。

Changsha Langhui Information Technology Co., Ltd. is also actively positioning itself in this direction。基于40,000+例乳腺Ultrasounddata乳腺Imagingdata， LanghuiResearch院正在Training专门针对乳腺Ultrasound（Ultrasound）的Domains基础Models。 Preliminary results show that the model achieved excellent performance across multiple breast disease diagnosis tasks, Compared with traditional single-task models, performance improves significantly and generalization capability is stronger。

4.2 Self-Supervised Learning：Unleashing the Huge Value of Unlabeled Data

In medical imaging, annotated data is costly and time-consuming to acquire, while unlabeled data is relatively abundant。 How to effectively leverage massive amounts of unlabeled data has always been one of the core topics in medical AI research。 The maturity of self-supervised learning technology provides an effective solution to this problem。

2025 Years以来，自监督学习在乳腺Ultrasound（Ultrasound）Domains取得了一系列重要进展。 By designing ingenious pre-training tasks (such as image inpainting, contrastive learning and masked image modeling), allowing models to learn useful feature representations from massive amounts of unlabeled ultrasound images。 Experiments show that models pretrained with self-supervised learning can match or even exceed fully supervised training results on downstream diagnostic tasks using only a small amount of annotated data。

This technological breakthrough has important practical significance。It means that for some rare and uncommon diseases, Even with limited annotated data, self-supervised pre-training can be used to build AI models with strong performance。 At the same time, self-supervised learning offers a new paradigm for multi-center data collaboration — individual centers do not need to share raw data or annotations, Simply sharing the knowledge from model pre-training enables collective progress。

4.3 Multimodal Fusion：Comprehensive Diagnosis Integrating Imaging, Clinical and Genomic Data

Clinical diagnosis has never been a single-modality decision。In real clinical practice, doctors need to comprehensively consider the patient's imaging findings, Clinical symptoms, laboratory tests, family history and even genetic test results must all be considered to arrive at the most accurate diagnosis。 Multimodal fusion technology is precisely what enables AI to acquire such comprehensive analytical capability。

In 2025-2026, multimodal fusion made remarkable progress in breast disease diagnosis。 Researchers have developed a variety of effective multimodal fusion strategies, including early fusion, late fusion and hybrid fusion architectures, as well as attention-mechanism-based cross-modal feature interaction methods。 These technologies enable AI models to simultaneously process ultrasound images, clinical text, laboratory data and other types of information, outputting more comprehensive and more precise diagnostic results。

以乳腺肿瘤诊断为例，MultimodularAIModels不仅能够分析Ultrasound（Ultrasound）Image中的肿瘤形态学特征， It can also incorporate the patient's tumor marker levels, clinical manifestations, genetic test results and other information, making more accurate predictions of tumor benignity and malignancy, invasiveness and prognosis, providing clinicians with more valuable decision support。

4.4 Empowerment by Large Language Models：End-to-End Intelligence from Image to Report

The rise of large language models (Large Language Model, LLM) has opened up new possibilities for ultrasound AI。 By combining vision models with language models to build vision-language multimodal large models, enabling the direct generation of structured, standardized diagnostic reports from ultrasound images, This will greatly improve the work efficiency of radiology departments。

In 2025, several research teams have already achieved important breakthroughs in this direction。 The vision-language model they built can not only accurately identify various breast lesions, It can also generate imaging reports that comply with clinical standards and have a clear structure。 Even more exciting is that these models also possess a certain "conversational" capability, Doctors can interact with the model in natural language, asking various questions about the image, This brings a brand-new human-machine collaboration experience to clinical work。

4.5 Explainable AI: Transparent and credible AI decision-making

In the medical field, the explainability of AI models is of critical importance。A "black box" AI system, No matter how high the performance, it is difficult to gain the trust of clinicians and the approval of regulators。 In 2025-2026, explainable AI (Explainable AI, XAI) made important progress in the field of ultrasound。

Research人员开发出了多种针对乳腺Ultrasound（Ultrasound）AI的可解释性方Law， Including attention-based visualization methods, feature attribution-based explanation methods, concept activation vectors and more。 These methods allow doctors to clearly see which regions and which features of the image the AI model based its diagnostic decision on, greatly enhancing the transparency and trustworthiness of AI systems。

Changsha Langhui Information Technology Co., Ltd. has also conducted in-depth exploration in explainable AI。 Langhui's breast AI system not only provides diagnostic conclusions, It also presents the basis of the model's decisions to doctors through heatmaps, feature annotations and other means, allowing doctors to "know not only what the AI concludes, but also why" when using AI assistance。
