Introduction Artificial intelligence (AI) models trained on audio data may have the potential to rapidly perform clinical tasks, enhancing medical decision-making and potentially improving outcomes through early detection. Existing technologies depend limited datasets collected with expensive recording equipment in high-income countries, which challenges deployment resource-constrained, high-volume settings where a profound impact health equity. Methods This report introduces novel protocol...
Abstract Purpose This study aimed to describe the workflow and evaluate accuracy of a novel smartphone augmented reality (AR) application that includes an integrated needle guide, in phantom. Materials Methods A cover with guide was designed 3D-printed. An AR for percutaneous developed, which projected path based on rigid guide. After planning using this tool, operator could place through reach target. Six lesions out-of-plane entry points were targeted abdominal Timing placements measured...
Abstract Purpose Targeting accuracy determines outcomes for percutaneous needle interventions. Augmented reality (AR) in IR may improve procedural guidance and facilitate access to complex locations. This study aimed evaluate placement using a goggle-based AR system compared an ultrasound (US)-based fusion navigation system. Methods Six interventional radiologists performed 24 independent placements anthropomorphic phantom (CIRS 057A) four cohorts ( n = 6 each): (1) US-based fusion, (2) with...
In CT-guided intervention, translation from a planned needle insertion angle to the actual is estimated only with physician's visuospatial abilities. An iPhone app was developed reduce reliance on operator ability estimate and reproduce angles.The overlays smartphone's camera display in real-time based orientation. The needle's selected by visually comparing guideline display. If screen perpendicular path, smartphone shows Bull's-Eye View mode, which after hub overlaps tip camera. phantom...
Purpose: A novel grid-template-mimicking MR-compatible robot was developed for in-gantry MRI-guided focal laser ablation of prostate cancer. Method: substantially compact designed and prototyped to meet lithotomy ergonomics allow accommodation in the perineum. The controller software reconfigured integrated with custom-designed navigation multi-focal software. Three experiments were conducted: (1) free space accuracy test; (2) phantom study under computed tomography (CT) guidance...
PurposeAn augmented reality (AR) system was developed to facilitate free-hand real-time needle guidance for transperineal prostate (TP) procedures and overcome the limitations of a traditional grid.ApproachThe HoloLens AR enables superimposition annotated anatomy derived from preprocedural volumetric images onto patient addresses most challenging part TP by providing tip localization depth visualization during insertion. The accuracy, or image overlay accuracy (n = 56), targeting 24) were...
Transapical aortic valve replacement under MRI guidance in a beating heart is recent minimally invasive technique that could benefit from surgical assistant system. We present robotic system can precisely and repeatably deliver prostheses. The consists of an imaging system, Innomotion arm, 3-DoF delivery module user interfaces. Interactive control allows the physician to remain loop adjust orientation position using real-time MR feedback. developed deploy both balloon-expandable...
Purpose: A new version of a grid-template-mimicking MR-compatible robot is developed to assist during in-gantry MRI-guided focal laser ablation prostate cancer. This replaces the grid template and provides higher positioning resolution, allows autonomous needle alignment directly from targeting navigation software, with insertion manually performed for safety. Method: substantially more compact solution designed prototyped allow comfortable accommodation between patient's legs while in MRI...
Purpose: This study aims to investigate the accuracy of a cross platform augmented reality (AR) system for percutaneous needle interventions irrespective operator error. In particular, we effect relative position and orientation AR device marker, location target, angle on overlay accuracy. Method: A guidance developed using Unity Vuforia SDK platforms was used display planned trajectory targets via mobile wearable devices. To evaluate accuracy, custom phantom embedded with metal fiducial...
Purpose: This study aims to analyze a social distance monitoring and contact tracing assistance tool for preventing the spread of COVID-19 in busy indoor working hospital environment. Method: A camera-based was developed. The estimates physical between multiple individuals real-time also tracks records their time when violation requirements retrospect review. Both stereo- monocular-camera tools are implemented accuracy efficiency evaluated compared. Video captured by ZED M camera which set...
The success of artificial intelligence in clinical environments relies upon the diversity and availability training data. In some cases, social media data may be used to counterbalance limited amount accessible, well-curated data, but this possibility remains largely unexplored. study, we mined YouTube collect voice from individuals with self-declared positive COVID-19 tests during time periods which Omicron was predominant variant 1,2,3 , while also sampling non-Omicron variants, other...
In transperineal prostate biopsy or ablation, a grid-template is typically used to guide the needle. The guidance method has limited positioning resolution and lack of needle angulation selections that are referenced ultrasound imaging TRUS-MRI fusion targets. To overcome limitation, novel augmented reality (AR) system use smart see-through glasses smartphone as device for procedure was developed. AR comprised MRI/CT scanner, pre-procedural image analysis visualization software, devices...
Accurate needle placement largely depends on physicians' visuospatial skills in CT-guided interventions. To reduce the reliance operator experience and enhance accuracy, we developed an augmented reality system using smart seethrough glasses to facilitate assist bedside angle guidance. The AR was Unity Vuforia SDK. It displays planned glasses' see-through screens real-time based orientation. displayed is always referenced CT table independent from physical orientation of glasses. feature...
Wheelchairs are widely used in our life. A lot of old people, many disabled individuals need the help wheelchairs. This article instructs a wheelchair that can climb stairs without other people's helps. And analyze stability process. We divide into three parts, system wheels, back part and support frame wheelchair.
