The stronger the gradient field and the wider the field of view, the greater the range of frequencies across the slice (bandwidth).\u003c/p\u003e\u003cp\u003eIncreasing the main magnetic field strength will not change the frequency range across the slice. The transmit bandwidth (which describes the range of frequencies that make up the radiofrequency pulse) is unrelated to receiver bandwidth.\u003c/p\u003e","id":2949,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2968","nextQuestionPath":"/articles/mri-physics/questions/2948","relatedArticles":[{"id":22023,"title":"Resonance and radiofrequency","link":"/articles/resonance-and-radiofrequency?lang=us"},{"id":5855,"title":"Larmor frequency","link":"/articles/larmor-frequency?lang=us"},{"id":21769,"title":"Radiofrequency coils","link":"/articles/radiofrequency-coils-1?lang=us"},{"id":60748,"title":"Effect of gradient strength and bandwidth on slice thickness","link":"/articles/effect-of-gradient-strength-and-bandwidth-on-slice-thickness?lang=us"}],"alsoUsedIn":[{"id":1927,"kind":"Course","title":"Imaging Physics: MRI - page 1927","link":"https://radiopaedia.org/courses/imaging-physics-mri/pages/1927"}],"stem":"\u003cp\u003eWhich of the following will increase the receiver bandwidth?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/2949"}],"attemptsPercentages":[{"alternativeId":"14363","percentage":18},{"alternativeId":"14364","percentage":46},{"alternativeId":"14366","percentage":24},{"alternativeId":"14365","percentage":12}],"promptToLogin":false,"questionManager":false,"articleId":"mri-physics"}
