1. The incurable cancer patient at the end of life : Medical care utilization, quality of life and the additive analgesic effect of paracetamol in concurrent morphine therapy
Sammanfattning : Only 12% of the patients died at home. When the period between diagnosis and death was less than one month, every patient died in an institution. Younger patients, marriedpatients, and those living within the 40 km radius of the hospital utilized more hospital days. LÄS MER
2. Quantitative SPECT : studies of some factors influencing quantitation accuracy in single photon emission computed tomography
Sammanfattning : .... LÄS MER
Sammanfattning : Single Photon Emission Computed Tomography (SPECT) is used to image functional processes in the human body. The image process is affected by physical effects such as attenuation, scatter, spatial resolution and statistical noise. LÄS MER
Sammanfattning : A quantitative evaluation of single photon emission computed tomography (SPECT) and planar scintigraphic imaging may be valuable for both diagnostic and therapeutic purposes. For an accurate quantification it is usually necessary to correct for attenuation and scatter and in some cases also for septal penetration. LÄS MER
5. Calibration of Ionization Chambers for Measuring Air Kerma Integrated over Beam Area in Diagnostic Radiology
Sammanfattning : The air kerma area product PKA is an important quantity used by hospital physicists in quality assurance and optimization processes in diagnostic radiology and is recommended by national authorities for setting of diagnostic reference levels. PKA can be measured using a transmission ionization chamber (kerma area product (KAP) meter) mounted on the collimator housing. LÄS MER
