Overcoming Angle Dependence in Doppler Ultrasound

Carestream’s Smart Flow technology enables detection and visualization of complex flows independent of Doppler angle

Looking at a compass, a difference of one degree seems inconsequential. Yet being off one degree on a flight path and traveling 60 miles an hour will put a plane 1 mile off course after 60 minutes. And in conventional Doppler imaging of blood flow, the wrong angle can lead to large discrepancies in results.

Ordinary color and spectral Doppler ultrasound measure the velocity of flow components only toward or away from a transducer. In conventional implementations, they use the angle of the ultrasound beam relative to the flow direction to calculate the actual flow velocity through the vessel. Thus, the accuracy of Doppler computations depends on precise knowledge of the direction of the ultrasound beam and direction of the flow in the vessel (and the angle α between them).

As the following Doppler equation illustrates, when the ultrasound beam is perpendicular to the vessel (90°), this computation is impossible, because there is no flow component in the direction of the beam.

Overcoming Limitations of CT for Orthopaedic Imaging of Extremities

Weight-bearing images show pathologies more clearly

Musculoskeletal and orthopaedic disorders are without prejudice. They plague the sports professional, the weekend athlete and even sedentary office workers.

According to the United States Bone and Joint Initiative, 77% (65.8 million) of all injury health care visits are for musculoskeletal injuries. And OSHA estimates that work-related musculoskeletal disorders in the United States account for over 600,000 injuries and illnesses. The injuries can cause pain, limit activities and require surgical repair and/or physical therapy.

Imaging the extent of these injuries, ranging from carpal tunnel to meniscus loss, has been challenging. The reason: traditional computed tomography (CT) has a significant limitation. It requires multiple rotations –and it cannot capture a weight-bearinCarestream OnSight 3D Extremity Systemg image. However, new cone beam CT (CBCT) technology from Carestream removes these restrictions. In March, we filed a 510(k) application with the FDA for clearance of the CARESTREAM OnSight 3D Extremity System, designed to offer high-quality, low-dose 3D point-of-care imaging  by orthopedic and sports medicine practices, hospitals, imaging centers, urgent care facilities and other healthcare providers.CBCT, first described in the late 1970s, is a variant of traditional computed tomography. The main difference between the two approaches is the volume of the object that is imaged at one time. In traditional CT, a narrow slice of the patient is imaged with a “fan beam” of X-rays. For an extended volume of the anatomy via CT, the patient must be imaged multiple times through the fan of X-rays as it rotates. In contrast, in CBCT, a large-area detector images an extended volume of the patient in a single rotation, reducing the complexity of the mechanical design of the system.

CIO Perspective: The IT Value Proposition of Healthcare Technologies

HealthIT technologies that are flexible provide more value to organizations

The right technology solution can be a catalyst for healthcare providers to achieve their goals. That point is not lost on today’s HealthIT leaders who ranked IT Value Proposition Carestream Vue Clinical Collaboration Platform among their top concerns for 2016 in the annual IT Trends Study from the Society for Information Management (SIM).

Not only was IT Value Proposition in the top 10 of the most important IT management issues for the organization, it was also in the top 10 of the personally most important IT management issues, coming in at No. 6 and No. 8, respectively. Their personal concern for IT’s value proposition “demonstrates that IT leaders not only consider themselves technology leaders, but also recognize the significant role they play in the achievement of organization goals,” according to the study.

Carestream’s Vue Clinical Collaboration Platform (CCP) is a great example of a technology solution with a strong health IT Value Proposition, equipping those responsible for providing, receiving and reimbursing care with the ability to share and manage clinical data in ways that can help reduce costs and improve care.  Additionally, CCP manages images with a standards-based modular platform, which means an organization can implement the programs it needs in the short term, and add additional modules at a later time as needed.

Diagnostic Reading #14: Five “Must Read” Articles on Health IT and Radiology from the Past Week

This week’s articles include: the need for greater integration between PACS and other IT tools in radiology; ability of implantable devices to improve patient care and compliance; accountable care organizations are expected to reduce costs but many patients seek care outside their network; a study examines the movement to incorporate “patient-reported outcomes” into clinical care; and Yelp reviews provide insight into patient experiences.

Survey: The state of system integration in academic radiology departments – Health Imaging

Academic radiology departments report varying levels of integration between PACS and other IT tools such as dictation systems, critical notification systems and electronic medical records, according to results of a study published online in the Journal of the American College of Radiology.

And the list keeps growing: a “bionic eye” that allows the blind to see and a cardioverter-defibrillator to treat sudden heart attacks.

ACOs using analytics, IT to manage out-of-network care – Health Data Management

Accountable care organizations are expected to reduce overall healthcare costs by coordinating care: minimizing ineffective or duplicative services and maximizing communication among the various members of each patient’s care team. At the same time, under current federal ACO rules, providers have no leverage to keep their attributed ACO patients from seeking care outside their network. A June 2014 study of care patterns in 145 ACOs, published in the Journal of the American Medical Association, found that 66 percent of specialist visits took place outside the ACO’s network.

How patients’ reports on their health can help doctors do a better job – NPR

A study published in the April issue of the Health Affairs journal examines the movement to incorporate “patient-reported outcomes” into clinical care. It may seem like a no-brainer to include patients’ assessments of their physical and mental conditions and quality of life into medical care, but such patient-generated data have traditionally been confined to research rather than clinical settings. Clinicians have typically focused more on physical exams, medical tests and biological measures to guide patient care.
Yelp provides untapped insight into patient experience – Modern Healthcare

Excessively pricey bills, long waits for staff, rude doctors and difficulties setting up appointments drove people to rant about their hospitals on Yelp, according to a study. While those issues frustrate patients, most are not tracked on government surveys and ratings programs meant to capture patients’ experiences in U.S. hospitals. Researchers say it’s a missed opportunity for actionable feedback and to identify more robust measures.

White Paper: Functional Requirements for Enterprise Clinical Data Management

Defined requirements lay the path for future growth and change2016-03-18 13_31_20-Functional_Requirements_Enterprise Data Management.pdf - Adobe Reader

As healthcare organizations plan for the future growth and integration of clinical data into their IT ecosystems, it’s crucial to start with clearly defining the functional requirements that span the needs of users across the enterprise. Why? Because well-defined functional requirements specify exactly what IT systems need to accomplish in each department and across the healthcare organization, and delineate the metrics for success. Also, functional requirements help frame the core questions posed in Requests for Proposals (RFPs) or tenders and define for vendors the capabilities that must be provided to advance interoperability and accessibility. Lastly, if your organization wants to plan for growth and change, functional requirements define the standards that must be met to ensure future compatibility and minimize disruption.

This white paper provides an overview of the key functional requirements that must be built around four distinct modules:

  • Data capture and ingestion
  • Clinical management
  • Enterprise repository/archive
  • Collaboration
