“…Results presented by Kowal et al 41 are comparable with ours in terms of accuracy performances, but worse (one order of magnitude) in terms of precision. Recently, Mercier et al 4 reported 0.64 mm as mean value for the point reconstruction accuracy. Chen et al, 42 who performed beam thickness correction in the calibration, 21 reached a similar value (0.66 mm as mean accuracy).…”

Purpose : In this paper a new, easy‐to‐manufacture and easy‐to‐use ultrasound (US) probe calibration phantom for 3D freehand scanning is presented and evaluated, together with a new method for achieving an accurate and user‐robust calibration using virtual plane. Methods : The phantom allows the optically tracked US probe to perform two rotations and two translations while keeping the image of a tensioned wire in the image plane. This approach allows obtaining a sharp image of the wire independently from the probe pose. The virtual plane allows the calibration algorithm to converge minimizing the required number of US probe tracked poses. The US image and position data are synchronized via a CORBA interface, created within the Image Guided Surgery Toolkit (IGSTK) framework. The calibration algorithm and the calibration protocol were evaluated in a set of experiments carried out by different test‐users. Results : The calibration method proved to be accurate and precise: 3D point reconstruction accuracy resulted 0.2 mm as mean value, while the precision was 0.4 mm as standard deviation. Conclusions : The technique showed to be suitable for medical applications from morphological diagnosis to intraoperative surgical planning adaption.

“…IOUS helped to locate and show the affected areas detected with ECoG by real-time imaging. We performed IOUS using aLogiq p6 (GE Healthcare, Washington) and a linear transducer (7)(8)(9)(10)(11). The probe was placed on the frontal pole and displayed the abnormal frontal lobe parenchyma with homogeneously hyperechoic expanded gyri (Fig.…”

Focal megalencephaly: intraoperative ultrasound imaging in epilepsy surgery

et al. 2014

Hemimegalencephaly is a rare neuronal migration disorder that can be defined as abnormal neural and glial proliferation localized to all or part of a cerebral hemisphere. Most patients demonstrate intractable epilepsy, with early onset before 1 year of age. Surgical resection is one of the treatment options. In recent years, many advanced intraoperative techniques have been used for brain surgery for various pathologies. Intraoperative ultrasonography is a time-saving and noninvasive method for intraoperative imaging. In this report, we present the use of intraoperative ultrasonography in a patient with focal megalencephaly as an anatomical navigation with the functional navigation system, electrocorticography. In this report, we present the use of intraoperative ultrasonography in a patient with focal megalencephaly as an anatomical navigation with the functional navigation system, electrocorticography.

“…For spinal neurosurgery we can also add measures of amount of residual tumor detected [15] and rates of various complications [16]. Other complications not mentioned in the above audits or registry studies are: Vascular injury including blood loss or (rare) iatrogenic thoracic aortic injury cases [17,18]; radiation injury [19].…”

“…Ultrasound imaging also has potential to be used in spinal navigation [15,34]. Kolstad et al outline the problem of 2D ultrasonography in the positioning of the operating instruments since the orientation of the probe must be taken into account to estimate the depth of the lesion, whereas 3D-US (where an image volume is generated by tilting or translating the probe) is able to locate the probe in 3D space.…”

User requirements for image-guided navigation in spinal surgery

2013

View full text Add to dashboard Cite

Abstract-Advances in image-guided technology have resulted in a number of technologies to support surgeons in the identification of tissue and the tracking and navigation of surgical instruments in spinal surgery. There are various existing and proposed systems to support registration and intraoperative image guidance based on fluoroscopy, Computerized Tomography (CT), Magnetic Resonance Imaging (MRI) and ultrasound (US) or combinations of imaging modalities. However, the user requirements for the design of such systems are complex, dependent on medical specialty in addition to the range of instrumented and non-instrumented treatments offered in the orthopedic and neurological domains. This paper presents a review and study of user requirements for intraoperative navigation in spinal surgery. The numerous outcomes measures for successful operations are outlined, that provide a basis for understanding the needs of surgeons. A hierarchy of needs is then presented that can be used to inform an Analytic Hierarchy Process for elicitation of detailed user requirements.
