solitary pulmonary nodule (spn) is a frequent finding on the chest x-ray and computed tomography. nuclear medicine techniques play an important role in the diagnosis and management of spn. in the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (pet) using 18-f-fdg, and 11-c-methionine, and single photon emis...

Reading a book is also kind of better solution when you have no enough money or time to get your own adventure. This is one of the reasons we show the fundamentals of computerized tomography image reconstruction from projections as your friend in spending the time. For more representative collections, this book not only offers it's strategically book resource. It can be a good friend, really go...

Computerized tomography (CT) has been used for decades by medical professionals to detect and diagnose injuries ailments. CT scanners are based on interesting physics, but due their bulk, cost, safety, hands experience with a scanner unrealistic undergraduate students. Therefore, operationally similar, yet small, safe, inexpensive desirable teaching tools. This project details the development o...

Complicated anatomical configuration of the temporomandibular joint was the reason for developing standardized radiographic techniques which would provide accurate anatomical images. Tomography provides excellent bony details but no in formation of the soft tissue component of the joint. This technique is useful in demonstrating suspected hypoplasia, hypertrophy or malformation of the condyles,...

The authors present a case of embryonal rhabdomyosarcoma of the middle ear in an adult patient. Computerized tomography indicated a malignant tumor and the diagnosis was confirmed by pathological analysis.

In this paper we propose an algebraic full multigrid algorithm for efficient and robust numerical solution of arbitrary linear systems of equations arising in image reconstruction from projections in computerized tomography. Numerical experiments and comparisons with the classical Kaczmarz algebraic reconstruction technique are presented.

The authors report an unusual location of a benign chondroma of the petro-sphenoidal synchondrosis extending into the cavernous sinus. Computerized tomography and magnetic resonance image features were characteristic of chondroid tumor. However, pathologic verification is mandatory in order to distinguish chondroma from chondroblastoma or chondroid chordoma.

The momentum and energy of phonons in a Bose-Einstein condensate are measured directly from a time-of-flight image by computerized tomography. We find that the same atoms that carry the momentum of the excitation also carry the excitation energy. The measured energy is in agreement with the Bogoliubov spectrum. Hydrodynamic simulations are performed which confirm our observation.
