Anatomically Corrected DVH Metrics Accounting for Intrafraction Motion of Esophagus in Dorsal Spine SBRT

Ultrasound for intrafraction motion monitoring

Anatomically corrected malposition of great arteries

Anatomically corrected malposition of great arteries (ACMGA) is a rare form of congenital heart disease in which the great arteries arise above the anatomically correct ventricles but have abnormal spatial relationship. We report the case of a 26-year-old female with ACMGA and tunnel type of subaortic obstruction. The abnormal relationship and segmental arrangement necessitates systematic appro...

Quality assurance device for four‐dimensional IMRT or SBRT and respiratory gating using patient‐specific intrafraction motion kernels

Emerging technologies such as four-dimensional computed tomography (4D CT) and implanted beacons are expected to allow clinicians to accurately model intrafraction motion and to quantitatively estimate internal target volumes (ITVs) for radiation therapy involving moving targets. In the case of intensity-modulated (IMRT) and stereotactic body radiation therapy (SBRT) delivery, clinicians must c...

Anatomically corrected transposition of the great arteries.

It has long been doubted whether or not it is possible for a transposed aorta to arise from a morphologically left ventricle, and for a transposed pulmonary artery to originate from a morphologically right ventricle, this having been designated anatomically corrected transposition by Harris and Farber in 1939. Such cases have been regarded as errors in observation (Lochte, 1898), as inexplicabl...

TU-E-BRB-02: A Decision Support Tool for SBRT Planning Using a Searchable DVH Database.

PURPOSE Develop a decision support tool that aids dosimetrists, physicians, and physicists in assessing and improving plan quality through comparison to plans previously used in similar clinical situations. METHODS Software was developed to capture and store DVHs and other clinically relevant treatment plan characteristics in a database. In addition to the plan DVH, the database contains a to...
