New Zealand patients have rights in relation to their healthcare including the right to consent to medical treatment. Medical imaging is the third largest category of hospital procedure in New Zealand and it constitutes a circumstance where examination without consent could be assault. New Zealand assault law is unique, and medical radiation technologists (MRTs) must be educated about their res...

The article describes some interesting and possibly not previously noticed nonlinear differential identities satisfied by exponential and trigonometric functions. Both formulation and the proofs of these relations do not require mathematics knowledge beyond standard differentiation rules and high school algebra. Surprisingly, the research that produced these identities was devoted to medical im...

There are analytic methods for designing protective barriers however, they lack sufficient efficiency and considering the NCRP (National Council on Radiation Protection and measurements) reports, designing mechanical protective barrier in order to protect the initial x-ray radiation and absorption of the ray quality of such radiation is different. In this study, computer software was designed t...

Of late, the amount of digital X-ray images that are produced in hospitals is increasing rapidly. Efficient storing, processing and classifying X-ray images have thus become an important research topic. Due to the increase in medical digital images, there is a rising need of managing this data properly and accessing them accurately. To overcome the difficulties of manual classification, the aut...

The aim of this study is to review the clinical potential of spectroscopic X-ray detectors and to undertake a feasibility study using a novel detector in a clinical hospital setting. Detectors currently in development, such as Medipix-3, will have multiple energy thresholds allowing for routine use of spectroscopic bio-medical imaging. We have coined the term MARS (Medipix All Resolution System...

Diagnostic X-ray imaging depends on the maintenance of image quality that allows for proper diagnosis of medical conditions. Maintenance of image quality requires quality assurance programs on the various X-ray modalities, which consist of pro-jection radiography (including mobile X-ray units), fluoroscopy, mammography, and computed tomography (CT) scanning. Currently a variety of modality-spec...

Most radiation therapy machines are based on microwave linear accelerators. The majority of medical accelerators use frequencies in the S-band range. Having a compact accelerator allows for a wide range of treatments. The size and weight of the accelerator is substantially reduced if a higher frequency is used. X-band frequencies are suitable for such applications. The X-band accelerator techno...

Gene therapy is defined as any therapeutic procedure in which genes are intentionally introduced into human somatic cells. Both preclinical and clinical gene therapy research have been progressing rapidly during the past 15 years; gene therapy is now a highly promising new modality for the treatment of numerous human disorders. Since the first clinical test of gene therapy in 1989, more than 60...

Effective sparse representation of X-ray medical images within the context of data reduction is considered. The proposed framework is shown to render an enormous reduction in the cardinality of the data set required to represent this class of images at very good quality. The goal is achieved by (1) creating a dictionary of suitable elements for the image decomposition in the wavelet domain and ...
