A Novel Phantom Model For Mouse Tumor Dose Assessment Under MV Beams

By: Michael Gossman, MS, DABR, RSO, et al

Abstract -- In order to determine a mouse's dose accurately and prior to engaging in live mouse radiobiological research, a tissue-equivalent tumor-bearing phantom mouse was constructed and bored to accommodate detectors. Comparisons were made among four different types of radiation detectors, each inserted into the mouse phantom for radiation measurement under a 6 MV linear accelerator beam.

Dosimetric Effects Near Implanted Vascular Access Ports: An Examination Of External Photon Beam Dose Calculations

By: Michael Gossman, MS, DABR, RSO, et al

Vascular access ports are used widely in the administering of drugs for radiation oncology patients. Their dosimetric effect on radiation therapy delivery in photon beams has not been rigorously established. In this work, the effects on external beam fields when any of a variety of vascular access ports were included in the path of a high energy beam are studied. This study specifically identifies sidescatter and backscatter consequences as well as attenuation effects.

Valuing a Professional Practice Requires In-depth Analysis

By: Michael J. Garibaldi CPA, ABV, CFF, CGMA

Goodwill can be a significant asset for a professional practice. It may include both "personal" goodwill that's attributable to individual owners and "business" goodwill that can be transferred to third parties. When accountants and other types of professionals divorce, the amount of goodwill to include in the marital estate can become contentious (and may vary depending on state law). If expert testimony on the issue is inadequate, a court might look elsewhere for help, as it did in a recent Texas divorce case, Hill v. Hill.

Understanding Financial Misstatement: The Least Common Type Of Fraud Can Also Be The Costliest

By: Michael J. Garibaldi CPA, ABV, CFF, CGMA

Business Valuations: Different Values for Different Purposes?

By: Michael J. Garibaldi CPA, ABV, CFF, CGMA

There are many more purposes for which valuations are used. Each has its unique presumptions. It must be understood that there is no one value and that the same investment can have a different value to different people and for different reasons. Each valuator must analyze such differences, understand the presumptions inherent in the purpose for which the valuation is to be used, and select and implement a method to determine proper value for the purpose.

Confirming Worst Suspicions: Hire a Forensic Expert To Find Hidden Assets

By: Michael J. Garibaldi CPA, ABV, CFF, CGMA

When a client voiced strong suspicions that her soon-to-be ex-husband was hiding assets, her attorney investigated the claim but found nothing amiss. However, he hired a forensic accounting expert to help ensure his client would receive an equitable share of the marital estate. The expert turned up a trunkload of hidden treasure - undeclared cash income and property "stashed" under the names of the husband's mother and siblings.
