A family of passive markers is presented by which the position and orientation of a surgical instrument can be computed from its ultrasound image using simple image processing. These markers address the problem of imaging instruments and tissue simultaneously in ultrasound-guided interventions. Marker-based estimates of instrument location can be used in augmented reality displays or for image-...

1. INTRODUCTION Rice University has a decades-long tradition of both digital signal processing (DSP) research and education, beginning in 1968. Since that time, Rice University has become a world leader and continued to be a pioneer in the DSP field. This paper will focus on the following three areas of activity at Rice. First, a brief history of DSP education and research at Rice will be prese...

BACKGROUND Advances in minimally invasive surgical techniques will require new types of instrument end-effectors for smaller, longer, and flexible instruments. These include a new class of multifunctional instruments capable of performing more than 1 task with a single set of working jaws. Furthermore, it is desired that multifunctional instruments be designed to provide improved dexterity comp...

-The data-handling sequence for the BFEM has allowed us to verify that the instrument functioned correctly and that the structures put in place provide a useful framework for analyzing the data. Many elements of this sequence will be used to process the data from the flight instrument. Some results of processing the BFEM data are discussed in another paper at this conference [7].

In this contribution a selection of instruments has been taken from Section “ (,“ which comprises instruments for operations on the genito-urinary system in the male. This section is the largest in the whole collection of surgical instruments and contains nearis’ 400 exhibits. There are numerous examples of catheters, staffs, gorgets, lithotomy forceps, lithotrites and other instruments emj)loy...

BACKGROUND As a crucial part of an image-guided oral implantology system (IGOIS), intra-operative motion tracking is important in terms of accuracy and efficiency. The tracking method, including the relevant algorithms, is described in detail. METHODS The conventional CAD method is proposed to build the three-dimensional (3D) surgical instrument models. With the application of the optical tra...

Fleet Marine Force corpsmen are the first medical responders to treat casualties in the field. They carry an outdated bag of supplies called the surgical instrument and supply set. The purpose of this investigation is to develop an updated supply set for field corpsmen by linking each supply item to specific medical tasks conducted in the field, which then creates an audit trail. The review of ...

Optical tracking systems are widely adopted in surgical navigation. An optical tracking system is designed based on the principle of stereo vision with high-precision and low cost. This system uses optical infrared LEDs that are installed on the surgical instrument as markers and a near-infrared filter is added in front of the Bumblebee2 stereo camera lens to eliminate the interference of ambie...
