"The labeling and measuring of free hand ultrasound images are operator dependent, time consuming, and are usually manually performed," said Calin Caluser, MD, lead author of the study. "The new 3-D mapping and labeling system that we have developed automatically records information and replaces steps in the image acquisition process (that are typically performed manually) with a simple key stroke," said Caluser.
The study measured the timing and accuracy of the new system in a realistic breast ultrasound phantom with small masses scattered throughout. "Results showed that the average scanning time per target using the new mapping and labeling system was up to 16 seconds per target; compared to at least 51 seconds per target using the standard scanning protocol. The system accurately measured and recorded the location of the masses in relation to the nipple (up to 2 mm), which is difficult to obtain using the manual method," said Caluser.
"The new system can be added to any existing ultrasound machine and the reduced time for scanning the patient can translate in improved work flow and efficiency," he said.
"In addition to the reduced examination time, there are other potential benefits to the patients. The mapping and labeling system can help obtain a second opinion from a different physician, may reduce the number of repeat ultrasound exams, and also could help in planning a patient's treatment. With clinical experience, we hope to improve the system and bring more features to help the patients and health care providers," said Caluser.
This study will be on exhibit from Sunday, May 2 – Friday, May 7. For a copy of the abstract or to schedule an interview with Dr. Caluser, please contact Heather Curry via E-MAIL at firstname.lastname@example.org.
The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Röentgen, who discovered the x-ray in 1895.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
