Screening is defined as identification of individuals within an asymptomatic population who have specified disease at a time when intervention may result in improvement of prognosis of the disease. Identification of the disease at the earlier phases of progression improves prognosis. All kinds of cancer screening may not have same benefit. Screening for(More)
We report a case of 42 year old man who presented with one month history of weight loss, gradual abdominal distension and constipation. X-ray of the abdomen showed features of small gut obstruction. A tight stricture at the ileoceacal junction was found to be the cause of obstruction on laparotomy. Distal ileum was found to be severely inflammed with(More)
Abdominal pain, one of the major symptoms of chronic pancreatitis, is believed to be caused by obstruction of the pancreatic duct system by stones or strictures. This results in increased intraductal pressure and parenchymal ischemia. Surgical decompression of the duct and ductal drainage can achieve best pain relieve and slow the progression of the(More)
Compressed sensing (CS) or compressive sampling deals with reconstruction of signals from limited observations/ measurements far below the Nyquist rate requirement. This is essential in many practical imaging system as sampling at Nyquist rate may not always be possible due to limited storage facility, slow sampling rate or the measurements are extremely(More)
Painless scrotal masses must be investigated with ultrasound imaging and tumour marker assay before being treated with radical inguinal orchidectomy. For unknown reasons, the incidence of this cancer increased in Caucasian population. The incidence of testicular germ cell tumour has doubled in past 40 years. An annual increase of 3-6% is reported in(More)
Compressed sensing (CS) in imaging is essential in many practical situations and does need suitable algorithm for reconstruction from this highly incomplete observations/measurements. Measurements are also noisy in majority of the cases. This paper addresses CS-reconstruction of images from multiple channel data acquisition with under sampling measurements.(More)
