Controlling thick-slice viewing of breast ultrasound data
The Journal of the Acoustical Society of America, 2008An adjunctive ultrasound mammography system and associated methods are described in which an ultrasound image being displayed near an x-ray mammogram image may be superimposed thereon or thereunder by a user for facilitating rapid comprehension of breast structures and detection of abnormalities therein. In one preferred embodiment, the x-ray mammogram

Wavelet encoding for improved SNR and retrospective slice thickness adjustment
Magnetic Resonance in Medicine, 1998AbstractA method to encode the slice‐select direction in magnetic resonance imaging through the use of a discrete wavelet transform is presented. The paper reports the first implementation of wavelet encoding using the Haar basis. Theoretically, the signal‐to‐noise ratio (SNR) for two levels of wavelet encoding is expected to be approximately 1.6 times

Average thickness of tragal cartilage for slicing techniques in tympanoplasty
The Journal of Laryngology & Otology, 2015AbstractBackground:Cartilage-perichondrial grafts are often used for tympanic membrane and middle-ear reconstructions. Tragal and conchal cartilages are most frequently used for this purpose. Studies have shown that slicing the cartilage to less than 0.5 mm thickness improves acoustic benefit.

Influence of blanching and slice thickness on drying characteristics of leek slices
Chemical Engineering and Processing: Process Intensification, 2008Abstract The effect of blanching and slice thickness on drying characteristics of leek was studied. Drying experiments were performed in a cabinet dryer. Drying time decreased with blanching, but it increased considerably with increased slice thickness of leek.

Slice-thickness evaluation in CT and MRI: an alternative computerised procedure
La radiologia medica, 2012The efficient use of computed tomography (CT) and magnetic resonance imaging (MRI) equipment necessitates establishing adequate quality-control (QC) procedures. In particular, the accuracy of slice thickness (ST) requires scan exploration of phantoms containing test objects (plane, cone or spiral).

Controlling FIB‐SBEM slice thickness by monitoring the transmitted ion beam
Journal of Microscopy, 2013SummarySerial block‐face electron microscopy with focused ion beam cutting suffers from cutting artefacts caused by changes in the relative position of beam and sample, which are, for example, inevitable when reconditioning the ion gun. The latter has to be done periodically, which limits the continuous stack‐acquisition time to several days.

Brain tissue slice thickness monitored by ion-profile measurement
Journal of Neuroscience Methods, 1992The thickness of a brain tissue slice preparation governs the amount of time required for substances to diffuse from the bathing solution to preparation. Slice thickness may increase during the experiment, e.g., in cases of hypoxia where osmotic pressure within the tissue changes, enabling water to enter the preparation. With increasing slice thickness

Freeze- Drying of Carrot Slices in Diverse Thicknesses
2021In this paper we dried carrots by the method of freeze-drying. The carrots had cut in slices; then divided in halves. The mass looses of samples sized. The mass losses measured and recorded during the process. The sections were in 5 mm and 7 mm. Slices were dried with SCANVAC COOLSAFE.
