AHC interview with Rochelle R. Lambert
No full textRochelle (Rachel) Lambert, née Habermann, was born on December 23, 1920 in Vienna, where she lived with her parents and her brother, Joshua in the 3rd District (Landstrasse). She was expelled from Radetzky Realgymnasium after ‘Anschluss’ and was not allowed to finish school in Austria. Her parents arranged visas for the United States and sent her along with her brother to relatives in New York in 1938. Joshua Habermann was accepted to the rabbinical seminary in Cincinnati, Ohio and became a rabbi in Washington. Rachel Habermann was able to continue her education with a scholarship from the Schmidlapp Foundation and became a beautician. Her parents joined her in New York in 1940, and they opened a store together
Application of CT in Diagnosing Carcinoma of the Maxillary Sinuses : PART 2: An Experimental Study of Pitfalls Encountered when Diagnosing Carcinoma of the Maxillary Sinuses with CT
No full text1982-03A phantom simulating the transverse section of the maxillary sinuses was constructed for experimentation with various CT scanners to study the following: (1) the occasional inability to image the very thin posterior-lateral walls which have no real bone defects, and (2) to verify whether or not the bony walls surrounding the maxillary sinuses are actually as thick as they appear on CT. The phantom was made of an acrylic cylinder containing three cavities simulating the maxillary sinuses and the nasal cavity and filled with water. The walls, made of thin aluminum and acrylic plates and placed between water and air, disappeared in some CT images. The thickness of the walls calculated from CT values was greater than the true thickness imaged by each CT scanner. The author stresses that in CT images, either experimentally or clinically, thin bony walls placed between water and air or fat tend to disappear, and that bony walls tend to appear thicker than their true thickenss.departmental bulletin pape
CT-ED conversion on a GE Lightspeed-RT scanner: influence of scanner settings
No full textThe influence of tube voltage (kV) and current (mA) on the resulting relationship of computed tomography number to electron density (CT-ED) was investigated for a wide-bore GE scanner. The influence of kV and mA scan settings were examined in combination with a 16-bit image reconstruction algorithm made available via the scanner software and which allowed resolution of CT numbers for high density materials. By using titanium and stainless steel inserts in an electron density phantom, mA variation was found to have minimal impact on the CT-ED relationship, whereas variation in kV led to significant differences in CT number for the high density materials. The scanner is also equipped with automatic tubecurrent modulation capabilities. The influence of automatic tube-current modulation on CT number was investigated for a range of materials in a phantom geometry. It was found that tube current modulation has negligible effect on CT number, though the changing dimension of the phantom did influence CT number of an aluminium insert for scans undertaken with both fixed and modulated tube currents. In light of evidence from other studies examining the influence of CT number on dose calculation, it is recommended that scanner settings and specific CT-ED look-up tables be considered when calculations will be required with high-density materials present
