  3. The B scan is usually performed by placing the transducer on the patient's closed eyelid. It creates the typical 2D image that you associate with ultrasound. Ultrasound biomicroscopy (UBM) is performed with a much higher frequency than the A and B scans and is primarily used to evaluate the anterior chamber angle and ciliary body

B-scan probe. The B-scan probe is a two-dimensional echo display that is used to determine the topographic features of posterior segment pathology including location, shape and extent of lesions See Clip 3.1.B-scan probes have a marker along the side of the probe close to the probe tip that indicates the top of the B-scan ultrasound display (Figure 3.2A) For a beginner to interpret it is important to know what schitic and cystic spaces look like ( just an example) So it'll be helpful if they are arrowd down or numbered.

B-Scan Presentation. The B-scan presentations is a profile (cross-sectional) view of the test specimen. In the B-scan, the time-of-flight (travel time) of the sound energy is displayed along the vertical axis and the linear position of the transducer is displayed along the horizontal axis B-scan is used to assess the gross mobility of vitreous opacities and membranes. After movement is evaluated before, during, and as soon as an eye movement ceases. With the patient fixating a target, the lesion is imaged on the screen CONCEPTS OF B-SCAN INTERPRETATION. Interpretation of a B scan for accurate diagnoses of posterior segment disease depends on three concepts: • Real time • Gray scale • Three-dimensional analysis. Real Time. Ultrasound B-scan images can be visualized at approximately 32 frames/s, allowing motion of the globe and vitreous to be easily detected

B-scan, or brightness scan, is another method used for ocular assessment via ultrasound. It can be performed directly on the anesthetized eye.

• B-scan or brightness modulation scan provides two dimensional images of a series of dots and lines. • B-scan provides the topographic information of shape, location, extension,mobility, and gross estimation of thickness of the tissue. 3 B-scan ultrasonography is an important adjuvant for the clinical assessment of various ocular and orbital diseases. With understanding of the indications for ultrasonography and proper examination technique, one can gather a vast amount of information not possible with clinical examination alone Ultrasonography in retinal detachment 751 tachment and/or dense vitreal fibrous bands are at present excluded, since a visual result is unlikely to be obtained.

• B-scan Ultrasonography. B-scan is considered to have high sensitivity and specificity for the detection of ONHD. 2,11 In the general patient, the optic nerve appears as a tubular structure with low homogenous reflectivity. Drusen appear as hyperreflective calcified bodies in the optic nerve and will continue to show increasing brightness even at a low gain The resolution obtained by OCT is 1-2 orders of magnitude higher than ultrasound, and has been demonstrated to work on both transparent and non-transparent tissue with high reflection. In OCT many one-dimensional scans (a-scans) are performed at several depths to create a two-dimensional image (b-scan)

Glaucoma -RNFL Thickness Analysis The RNFL thickness map shows the patterns and thickness of the nerve fiber layer within the 6mm x 6mm cube • The RNFL deviation map is overlaid on the OCT fundus image to illustrate precisely where RNFL thickness deviates from a normal rang Abstract: Ground-penetrating radar (GPR) has been widely used as a nondestructive tool for the investigation of the subsurface, but it is challenging to automatically process the generated GPR B-scan images. In this paper, an automatic GPR B-scan image interpreting model is proposed to interpret GPR B-scan images and estimate buried pipes, which consists of the preprocessing method, the open.

The same techniques are useful in anterior segment high resolution B-scan as well but that will be a subject for a future white paper. For those new to ultrasound, understanding this unique imaging concept of Real Time is a stepping stone to successful interpretation of diagnostic images.

The true definition according to BS EN 1330-4:2000 is the 'Image of the results of an ultrasonic examination showing a cross-section of the test object perpendicular to the scanning surface and parallel to a reference direction

Doctors will interpret the bone scan results and discuss them with you, but you may also wish to see the results for yourself. The results of a bone scan imaging test are typically available about two days following the procedure. After evaluating the results, the patient may need to undergo other diagnostic tests to verify the findings b) Scan back to midline, then angle to the right to visualize the right lobe of the liver, including the position of the IVC where it passes through the liver.

SADDA, MD. T he advent of optical coherence tomography has revolutionized imaging in ophthalmology since its introduction two decades ago. OCT is a noninvasive system that allows for cross-sectional imaging in vivo, using light waves, which are akin to the sound. The technical component is the performance of the test and acquisition of images, while the professional component is the interpretation of the test and creation of a detailed written report. It is necessary to have copies of the ultrasound images in the patient's medical record as proof the procedure was performed

Now that B scan is truly compact, easy to use and interpret, portable and affordable, it is likely that many optometrists will consider acquiring this new technology The B-scan is useful to indicate the position of a retinal or vitreous detachment, or of an intraocular foreign body or a tumour, and for the examination of the orbit. The B-scan is especially useful in the examination of the posterior structures of the eye when opacities prevent ophthalmoscopic examination (e.g. cataract, corneal oedema)

Optic nerve head drusen (ONHD) are globular, often calcified, hyaline bodies located within the optic nerve head. The incidence of ONHD is 3.4 per 1000 in clinical studies; however, a higher rate of 10 to 20 per 1000 has been reported in autopsy studies. Pedigree studies suggest that drusen of the optic disc is a hereditary anomaly most compatible with the theory of irregular dominance with.
